Example: Configuring Connectivity Fault Management for a PBB Network on MX Series Routers

Provider backbone bridging (PBB) extends Layer 2 Ethernet switching to provide enhanced scalability, quality of service (QoS) features, and carrier-class reliability in service provider networks. Connectivity fault management (CFM) is used with PBB to support that carrier-class reliability. Use CFM to monitor, isolate, and verify faults in the network.

The JUNOS Software implementation of PBB supports the IEEE 802.1ah (PBB) and IEEE 802.1ag (CFM) standards.

This example describes how to configure end-to-end fault management in a PBN and a PBBN:

Requirements

This example uses the following hardware and software components:

  • JUNOS Release 10.0 or later for MX Series routers
  • Eight MX Series routers in a PBB configuration

Before you configure the routers for PBB and services, be sure you have:

Overview and Topology

There are two different networks that need to be configured for CFM in this example:

  • A provider backbone bridge network (PBBN).
  • Provider bridged networks (PBNs) that include PBN1, PBN2, and PBN3.

This example uses a series of maintenance end points (MEPs) and maintenance intermediate points (MIPs). MIPs respond to the OAM processes initiated by the MEPs. Using MEPs and MIPs, CFM provides end-to-end connectivity in the PBBN because it can exactly pinpoint a failure in the topology.

Figure 1 displays the topology for the PBBN. The PBBN connect the PBNs and provides services to the PBNs. Two backbone core bridges (BCBs) are connected to PBN1, PBN2, and PBN3. Operation, Administration, and Maintenance (OAM) in the PBBN is limited to fault detection in the PBBN.

Figure 1: Network Topology for the PBBN

Table 1 shows the maintenance end points (MEPs) and maintenance intermediate points (MIPs) that are configured for each router in the PBBN. The PBBN is configured with VLAN 3150 and 3350. CFM must be configured for monitoring the connectivity in both the VLANs. To do this, configure a MEP for each VLAN at the endpoints (BEBs), and configure a MIP for each VLAN on the core bridges (BCBs).

To configure a MIP for level x, the maintenance domain default-x is configured on the router. For example, if MEPs in the PBBN are configured at level 3, the MIP is configured as default-3.

Note: CFM in the PBBN is used to check the connectivity in the PBBN domain only, and packets are never leaked to the PBN.

Figure 2 displays the topology for PBN. BEB1, BEB2, BEB3, and BEB4 are connected to customer edge switches ES1, ES3, and ES4.

The PBN is configured with VLAN 500 and 600. CFM must be configured for monitoring the connectivity in both the VLANs. To do this, configure a MEP for each VLAN at the endpoints (ESs), and configure a MIP for each VLAN on the BEBs.

Comparing both topologies, notice that the BEBs are actually part of both the PBN and the PBBN. They perform the function of a MEP in the PBBN, but perform the function of a MIP in the PBN and participate in multiple maintenance domains. In comparison, BCBs in the PBBN participate in one maintenance domain and ESs in the PBN participate in one maintenance domain.

Note: CFM on the PBN is used to check the connectivity in the PBN domain—these packets are simply tunneled in the PBBN domain as data packets.

set protocols oam ethernet connectivity-fault-management maintenance-domain pbbn maintenance-association vlan3150 mep 100 auto-discovery

Step-by-Step Procedure

To configure a MEP for BEB1:

  1. Create a maintenance domain at level 5 for PBBN monitoring (here, the maintenance domain is pbbn):

    [edit protocols oam]
    user@beb1# set ethernet connectivity-fault-management maintenance-domain pbbn level 5

  2. Configure the continuity check interval for the maintenance association (here, vlan3350). The continuity check protocol is used for fault detection by a Maintenance End Point (MEP). The MEP periodically sends continuity check multicast messages, and receiving MEPs use the CC messages to build a MEP database of all MEPs in the maintenance association.

    [edit protocols oam]
    user@beb1# set ethernet connectivity-fault-management maintenance-domain pbbn maintenance-association vlan3350 continuity-check interval 1s
  3. Configure a MEP with the same maintenance association identifier and maintenance domain level (here, vlan3150 and pbbn) and associate them to VLAN 3150 and the pseudo-logical interface cbp0.0).

