Configuring IP Multicast Routing
Configuring IP Multicast Routing
DETAILED STEPS
To remove a filter on incoming RP announcement messages, use the no ip pim rp-announce-filter rp-list
access-list-number [group-list access-list-number] global configuration command.
Command Purpose
1. configure terminal Enter global configuration mode.
2. ip pim rp-announce-filter rp-list
access-list-number group-list
access-list-number
Filter incoming RP announcement messages.
Enter this command on each mapping agent in the network.
Without this command, all incoming RP-announce messages
are accepted by default.
For rp-list access-list-number, configure an access list of
candidate RP addresses that, if permitted, is accepted for the
group ranges supplied in the group-list access-list-number
variable. If this variable is omitted, the filter applies to all
multicast groups.
If more than one mapping agent is used, the filters must be
consistent across all mapping agents to ensure that no
conflicts occur in the Group-to-RP mapping information.
3. access-list access-list-number
{deny | permit} source
[source-wildcard]
Create a standard access list, repeating the command as
many times as necessary.
 For access-list-number, enter the access list number
specified in Step 2.
 The deny keyword denies access if the conditions are
matched. The permit keyword permits access if the
conditions are matched.
 Create an access list that specifies from which routers and
multilayer switches the mapping agent accepts candidate
RP announcements (rp-list ACL).
 Create an access list that specifies the range of multicast
groups from which to accept or deny (group-list ACL).
 For source, enter the multicast group address range for
which the RP should be used.
 (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.
4. end Return to privileged EXEC mode.
5. show running-config Verify your entries.
6. copy running-config startup-config (Optional) Save your entries in the configuration file.
