Draft-Rosen Multicast VPNs Examples

This section contains configuration examples and commands you can issue to verify your draft-rosen IPv4 multicast configuration:

Example: Basic IPv4 Multicast over a Layer 3 VPN Configuration

Figure 81: Basic IPv4 Multicast over a Layer 3 VPN Topology Diagram

Image g017220.gif

In Figure 81, the multicast source sends to group 229.1.1.1, and the receiver listens to the same group address. The VPN C-RP is located at Router CE1, whereas the SP-RP is located at Router P0. The routing instances are named VPN-A on both routers PE0 and PE1.

Router CE0

[edit]
protocols {
pim {
rp {
dense-groups {
229.0.0.0/8;
}
static {
address 10.254.245.91;
}
}
interface all {
mode sparse-dense;
version 2;
}
interface fxp0.0 {
disable;
}
}
}

In this example, the interface all statement is configured. If the topology requires only a few interfaces to be configured for PIM, then loopback interface lo0 must also be one of the configured interfaces.

Router PE0

[edit]
protocols {
pim {
rp {
static {
address 10.254.71.47;
}
}
interface all {
mode sparse;
version 2;
}
interface fxp0.0 {
disable;
}
}
}

Router PE0 also requires a standard VPN configuration, along with the PIM instance configuration. The vpn-group-address command is the only new PIM statement with PIM used exclusively with a routing instance multicast configuration.

[edit]
routing-instances {
VPN-A {
instance-type vrf;
interface t1-0/3/0:0.0;
interface lo0.1
route-distinguisher 10.254.71.46:100;
vrf-import VPNA-import;
vrf-export VPNA-export;
protocols {
ospf {
export bgp-to-ospf;
area 0.0.0.0 {
interface t1-0/3/0:0.0;
interface lo0.1;
}
}
pim {
dense-groups {
229.0.0.0/8;
}
vpn-group-address 239.1.1.1;
rp {
static {
address 10.254.245.91;
}
}
interface t1-0/3/0:0.0 {
mode sparse-dense;
version 2;
}
interface lo0.1 {
mode sparse-dense;
version 2;
}
}
}
}
}

Router P0

[edit]
protocols {
pim {
rp {
local {
address 10.254.71.47;
}
}
interface all {
mode sparse;
version 2;
}
interface fxp0.0 {
disable;
}
}
}

Again, if the configuration calls for specific interfaces to be configured for PIM, loopback interface lo0 must be included as one of the interfaces running PIM.

Verifying Your Work

To verify correct operation of basic IPv4 multicast over a Layer 3 VPN, use the following commands:

The following sections show the output of these commands used with the configuration example:

RP Information

You can view PIM information for the master instance with the show pim command. You can see information on the PIM routing instance with the show pim (rps | join extensive) instance instance-name command. Output verifying the SP-RP (10.254.71.47) as well as the VPN C-RP (10.254.245.91) follows.

PIM Information Prior to Multicast Transmission

With the configuration properly set, the backbone PIM sessions should be established before any traffic is forwarded. In the output below, the routers were configured, but the traffic source was not transmitting and the receiver was not requesting to be part of a group. Notice that there is no PIM join information for the routing instances yet.

Successful PIM Join Verification

In the remaining output for this example, the show pim join output shows group participation. Also displayed is the output from the show multicast route extensive and show multicast next-hop commands. The join output for PIM within a VPN will reference the group 229.1.1.1, while the service provider side of the network will reference the join information for group 239.1.1.1 (which is the VPN group ID). In the show multicast route extensive output, you can view the group, sender, and upstream interface toward the sender.

Example: IPv4 Multicast with Interprovider VPNs Configuration

Figure 82: IPv4 Multicast with Interprovider VPNs Topology Diagram

Image g017131.gif

Interprovider VPNs are also mentioned in RFC 4364. An example is shown in Figure 82. The topology is slightly different; the main difference is the addition of MSDP between the two provider core transit (P) routers. In this limited topology, each P router is an SP-RP for the local autonomous system (AS), and Router CE1 is the VPN C-RP. VPN-A is the name of the routing instance on routers PE0 and PE1.

Verifying Your Work

The show commands used to verify proper functionality of multicast in an interprovider environment are the same ones used with the first Layer 3 VPN multicast example (see Verifying Your Work).