    [edit protocols oam]
    user@beb1# set ethernet connectivity-fault-management maintenance-domain pbbn maintenance-association vlan3350 mep 100 interface vlan 3350
    user@beb1# set ethernet connectivity-fault-management maintenance-domain pbbn maintenance-association vlan3350 mep 100 interface cbp0.0

    Note: When you configure PBB, a customer backbone port (cbp) pseudo-logical interface is configured for the B-component of the BEB. This permits multiple customer routing instances to be associated with a single PBBN provider routing instance.

  4. Configure the direction in which CFM packets are transmitted for the MEP. Direction up CCMs are transmitted out of every logical interface that is part of the same bridge (here, direction is specified as up).

    [edit protocols oam]
    user@beb1# set ethernet connectivity-fault-management maintenance-domain pbbn maintenance-association vlan3350 mep 100 direction up
  5. Configure automatic discovery to enable the MEP to accept continuity check messages from all remote MEPs of the same maintenance association.

    [edit protocols oam]
    user@beb1# set ethernet connectivity-fault-management maintenance-domain pbbn maintenance-association vlan3350 mep 100 auto-discovery
  6. Configure the continuity check interval for the maintenance association (here, vlan3150). The continuity check protocol is used for fault detection by a MEP. The MEP periodically sends continuity check multicast messages, and receiving MEPs use the CC messages to build a MEP database of all MEPs in the maintenance association.

    [edit protocols oam]
    user@beb1# set ethernet connectivity-fault-management maintenance-domain pbbn maintenance-association vlan3150 continuity-check interval 1s
  7. Configure a MEP with the same maintenance association identifier and maintenance domain level (here, vlan3150 and pbbn).

    [edit protocols oam]
    user@beb1# set ethernet connectivity-fault-management maintenance-domain pbbn maintenance-association vlan3150 mep 100 interface vlan 3350
  8. Configure the direction in which CFM packets are transmitted for the MEP. Direction up CCMs are transmitted out of every logical interface that is part of the same bridge (here, direction is specified as up).

    [edit protocols oam]
    user@beb1# set ethernet connectivity-fault-management maintenance-domain pbbn maintenance-association vlan3150 mep 100 direction up
  9. Configure automatic discovery to enable the MEP to accept continuity check messages from all remote MEPs of the same maintenance association.

    Note: You can also use the command remote-mep to specify a remote MEP.


    [edit protocols oam]
    user@beb1# set ethernet connectivity-fault-management maintenance-domain pbbn maintenance-association vlan3150 mep 100 auto-discovery

set protocols oam ethernet connectivity-fault-management maintenance-domain default-3 mip-half-function default


Step-by-Step Procedure

To configure a MIP for BEB4:

  1. To enable CFM at the B-VLAN level, specify the B-VLAN routing instance name, the B-VLAN ID, and the service group (here, the routing instance is pbn-3-for-eline the B-VLAN IDs are 1200 and 2100, and the service group is eline-svlans):

    [edit protocols oam]
    set ethernet connectivity-fault-management maintenance-domain default-3 virtual-switch pbn-3-for-eline bridge-domain eline-svlans vlan-id 1200
    set ethernet connectivity-fault-management maintenance-domain default-3 virtual-switch pbn-3-for-eline bridge-domain eline-svlans vlan-id 2100
  2. Specify the OAM Ethernet CFM maintenance domain MIP half functions (here, the MIP half function is default):

    [edit protocols oam ]
    user@beb4# ethernet connectivity-fault-management maintenance-domain default-3 mip-half-function default

    Note: Whenever a MIP is configured and a bridge domain is mapped to multiple maintenance domains (MDs) or maintenance associations (MAs), it is essential that the mip-half-function value for all MDs and MAs be the same.

Results

Check the results of the configuration:

user@beb4> show configuration protocols {oam {ethernet {connectivity-fault-management {maintenance-domain default-3 {virtual-switch pbn-3-for-eline {bridge-domain eline-svlans vlan-id [ 1200 2100 ];}mip-half-function default;}}}}}

set protocols oam ethernet connectivity-fault-management maintenance-domain es-domain maintenance-association eline-2 mep 1 auto-discovery

Step-by-Step Procedure

To configure a MEP for ES1:

  1. Configure the maintenance domain es-domain, a mandatory parameter that indicates the nesting relationship between various maintenance domains and is embedded in each of the CFM frames:

    [edit protocols oam]
    user@es1# set protocols oam ethernet ethernet connectivity-fault-management maintenance-domain es-domain level 3
  2. Configure the continuity check interval for the maintenance association (here, vlan3350). The continuity check protocol is used for fault detection by a MEP. The MEP periodically sends continuity check multicast messages, and receiving MEPs use the CC messages to build a MEP database of all MEPs in the maintenance association.

