Configuring IP Routing
CLI Command To configure the DVMRP In terface using the CLI:

(configure-if:<interface>)# ip dvmrp <options>

Interface Type Select an Interface type. You can configure the interface
type as:
• Broadcast - All traffic is forwarded through the
routers. This is not a tunnel and does not require
encapsulation.
• Non-Encapsulated Tunnel - All multicast data
traffic is IPIP encapsulated, but the protocol
messages are unicast.
• IPIP Tunnel - All multicast traffic (data and
protocol messages) are encapsulated in IP unicast
packets with the protocol set to IPIP (IP in IP).
Tunnel Endpoint
Address Displays the Tunnel endpoint IP address of a router.
You can modify this setting to represent the end router
IP address to which you want to send datagrams
through a tunnel. The origin and endpoint routers are
separated by a gateway(s) or a router(s) that do not
support DVMRP.
Interface Metric Displays the Cost metric for the interface.
The valid range for this field is 1 to 31. The default
setting is 1.
Src Host Addr in
Prune Msg Select Disable to send prune messages with only the
subnet portion of the source address.
The default is Enable (sends prune messages with the
full source host address).
Interface Scope Select the minimum TTL (time-to-live) required for a
packet to leave this interface. The options are None,
127, and 255.
