dvmrp fails after serial link resets at CIsco-2500

Have enabled dvmrp on serial 0 for forwarding multicast packets. on cisco 2503 series. once the serial link resets, the multicast packets are not forwarded until and unless a igmp join on the serial is given once again even though the command already exists. The multicast receive end router is a dvmrp enabled router. Any help?

A few questions:

1. What IOS version are you running?

2. Where is the multicast source located?

IOS version is 11.3(3)

The mulitcast source is connected to the e0 interface router

igmp-join has been given on both e0 and s0

dvmrp unicast-routing is enabled at s0

pim is enabled at both e0 and s0

Once the serial link goes off and comes up, the mroute for the source shows to be pruned with outgoing interface as null which should have been serial0
