Multicast over Tunnel

July 22, 2008 @ 6:09 pm · Filed under CCIE Study

Hafiz,
A gre tunnel will do the trick. However it will create an RPF failure so you will have to add a static mroute, unless you scenario allows for dynamic routing protocols over the tunnel. For example on R1
int t0 ip add 10.10.10.1 255.255.255.0
On R4: int t0 ip add 10.10.10.2 255.255.255.0 ip pim sparse-mode exit ip mroute 0.0.0.0 0.0.0.0 10.10.10.1
Sincerely,
Bill
