Fix Recommendation

Configure the router to only allow incoming communications from authorized sources to be routed to authorized destinations.

Implement access control lists or policy-based routing as defined in the Arista Configuration Manual, chapters 18 and 22 respectively.

Check Contents

Review the router configuration to determine if the router only allows incoming communications from authorized sources to be routed to authorized destinations.

To verify an ACL is configured to allow only incoming communications from authorized sources, execute a "show ip access-list" command and verify the pertinent permit and deny statements are in place. Validate the access list is configured on the appropriate interface via the "show ip access-list summary" command or by reviewing the interface configuration viewable in the "show running-config" command.

If PBR is being used, verify the appropriate policy maps have been configured by reviewing the switch running-config via the "show running-config" command.

If the router does not restrict incoming communications to allow only authorized sources and destinations, this is a finding.
