Users Guide

To configure an ACL that is used for a register filter:
1. Configure an ACL in CONFIGURATION mode. You can specify the ACL name up to 140 characters.
OS10# configure terminal
OS10(config)# ip access-list pim_reg_filter
OS10(config-ipv4-acl)# permit ip 10.10.10.2/32 any
The PIM register filter uses both source and group information from the access-list for filtering register messages.
2. Configure a register filter that applies the previously created ACL (pim_reg_filter) in the default or nondefault VRF.
OS10(config)# ip pim vrf vrf_dell register-filter pim_reg_filter
In this example, the register filter is configured in a nondefault VRF named vrf_dell.
