Re: MCast GRE Tunnel

Hi Rob,

In case if ASBR connection is PPP / Frame-relay, remote host ip (/32) is
installed in the local routing table. This cause me RPF failure (while
forwarding mcast traffic out of tunnel) if I use Serial interface IP for
Tunnel.

I couldn't succeed by using loopback ip as well, but still couldn't figure
out the root cause for that....

Regards,
John
