Mixing auto-rp and static rp domains

I am currently experiencing a problem with multicast.

We have 2 separate multicast domains. 1 is statically assigned and the other uses auto-rp.

At the border of the 2 domains I am only able to receive multicast traffic from the static side to the auto-rp side.

The rp on the auto-rp is the next hop router for the border router.

Here is what the auto-rp RP says about the stream in question..

(*, 237.111.0.117), 00:05:44/stopped, RP 10.250.11.1, flags: S

Incoming interface: Null, RPF nbr 0.0.0.0

Outgoing interface list:

Vlan21, Forward/Sparse-Dense, 00:05:44/00:02:45, H

(10.107.3.2, 237.111.0.117), 00:05:44/00:03:27, flags: T

Incoming interface: Vlan10, RPF nbr 192.168.252.18

Outgoing interface list:

Vlan21, Forward/Sparse-Dense, 00:05:44/00:02:45, H

(192.168.240.198, 237.111.0.117), 00:05:22/00:01:44, flags: PT

Incoming interface: Vlan21, RPF nbr 10.250.11.3

Outgoing interface list: Null

10.107.3.2 is coming from the static side and works. 192.168.240.198 is coming from the auto-rp side and does not forward to the static side. As you can see it is pruned.

Both domains use different shared trees since they are connected to different RPs. Is this feasible or must we go to 1 RP or can we convert the border router to a dense-mode sender?

Re: Mixing auto-rp and static rp domains

Brian,

Are you running MSDP between the RPs in the two domains?
