Chapter 44 Configuring IP Multicast Routing
Configuring Basic DVMRP Interoperability Features
To disable the metric or route map, use the
no
ip dvmrp metric
metric
[
list
access-list-number
]
[[
protocol process-id
] | [
dvmrp
]] or the
no ip dvmrp metric
metric
route-map
map-name
interface
configuration command.
A more sophisticated way to achieve the same results as the preceding command is to use a route map
(
ip dvmrp metric
metric
route-map
map-name
interface configuration command) instead of an access
list. You subject unicast routes to route-map conditions before they are injected into DVMRP.
This example shows how to configure DVMRP interoperability when the PIM device and the DVMRP
router are on the same network segment. In this example, access list 1 advertises the networks
(198.92.35.0, 198.92.36.0, 198.92.37.0, 131.108.0.0, and 150.136.0.0) to the DVMRP router, and access
list 2 prevents all other networks from being advertised (
ip dvmrp metric 0
interface configuration
command).
Switch(config-if)#
interface gigabitethernet1/0/1
Switch(config-if)#
ip address 131.119.244.244 255.255.255.0
Switch(config-if)#
ip pim dense-mode
Switch(config-if)#
ip dvmrp metric 1 list 1
Switch(config-if)#
ip dvmrp metric 0 list 2
Switch(config-if)#
exit
Switch(config)#
access-list 1 permit 198.92.35.0 0.0.0.255
Switch(config)#
access-list 1 permit 198.92.36.0 0.0.0.255
Switch(config)#
access-list 1 permit 198.92.37.0 0.0.0.255
Switch(config)#
access-list 1 permit 131.108.0.0 0.0.255.255
Switch(config)#
access-list 1 permit 150.136.0.0 0.0.255.255
Switch(config)#
access-list 1 deny 0.0.0.0 255.255.255.255
Switch(config)#
access-list 2 permit 0.0.0.0 255.255.255.255

] [[

]
| [
dvmrp
]]
Configure the metric associated with a set of destinations for DVMRP
reports.
•
For
metric
, the range is 0 to 32. A value of 0 means that the route
is not advertised. A value of 32 is equivalent to infinity
(unreachable).
•
(Optional) For
list
access-list-number
, enter the access list number
created in Step 2. If specified, only the multicast destinations that
match the access list are reported with the configured metric.
•
(Optional) For
protocol process-id
, enter the name of the unicast
routing protocol, such as
eigrp
,
igrp
,
ospf
,
rip
,
static
, or
dvmrp
,
and the process ID number of the routing protocol. If specified,
only routes learned by the specified routing protocol are advertised
in DVMRP report messages.
•
(Optional) If specified, the
dvmrp
keyword allows routes from the
DVMRP routing table to be advertised with the configured
metric
or filtered.