    [edit protocols oam]
    user@es1# set ethernet connectivity-fault-management maintenance-domain es-domain maintenance-association eline-1continuity-check interval 1s
  3. Configure a MEP with the same maintenance domain and maintenance association identifier (here, es-domain and eline-1) and associate them to VLAN 500 and the pseudo-logical interface ge-1/1/0.0.

    [edit protocols oam]
    user@es1# set ethernet connectivity-fault-management maintenance-domain es-domain maintenance-association eline-1 mep 1 interface ge-1/1/0.0
    user@es1# set ethernet connectivity-fault-management maintenance-domain es-domain maintenance-association eline-1 mep 1 interface vlan 500
  4. Configure the direction in which CFM packets are transmitted for the MEP. Direction up CCMs are transmitted out of every logical interface that is part of the same bridge (here, direction is specified as up).

    [edit protocols oam]
    user@es1# set ethernet connectivity-fault-management maintenance-domain es-domain maintenance-association eline-1 mep 1 direction up
  5. Configure automatic discovery to enable the MEP to accept continuity check messages from all remote MEPs of the same maintenance association.

    [edit protocols oam]
    user@es1# set ethernet connectivity-fault-management maintenance-domain pbbn maintenance-association eline-1 mep 1 auto-discovery
  6. Configure the continuity check interval for the maintenance association (here, vlan3150). The continuity check protocol is used for fault detection by a MEP. The MEP periodically sends continuity check multicast messages, and receiving MEPs use the CC messages to build a MEP database of all MEPs in the maintenance association.

    [edit protocols oam]
    user@es1# set ethernet connectivity-fault-management maintenance-domain es-domain maintenance-association eline-2 continuity-check interval 1s
  7. Configure a MEP with the same maintenance domain and maintenance association identifier (here, es-domain and eline-2) and associate them to VLAN 500 and the pseudo-logical interface ge-1/0/3.6.

    [edit protocols oam]
    user@es1# set ethernet connectivity-fault-management maintenance-domain es-domain maintenance-association eline-2 mep 1 interface ge-1/1/0.0
    user@es4# set ethernet connectivity-fault-management maintenance-domain es-domain maintenance-association eline-2 mep 1 interface vlan 600
  8. Configure the direction in which CFM packets are transmitted for the MEP. Direction up CCMs are transmitted out of every logical interface that is part of the same bridge (here, direction is specified as up).

    [edit protocols oam]
    user@es4# set ethernet connectivity-fault-management maintenance-domain es-domain maintenance-association eline-2 mep 1 direction up
  9. Configure automatic discovery to enable the MEP to accept continuity check messages from all remote MEPs of the same maintenance association.

    [edit protocols oam]
    user@es4# set ethernet connectivity-fault-management maintenance-domain es-domain maintenance-association eline-2 mep 1 auto-discovery

Results

Check the results of the configuration:

user@es1> show configuration protocols {oam {ethernet {connectivity-fault-management {maintenance-domain es-domain {level 3;maintenance-association eline-1 {continuity-check {interval 1s;}mep 1 {interface ge-1/1/0.0 vlan 500;direction up;auto-discovery;}}maintenance-association eline-2 {continuity-check {interval 1s;}mep 1 {interface ge-1/1/0.0 vlan 600;direction up;auto-discovery;}}}}}}}

Results

Check the results of the configuration:

user@es4> show configuration protocols {oam {ethernet {connectivity-fault-management {maintenance-domain es-domain {level 3;maintenance-association eline-1 {continuity-check {interval 1s;}mep 2 {interface ge-1/0/3.5 vlan 500;direction up;auto-discovery;}}maintenance-association eline-2 {continuity-check {interval 1s;}mep 2 {interface ge-1/0/3.6 vlan 600;direction up;auto-discovery;}}}}}}}

Verification

To confirm that the configuration is working properly on each router in the PBBN and PBN:

  • Verify that the CC protocol is UP for VLAN 3150 and VLAN 3350 (in the PBBN) and VLAN 500 and VLAN 600 (in the PBN). The MEP should be able to discover remote MEPs in each VLAN.
  • Verify the path between a pair of MEPs using the Linktrace protocol. The MIPs should respond to linktrace messages.

To confirm that the configuration is working properly, perform these tasks:

Verifying CFM on VLAN 3150 in the PBBN

Purpose
