Fix Recommendation

This requirement is not applicable for the DODIN Backbone.

Configure neighbor filters to only accept PIM control plane traffic from documented PIM neighbors. Bind neighbor filters to all PIM enabled interfaces.

Step 1: Configure an ACL that only permits documented neighbors.

OS10(config)# ip access-list PIM_NBR_FILTER
OS10(config-ipv4-acl)# permit ip 10.10.10.2/32 any

Step 2: Apply the ACL to the PIM interfaces.

OS10(config)# interface vlan 100
OS10(conf-if-vl-100)# ip pim neighbor-filter PIM_NBR_FILTER

Check Contents

This requirement is not applicable for the DODIN Backbone.

Review the multicast topology diagram and determine if router interfaces are enabled for IPv4 or IPv6 multicast routing.

If the router is enabled for multicast routing, verify all interfaces enabled for PIM have a neighbor filter bound to the interface. The neighbor filter must only accept PIM control plane traffic from the documented PIM neighbors.

Step 1: Verify that a PIM neighbor filter has been configured.

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

Step 2: Verify all interfaces enabled for PIM have the neighbor filter bound to the interface.

!
interface vlan100
no shutdown
ip pim sparse-mode
ip pim neighbor-filter PIM_NBR_FILTER

If PIM neighbor filters are not bound to all interfaces that have PIM enabled, this is a finding.
