Configuring RPL Policies in Receiver VRFs on Source PE Routers to Propagate Joins to a Source VRF: Example
In addition to configuring route targets , RPL policies can be configured in receiver VRFs on a ource PE
router to propagate joins to a specified source VRF. However, this configuration is optional.
The configuration below shows a policy in which the receiver VRF can select either “provider_vrf_1” or
“provider_vrf_2” to propagate PIM joins. Provider_vrf_1 will be selected if the rendezvous point (RP) for a
multicast stream is 201.22.22.201, while provider_vrf_2 will be selected if the RP for a multicast stream is
202.22.22.201.
As an alternative, you can configure a multicast group-based policy as shown in the Configuring RPL Policies
in Receiver VRFs to Propagate Joins to a Source VRF: Example, on page 162.
route-policy extranet_streams_from_provider_rp
if source in (201.22.22.201) then
set rpf-topology vrf provider_vrf_1
else if source in (202.22.22.201) then
set rpf-topology vrf provider_vrf_2
else
pass
endif
