mcast question

I have a cat5500 with an RSM and several vlans that I'm trying to use to multicast video from an IP/TV server cluster. I think I have the switch and RSM configured properly, but the RSM won't forward the IGMP membership report packets from the client vlan to the server vlan. I have igmp enabled on the cat:

#igmp

set igmp fastleave enable

!

and here's relevant config from the RSM:

ip multicast-routing

!

interface Vlan60

description SON vlan60: User60

ip address 10.2.60.8 255.255.255.0

no ip redirects

no ip directed-broadcast

ip pim sparse-mode

no ip route-cache cef

no ip mroute-cache

mls rp vtp-domain SON

mls rp ip

standby 1 priority 100 preempt

standby 1 ip 10.2.60.10

!

interface Vlan120

description SON vlan120: 4th-labs

ip address 10.1.120.8 255.255.255.0

no ip redirects

no ip directed-broadcast

ip pim sparse-mode

no ip route-cache cef

ip cgmp

no ip mroute-cache

mls rp vtp-domain SON

mls rp ip

standby 1 priority 100 preempt

standby 1 ip 10.1.120.10

!

Any help would be appreciated.

Re: mcast question

PIM Sparse mode requires a "Rendevous Point" (RP). Sparse-Dense will run in dense mode if an RP is not found.

You can either assign one, or set up a vote to auto-create one.

Check out:

IP PIM SEND-RP-ANNOUNCE

IP PIM RP-ADDRESS

and if you're using PIM V.2:

IP PIM BSR-CANDIDATE

(bsr is Boot Strap Router)

Good Luck

Scott
