Configuring RPL Policies in Receiver VRFs to Propagate Joins to a Source VRF: Example
In addition to configuring route targets, Routing Policy Language (RPL) policies can be configured in
receiver VRFs on receiver PE routers to propagate joins to a specified source VRF. However, this
configuration is optional.
The following configuration example shows a policy where the receiver VRF can pick either
“provider_vrf_1” or “provider_vrf_2” to propogate PIM joins.
In this example, provider_vrf_1 is used for multicast streams in the range of from 227.0.0.0 to
227.255.255.255, while provider_vrf_2 is being used for streams in the range of from 228.0.0.0 to
228.255.255.255.
