Hey Guys,
I have a Cisoc 2821 (rescued from the garbage) in my lab with 2 physical interfaces. We'll call this router "P"
Each physical interface on router "P" has no config, but has 3 802.1q under it and is plugged into a switch that allows trunking to these vlans. All BGP/routing/unicast works as expected between router "P" (simulated provider) and router "E" (simulated customer - our on-site router)
On router P (interfaces Gi0/0, and Gi0/1)
Gi0/0 has no config but Gi 0/0.1, Gi0/0.2, Gi0/0.3 all have config and are assigned to vrf "c"
Gi0/1 also has no config but Gi0/1.4, Gi0/0.5, Gi0/0.6 all have config & are assigned to vrf "s"
I've got these 2 vrfs to emulate 2 provider networks. Both vrfs run BGP & multicast (pim sparse mode, with autorp)
Gi0/0.1 goes to router E and does BGP
Gi0/1.4 also goes to router E and does BGP
As far as router E is concerned, it's talking to 2 different networks.
Multicast routing is turned on for both vrfs (Router P) & config is the same for both. Auto RP is also enabled as is pim-sparse mode for both interfaces on router E as well as router P.
vrf c works great & it finds the RP.
vrf s never finds an RP.
I've shut down the working vrf c parent interface (Gi0/0) just incase it was some RPF bug or something, but it still doesn't work.
Anyone seen this? I'm almost convinced this is a bug...
