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:
•
Tunnels cannot be removed if they are being used as templates.
•
This feature does not support mobile routers that are acting as mobile nodes.
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
! If prompted
wd#
configure terminal
wd(config)#
ip multicast-routing
! Enables 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
! Enables Protocol Independent Multicast (PIM)
on the tunnel interface in sparse mode.
wd(config)#
exit
wd(config)#
router mobile
! Enables Mobile IP on the router.
wd(config)#
ip mobile mobile-networks
! Configures mobile networks for the mobile host
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)#
