Routing Access Policies for DVMRP
The access policy capabilities for DVMRP resemble those for RIP.
If the DVMRP protocol is used for routing IP multicast traffic, you
can configure the switch to use an access profile to determine:
• Trusted Neighbor—Use an access profile to determine trusted
DVMRP router neighbors for the VLAN on the switch running
DVMRP. To configure a trusted neighbor policy, use this
command:
configure dvmrp vlan [<name> | all] trusted-
gateway [<access_profile> | none]
• Import Filter—Use an access profile to determine which
DVMRP routes are accepted as valid routes. To configure an
import filter policy, use this command:
configure dvmrp vlan [<name> | all] import-
filter [<access_profile> | none]
