ACL based RP assignment
ACL based RP assignment
The
A static RP by default serves the range of 224.0.0.0/4 if the RP is configured without an ACL name. If an ACL name is given but the ACL is not defined, the static RP is set to inactive mode and it will not cover any multicast group ranges.
The optional static RP ACL can be configured as a standard ACL or as an extended ACL. For an extended ACL, the destination filter will be used to derive the multicast group range and all other filters are ignored. The content of the ACL needs to be defined in the order of prefix length; the longest prefix must be placed at the top of the ACL definition.
If there are overlapping group ranges among the static RPs, the static RP with the longest prefix match is selected. If more than one static RP covers the exact same group range, the highest IP static RP will be used.
Configuration considerations:
•The Static RP has higher precedence over RP learnt from the BSR.
•There is a limit of 64 static RPs in the systems.
Configuring an ACL based RP assignment
To configure an ACL based RP assignment, enter commands such as the following.
device(config)# router pim
Syntax: [no] rp-address ip_address [acl_name_or_id ]
Use the ip address parameter to specify the IP address of the device you want to designate as an RP device.
Use the acl name or id (optional) parameter to specify the name or ID of the ACL that specifies which multicast groups use this RP.
Displaying the static RP
Use the show ip pim
device(config)# show ip pim
Static RP count: 4 130.1.1.1 120.1.1.1 120.2.1.1 124.1.1.1
