Monitoring VPLS
This section describes the following tasks to manage and monitor a VPLS configuration:
- Setting Statistics Baselines
- Clearing the VPLS Forwarding Table
- Clearing BGP Attributes
- Monitoring Bridging-Related Settings for VPLS
- Monitoring BGP-Related Settings for VPLS
- Monitoring LDP-Related Settings for VPLS
- Monitoring MPLS-Related Settings for VPLS
- Monitoring VPLS-Specific Settings
Setting Statistics Baselines
You can use the following baseline commands to set a statistics baseline for a VPLS instance, for a network interface associated with a VPLS instance, or for the VPLS virtual core interface associated with a VPLS instance. The router implements the baseline by reading and storing the statistics at the time the baseline is set and then subtracting this baseline whenever baseline-relative statistics are retrieved.
baseline bridge
host1#baseline bridge vplsA
baseline bridge interface
- Use to set a statistics baseline for a particular network interface associated with a VPLS instance.
- You must specify the following:
- interfaceType—One of the following interface types listed in Interface Types and Specifiers in JUNOSe Command Reference Guide, About This Guide:
- interfaceSpecifier—Particular interface; format varies according to interface type; see Interface Types and Specifiers in JUNOSe Command Reference Guide, About This Guide for information
host1#baseline bridge interface gigabitEthernet 4/1
baseline bridge interface vpls
- Use to set a statistics baseline for the VPLS virtual core interface associated with a VPLS instance.
- Example
host1#baseline bridge interface vpls vplsA
Clearing the VPLS Forwarding Table
You can use the following clear commands to remove all dynamic (learned) MAC address entries or a specific MAC address entry from the forwarding table for a VPLS instance.
clear bridge
- Use to remove from the forwarding table all dynamic MAC address entries for the specified VPLS instance.
- Example
host1#clear bridge vplsB
clear bridge address
- Use to remove from the forwarding table a specific dynamic MAC address entry for the specified VPLS instance.
- Example
host1#clear bridge vplsB address 0090.1a40.9992
clear bridge interface
- Use to remove from the forwarding table all dynamic MAC address entries for a network interface associated with a VPLS instance.
- You must specify the following:
- interfaceType—One of the following interface types listed in Interface Types and Specifiers in JUNOSe Command Reference Guide, About This Guide:
- interfaceSpecifier—Particular interface; format varies according to interface type; see Interface Types and Specifiers in JUNOSe Command Reference Guide, About This Guide for information
host1#clear bridge interface atm 3/3.2
clear bridge interface vpls
- Use to remove from the forwarding table all dynamic MAC address entries for the VPLS virtual core interface associated with a VPLS instance.
- Example
host1#clear bridge interface vpls vplsA
Clearing BGP Attributes
You can use the clear ip bgp commands listed in Table 55 to clear BGP attributes for the L2VPN address family and, in one case, for the VPLS address family associated with a specific VPLS instance.
For more information about using these commands, see Chapter 1, Configuring BGP Routing. For information about the syntax of each command, see the JUNOSe Command Reference Guide A to M.
Monitoring Bridging-Related Settings for VPLS
You can use the show commands listed in Table 56 to display VPLS settings related to transparent bridging. Except for the show bridge interface vpls command, which is only for VPLS instances, you can use these commands to monitor both VPLS instances and standard bridge groups for transparent bridging. The examples in this section show those portions of the command display relevant to a VPLS configuration.
For more information about using these commands, see Monitoring Transparent Bridging in JUNOSe Link Layer Configuration Guide, Chapter 10, Configuring Transparent Bridging. For information about the syntax of each command, see the JUNOSe Command Reference Guide N to Z.

- Remote PE—IP address of the remote VPLS edge (VE) router, which is analogous to the remote provider edge (PE) router in a BGP/MPLS VPN configuration
- In-label—Incoming MPLS label from the remote site
- Out-label—Outgoing MPLS label used to reach the remote site
- MPLS NH Idx—MPLS next-hop index number that corresponds to the outgoing MPLS label
- Up-down Time—Time since the last state change for this VPLS connection
