Ok so I'm official stuck
Trying to complete 5.3 in Vol3 lab7 but seem to be having some intermittent
failures.
Specifically, multicast pings between MSDP peers seems to fail. I say
seems, because they work pretty reliably the first time, but if I try
subsequent times they fail.
Right now I am testing from R4 pinging 239.0.0.2 (on R2). R5 and R1 are
setup as MSDP peers.
All routers mentioned above are running sparse-mode
Here's a tidbit of output:
R4#ping 239.0.0.2
Type escape sequence to abort.
Sending 1, 100-byte ICMP Echos to 239.0.0.2, timeout is 2 seconds:
Reply to request 0 from 12.1.2.2, 96 ms

Any suggestions, or troubleshooting ideas would be appreciated. Thanks
