PurposeCommand or Action
Example:
Device> enable
Enters the global configuration mode.configure terminal
Example:
Device# configure terminal
Step 2
Configures the address of a PIM RP.
ip pim rp-address ip-address
[access-list-number] [override]
Step 3
By default, no PIM RP address is configured. You must configure the IP
address of RPs on all routers and multilayer devices (including the RP).
Example:
Device(config)# ip pim rp-address
If there is no RP configured for a group, the device treats the group
as dense, using the dense-mode PIM techniques.
Note
10.1.1.1 20 override
A PIM device can be an RP for more than one group. Only one RP address
can be used at a time within a PIM domain. The access list conditions specify
for which groups the device is an RP.
•
For ip-address, enter the unicast address of the RP in dotted-decimal
notation.
•
(Optional) For access-list-number, enter an IP standard access list number
from 1 to 99. If no access list is configured, the RP is used for all groups.
•
(Optional) The override keyword indicates that if there is a conflict
between the RP configured with this command and one learned by
Auto-RP or BSR, the RP configured with this command prevails.
Creates a standard access list, repeating the command as many times as
necessary.
access-list access-list-number {deny |
permit} source [source-wildcard]
Step 4
Example:
Device(config)# access-list 25
•
For access-list-number, enter the access list number specified in Step 2.
•
The deny keyword denies access if the conditions are matched.
permit 10.5.0.1 255.224.0.0
•
The permit keyword permits access if the conditions are matched.
•
For source, enter the multicast group address 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.
The access list is always terminated by an implicit deny statement for
everything.
