For example, the following command creates a DVMRP unicast accept policy

named “dvmrppol3”:

dvmrp# unicast-accept dvmrppol3

unicast-accept/dvmrppol3/dvmrp#

To customize a DVMRP unicast accept policy, set one or more of the following

parameters (Table 4-4

Table 4-4. DVMRP Unicast Accept Policy BCC Parameters

Parameter Values (d = default) Description

action accept (d)

ignore Specifies whether to accept or ignore the interfaces or networks

for a route that matches this policy.

• To import the matching route from the IP unicast routing table

to the DVMRP routing table, specify accept.

• If you do not want to import the matching route, specify ignore.

inject null (d)

list of IP addresses and

masks

Specifies a list of IP networks that DVMRP injects into the DVMRP

routing table in place of the advertised networks. This parameter

has meaning only if the action is set to accept.

To inject the advertised network, use the default, null. Use this

parameter to insert an aggregate or default network along with the

actual network.

interface null (d)

IP address

To apply the DVMRP unicast accept policy to advertisements that

arrive on any interface, use the default, null. Otherwise, this

parameter specifies the IP address of an interface that can

receive DVMRP unicast updates to accept or ignore.

metric 1 (d) through 31 Specifies the cost of the route that DVMRP injects into the

DVMRP routing table

network

address mask

match exact

match

range

Specifies the networks that match this policy, and whether you

want the match to be exact or a range.

•

match exact

means match the specific network

advertisement (number and mask).

•

match range

means match any network number that falls in

the range indicated by the IP address and mask.

precedence 0 (d) through

2,147,483,647

Specifies a metric that DVMRP uses to compare this policy to

other policies that match the route. DVMRP uses the precedence

value to choose among multiple matches.

In ranking policies according to precedence, keep in mind that the

route with the highest value is the preferred route. In case of a tie,

the most recent route wins.
