Ipv6 Mroute

Se desplega el siguiente escenario.

R6-R4-R5

Entre ellos no tienen la ruta RPF correcta hacia el RP y BSR que es el R6.
Para que funcione el enrutamiento estático debe colocarse la interfaz y la dirección IP. Si solo se coloca uno de ellos no funciona y genera error de RPF Failed. Se puede observar con el comando debug ipv6 pim bsr.

En el escenario anterior, se debe usar una ruta estática, para que aprenda la ruta hacia el BSR. La ruta apunta hacia R4, pero no se coloca el IP, solo la interfaz:

Rack1R5(config)#ipv6 route 2001:130:1:6::/64 2001:130:1:45::4 multicast
Rack1R5#show ipv6 rpf 2001:130:1:6::6

Para que funcione, tienen que estar la interfaz y la dirección:

Rack1R5(config)# ipv6 route 2001:130:1:6::/64 FastEthernet0/1.45 2001:130:1:45::4 multicast
