disable-dynamic-redistribute
• Use to halt the dynamic redistribution of routes that are initiated by changes to a route
map; dynamic redistribution is enabled by default.
• Example
host1(config-router)#disable-dynamic-redistribute
• There is no no version.
• See disable-dynamic-redistribute.
Exchanging DVMRP Unicast Routes
DVMRP maintains its own unicast routing table, based on distance vector calculations.
The routing table defines the best-known distance to each destination and how to get
there. The router updates the table by exchanging information with its neighbors. The
DVMRP routing table is used solely for RPF lookups.
By default, if DVMRP owns an interface, that interface exchanges DVMRP unicast routes
with its neighbors, and you cannot disable the exchange of routes. However, you can
enable and disable the exchange of DVMRP unicast routes on interfaces that DVMRP
does not own.
When an interface exchanges DVMRP routes, the router obtains routes from DVMRP
report messages and stores them in its DVMRP routing table. Other multicast protocols,
such as PIM, can then use these routes for RPF lookups. With this feature, PIM can use
the DVMRP routing table even when the router is not running DVMRP.
All interfaces, including tunnels, support DVMRP unicast routing. DVMRP tunnels use
DVMRP multicast routing to support DVMRP unicast routing.
ip dvmrp unicast-routing
• Use to enable the exchange of DVMRP unicast routes on an interface not owned by
DVMRP.
• Example
host1:boston(config-if)#ip dvmrp unicast-routing
• Use the no version to disable the exchange of DVMRP unicast routes on an interface
not owned by DVMRP.
• See ip dvmrp unicast-routing.
Disabling and Removing DVMRP
You can disable DVMRP on a VR or an interface without removing the configuration. You
can also remove DVMRP from a VR or an interface.
