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.

To specify the DVMRP routes for an interface to advertise:

• Issue the ip dvmrp announce-filter in Interface Configuration mode.
  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.
