Re: GRE Tunnel - one way ?

Thank you for your response. I think I am very close ... but ...

I tried but without a "tunnel source" the tunnel interface on Router B
does not come up. Here is a snippet of my configuration on Routers A
and B ..

I can tell from the Router A serial interface stats connected to the
one-way link that my multicast packets are getting tunnelled and are
going through to the one way link....

Router B is receiving it on its serial link but the packets as
evidenced by the serial interface statistics. However it never get
de-capsulated and forwarded on the LAN of ROuter B.
