Configuring PIM

Manually Assigning an RP to Multicast Groups (CLI)

If the rendezvous point (RP) for a group is learned through a dynamic mechanism (such as Auto-RP or BSR),
you need not perform this task for that RP.
Senders of multicast traffic announce their existence through register messages received from the source
first-hop router (designated router) and forwarded to the RP. Receivers of multicast packets use RPs to join
a multicast group by using explicit join messages.
RPs are not members of the multicast group; they serve as a meeting place for multicast sources and group
Note
members.
You can configure a single RP for multiple groups defined by an access list. If there is no RP configured for
a group, the multilayer device responds to the group as dense and uses the dense-mode PIM techniques.
This procedure is optional.
SUMMARY STEPS
1. enable
2. configure terminal
3. ip pim rp-address ip-address [access-list-number] [override]
4. access-list access-list-number {deny | permit} source [source-wildcard]
5. end
6. show running-config
7. copy running-config startup-config
DETAILED STEPS
Command or Action
Step 1
enable
Example:
Device> enable
Step 2 configure terminal
Example:
Device# configure terminal
Step 3 ip pim rp-address ip-address
[access-list-number] [override]
Example:
Device(config)# ip pim rp-address
OL-29890-01
Purpose
Enables privileged EXEC mode.
• Enter your password if prompted.
Enters the global configuration mode.
Configures the address of a PIM RP.
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).
If there is no RP configured for a group, the device treats the group
Note
as dense, using the dense-mode PIM techniques.
