Configuring IP Multicast Routing
Beginning in privileged EXEC mode, follow these steps to configure the sources that are advertised and
the metrics that are used when DVMRP route-report messages are sent:
Command
Step 1
configure terminal
Step 2
access-list access-list-number {deny |
permit} source [source-wildcard]
Step 3
interface interface-id
Step 4
ip dvmrp metric metric [list
access-list-number] [[protocol process-id]
| [dvmrp]]
Step 5
end
Step 6
show running-config
Step 7
copy running-config startup-config
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.
78-11194-03
Purpose
Enter global configuration mode.
Create a standard access list, repeating the command as many times as
necessary.
•
For access-list-number, the range is 1 to 99.
•
The deny keyword denies access if the conditions are matched. The
permit keyword permits access if the conditions are matched.
•
For source, enter the number of the network or host from which the
packet is being sent.
•
(Optional) For source-wildcard, enter the wildcard bits in dotted
decimal notation to be applied to the source. Place ones in the bit
positions that you want to ignore.
Recall that the access list is always terminated by an implicit deny
statement for everything.
Enter interface configuration mode, and specify the interface connected
to the MBONE and enabled for multicast routing.
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.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
