Configuring PIM
Command or Action
Example:
Device(config)# ip pim
send-rp-announce gigabitethernet
1/0/5 scope 20 group-list 10
interval 120
Step 5
access-list access-list-number {deny |
permit} source [source-wildcard]
Example:
Device(config)# access-list 10
permit 224.0.0.0 15.255.255.255
Step 6 ip pim send-rp-discovery scope ttl
Example:
Device(config)# ip pim
send-rp-discovery scope 50
Step 7 end
Example:
Device(config)# end
Step 8
show running-config
Example:
Device# show running-config
OL-29890-01
Purpose
• For scope ttl, specify the time-to-live value in hops. Enter a hop count
that is high enough so that the RP-announce messages reach all mapping
agents in the network. There is no default setting. The range is 1 to 255.
• For group-list 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.
• For interval seconds, specify how often the announcement messages
must be sent. The default is 60 seconds. The range is 1 to 16383.
Creates a standard access list, repeating the command as many times as
necessary.
• For access-list-number, enter the access list number specified in Step 3.
• The deny keyword denies access if the conditions are matched.
• The permit keyword permits access if the conditions are matched.
• 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.
Finds a device whose connectivity is not likely to be interrupted, and assigns
it the role of RP-mapping agent.
For scope ttl, specify the time-to-live value in hops to limit the RP discovery
packets. All devices within the hop count from the source device receive the
Auto-RP discovery messages. These messages tell other devices which
group-to-RP mapping to use to avoid conflicts (such as overlapping
group-to-RP ranges). There is no default setting. The range is 1 to 255.
To remove the device as the RP-mapping agent, use the no ip pim
Note
send-rp-discovery global configuration command.
Returns to privileged EXEC mode.
Verifies your entries.
