Could you give us more information about this topology:
The fact that you receive packtes with that source does not influence your
capacity to do a L2/L3 resolution.
This could be a frame-relay map issue or any other problem related to this
L2/L3.
Try this: R1 - R2 over a multipoint frame-relay, no inverse-arp, map only on
R1. check if you have the same behaviour.
*Mar 1 01:44:42.563: IP: s=10.0.200.2 (Ethernet0/0), d=224.0.0.9, len 132,
rcvd 2
*Mar 1 01:44:42.567: UDP src=520, dst=520
*Mar 1 01:44:43.151: IP: tableid=0, s=10.0.100.1 (local),
d=10.0.100.2(Serial1/0), routed via RIB
*Mar 1 01:44:43.151: IP: s=10.0.100.1 (local), d=10.0.100.2 (Serial1/0),
len 100, sending
*Mar 1 01:44:43.155: ICMP type=8, code=0
*Mar 1 01:44:43.155: IP: s=10.0.100.1 (local), d=10.0.100.2 (Serial1/0),
len 100, encapsulation failed
*Mar 1 01:44:43.159: ICMP type=8, code=0.
So, please let us know more details on this.
