OS10# configure terminal
OS10(config)#
OS10(config)#
OS10(config)# ip access-list PIM_REGFILTER
OS10(config-ipv4-acl)# permit ip 10.10.10.2/32 any
OS10(config-ipv4-acl)# exit
OS10(config)#
OS10(config)# ip pim register-filter PIM_REGFILTER

Check Contents

Verify the RP router is configured to filter PIM register messages.

!
ip access-list PIM_REGFILTER
seq 10 permit ip 10.10.10.2/32 any
