Monitoring and Maintaining DVMRP

Monitoring and Maintaining DVMRP

To clear routes from the DVMRP routing table, use the following command in EXEC mode:

Command	Purpose
Router# clear ip dvmrp route { * route}	Deletes routes from the DVMRP routing table.

To display entries in the DVMRP routing table, use the following command in EXEC mode:

Command	Purpose
Router# show ip dvmrp route [name ip-address	Displays the entries in the DVMRP routing table.
type number]

DVMRP Configuration Examples

This section provides the following DVMRP configuration examples:

•DVMRP Interoperability Example

•DVMRP Tunnel Example

DVMRP Interoperability Example

The following example configures DVMRP interoperability for configurations when the PIM router and the DVMRP router are on the same network segment. In this example, access list 1 advertises the networks (198.92.35.0, 198.92.36.0, 198.92.37.0, 131.108.0.0, and 150.136.0.0) to the DVMRP router, and access list 2 is used to prevent all other networks from being advertised (the ip dvmrp metric 0 interface configuration command).

ip address 131.119.244.244 255.255.255.0 ip pim dense-mode

access-list 1 permit 198.92.35.0 0.0.0.255 access-list 1 permit 198.92.36.0 0.0.0.255 access-list 1 permit 198.92.37.0 0.0.0.255 access-list 1 permit 131.108.0.0 0.0.255.255 access-list 1 permit 150.136.0.0 0.0.255.255 access-list 1 deny 0.0.0.0 255.255.255.255 access-list 2 permit 0.0.0.0 255.255.255.255
