Tunnel Templates; Applying The Tunnel Template On The Home Agent - Cisco C3201FESMIC-TP= - 3201 Fast EN Switch Mobile Interface Card Expansion Module Software Configuration Manual

Tunnel Templates

Tunnel templates allow a mobile router to carry multicast sessions to mobile networks as it roams. The
Tunnel Templates for Multicast feature allows the configuration of multicast sessions on statically
created tunnels to be applied to dynamic tunnels brought up on a home agent and a mobile router. A
tunnel template is defined and applied to the tunnels between the home agent and the mobile router.
Reverse tunneling must be enabled from the mobile router to the home agent.
The following restrictions apply:

Applying the Tunnel Template on the Home Agent

To apply the tunnel template to the tunnels brought up at the home agent, use the interface tunnel
command. For example:
wd>enable
wd> password
wd#configure terminal
wd(config)#ip multicast-routing
wd(config)#interface tunnel interfacenumber ! Designates a tunnel interface and enters
interface configuration mode. This is the tunnel template that will be applied to the
mobile networks.
wd(config-in)#ip pim sparse-mode
on the tunnel interface in sparse mode.
wd(config)#exit
wd(config)#router mobile
wd(config)#ip mobile mobile-networks
and enters mobile networks configuration mode.
wd(config)#tunnel template interfacenumber ! Designates the tunnel template to apply during
registration. The interfacenumber argument is set to the tunnel template.
wd(config)#end
