In this post, we'll take a look expanding on from Profile 3 and leveraging BGP as the PE-CE customer signaling mechanism rather than PIM. PIM is still enabled on the PE-CE link as is IGMPv3 and in the customer and provider network. But rather than PIM signaling, BGP is used to communicate the different messages across the network. We'll see a few new route types we haven't seen before. Type 6 which indicates a Shared Tree Join, Type 7 which indicates a Source Tree Join and Type 5 which indicates a PE that connects to the customer source.
The configuration is relatively straightforward, we'll configure both IOS XE and IOS XR, however XRv 6.0 doesn't seem to work in the control plane or data plane. Despite following the configuration guide for Profile 11 via XR, it doesn't seem to work. Attempting a reload didn't fix the issue either.
R1, R3 and R7
vrf definition MVPN
address-family ipv4
mdt auto-discovery pim
mdt overlay use-bgp
XR1
router pim
vrf CORE
address-family ipv4
rpf topology route-policy RPL_PROFILE_3
mdt c-multicast-routing bgp
The above configuration is straightforward, on IOS and XR, BGP is used for the c-multicast-routing, IOS states use BGP as the overlay and XR uses BGP for customer multicast signaling. I showed the Profile 3 applicable configurations, the PIM auto discovery and PIM RPL application. Once the configuration is in place, the PE routers begin populating Type 6 routes in the IPv4 MVPN BGP table. Type 6 routes indicate the customer signaled to receive ASM traffic, which is what Type 6 routes indicate.

The above outputs show that the R1, R3 and R7 have signaled Type 1 routes and Type 6 routes, however the Type 6 routes show a next hop of 0.0.0.0, this means that multicast traffic hasn't been sent yet.
