rp-address access list (IPv4)

rp-address[access-list][override]

no rp-address[access-list][override]

Description

Statically configures the router as the RP and associates the static RP to the specified ACL.

Thenoform of this command removes static RP ACL configuration.

Parameter

Description

Specifies the address of the static RP in IPv4 format (x.x.x.x), wherexis a decimal number from 0 to 255.

access-list

Specifies the name of the access control list.

override

Specifies whether or not static RP configuration precedes the information learned by a BSR.

Usage

The ACL includes a list of permitted/ denied group addresses for the specified RP.

  • When configured on a source DR, only permitted group addresses are registered to the RP. When applied on other routers, (\*,G) PIM join/prune messages are filtered according to the applied ACL.
  • Only destination group addresses in the ACEs are filtered and any other fields configured in the ACE are ignored. If only PIM (\*,G) messages need to be filtered, configureaccept-rpACLs.
  • When static RP ACL is configured, only one static RP can be configured per VRF and that configured RP handles all the multicast groups in range 224.0.0.0/4.

A change in the RP ACL does not impact the flows that have already switched to SPT. Only when the source information is expired and the RP is needed to establish the multicast tree, is the change in the ACL reflected. If the source is always active, PIM can be disabled and re-enabled to clear the learned sources information and re-establish multicast trees based on the latest RP ACL configurations.

Examples

Configuring the static RP ACL:

... access-list ip static_rp_acl 10 permit any any 225.1.1.1 20 permit any any 239.1.1.0/255.255.255.0 30 deny any any 226.1.1.0/255.255.255.0 switch(config)#router pimswitch(config-pim)#rp-address 40.0.0.4 access-list static_rp_acl

Removing the static RP ACL configuration:

switch(config-pim)#no rp-address 40.0.0.4 access-list static_rp_acl
