Configuring Multiple Rendezvous Points in a Domain
You can configure multiple RPs in a shared-tree PIM sparse-mode domain. You need to configure an MSDP local address to enable the RPs in the domain to maintain a consistent view of the active sources.
To configure a router to act as an RP in a domain with other RPs, do the following for each router in the domain that acts as an RP:
- Create the router ID by configuring a unique and routable IP address on the loopback interface and setting the primary address flag.
- Configure a non-unique, but routable, unicast address on the loopback interface.
- Use the non-unique, routable unicast address to configure the PIM router to be the local RP.
- Configure MSDP with the unique and routable address (router ID) as the local address of the peer.
For a sample configuration of multiple RPs, see Example: Configuring a Router to Use Anycast RP. For more information about configuring interfaces, see the Junos Network Interfaces Configuration Guide.
Example: Configuring a Router to Use Anycast RP
The following example configures a router to use anycast RP:
[edit]interfaces {...lo0 {unit 0 {family inet {# This must be a unique routable address and router-idaddress 10.1.1.1/32 {primary;}# This must be a non-unique routable anycast
RP addressaddress 10.10.10.10/32;address 127.0.0.1/32;}}}}routing-options {interface-routes {rib-group ifrg;}rib-groups {ifrg {import-rib [ inet.0 inet.2 ];}mcrg {export-rib inet.2;import-rib inet.2;}}autonomous-system 1234;}protocols {bgp {group red {type internal;family inet any;neighbor 10.1.1.2 {local-address 10.1.1.1;}}}msdp {rib-group mcrg;group red {peer 10.1.1.2 {local-address 10.1.1.1;}}}pim {dense-groups {224.0.1.39/32;224.0.1.40/32;}rib-group mcrg;rp {local {address 10.10.10.10;}}interface all {mode sparse-dense;version 2;}interface fxp0.0 {disable;}}}
