Hi Angelo,
Yes mine also wouldn't ping from the serial interface of the spoke. I don't
think there would be many scenarios where you would need to be able to snd
multicast traffic from there but to allow this through I think you would
need to put another mroute statement on the hub because the RPF wont allow
traffic sourced on that same logical subnet to go in and out that same
interface...
E.g.
Ip mroute 149.1.123.1 255.255.255.255 149.1.123.1
Don't take my word for it though, please try it out since I'm only just now
starting to think I understand it and am probably wrong ;-)
Peter

Hi Sabrina, Peter,
I tried doind the config that Sabrina posted. I did it one by one. All
ping are ok. I could not explain why I can't do extended ping on poke2. Am I
missing something? Or I am getting the RPF issue that Peter had? Sorry I am
totally lost here.
