Hello,

You won't be able to ping 224.11.11.11.from routerA unless:
1. ip multicast-routing is enabled on routerA
2. "ip pim dense" is configured on routerA FastEthernet0/0.

HTH,
Alex

Subject: Help with MVR config

Hi,

I am trying to practice MVR and be able to ping the subscribers. I've
struggles for hours and still couldn't get ping response. Can someone
look at my config and see if it's missing something? -Thanks a lot!

Topology:
RouterA---Cat3550---RouterB
        vlan50 vlan11

The purpose is to be able to ping 224.11.11.11 from routerA and get
responses.
IP multicast-routing is disabled on cat3550, enabled on routerA & B.

routerA-
interface FastEthernet0/0
 ip address 172.16.50.4 255.255.255.0 <--trying to ping 224.11.11.11
from this interface

Cat3550-
mvr vlan 50
mvr
mvr mode dynamic
mvr group 224.11.11.11
interface FastEthernet0/2 <-- to RouterB
 description MR2
 switchport access vlan 11
 switchport mode access
 mvr type receiver
 mvr vlan 50 group 224.11.11.11
interface FastEthernet0/3 <-- to RouterA
 switchport access vlan 50
 switchport mode access
 mvr type source
 mvr vlan 50 group 224.11.11.11

interface Vlan11
 ip address 172.16.11.10 255.255.255.0
 
end
interface Vlan50
 ip address 172.16.50.10 255.255.255.0
 ip pim dense-mode

RouterB-
interface FastEthernet0/0 <-- port to cat3550
 ip address 172.16.11.3 255.255.255.0
 no ip route-cache
 ip igmp join-group 224.11.11.11
 no ip mroute-cache
 duplex auto
 speed auto

Some mvr related output here, I couldn't see anything wrong. :-(
