DETAILED STEPS
PurposeCommand or Action
Enters the global configuration mode.configure terminal
Example:
Switch# configure terminal
Step 1
Filters incoming RP announcement messages.ip pim rp-announce-filter rp-list
access-list-number group-list
access-list-number
Step 2
Enter this command on each mapping agent in the network. Without this
command, all incoming RP-announce messages are accepted by default.
Example:
Switch(config)# ip pim
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.
rp-announce-filter rp-list 10
group-list 14
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.
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.
Note
Creates a standard access list, repeating the command as many times as
necessary.
access-list access-list-number {deny |
permit} source [source-wildcard]
Step 3
Example:
Switch(config)# access-list 10
•
For access-list-number, enter the access list number specified in Step 2.
•
The deny keyword denies access if the conditions are matched.
permit 10.8.1.0 255.255.224.0
•
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).
