Specifying Routes to Be Advertised

By default, if DVMRP owns an interface, that interface advertises all DVMRP routes it has learned to its neighbors. You can specify the routes that the interface advertises by issuing the ip dvmrp announce-filter command in conjunction with a standard IP access list. The IP access list defines the DVMRP routes that are advertised.

ip dvmrp announce-filter

• Use to specify the DVMRP routes for an interface to advertise.
• Specify a standard IP access list of routes for the interface to advertise.
• Example

  host1:boston(config-if)#ip dvmrp announce-filter boston-list

• Use the no version to enable the interface to advertise all DVMRP routes that it has learned.
• See ip dvmrp announce-filter.
