Purpose
Command or Action
configured RPs. Assume that it is desirable to use a second RP for the local
groups.
Enters the global configuration mode.
configure terminal
Example:
Device#
configure terminal
Step 3
Configures another PIM device to be the candidate RP for local groups.
ip pim send-rp-announce interface-id
scope ttl group-list access-list-number
interval seconds
Step 4
•
For
interface-id
, enter the interface type and number that identifies the
RP address. Valid interfaces include physical ports, port channels, and
VLANs.
Example:
Device(config)#
ip pim
•
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.
send-rp-announce gigabitethernet
1/0/5 scope 20 group-list 10
interval 120
•
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.
access-list access-list-number
{
deny
|
permit
}
source
[
source-wildcard
]
Step 5
Example:
Device(config)#
access-list 10
•
For
access-list-number
, enter the access list number specified in Step 3.
•
The
deny
keyword denies access if the conditions are matched.
permit 10.10.0.0
•
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.
Note
Finds a device whose connectivity is not likely to be interrupted, and assign
it the role of RP-mapping agent.
ip pim send-rp-discovery scope ttl
Example:
Device(config)#
ip pim
Step 6
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
send-rp-discovery scope 50
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.
