Filters

Routing policies can use the following filters to match routes.

ACLs include IPv4 ACLs and IPv6 ACLs. An ACL can match the destination or next hop of routes.

For more information about ACLs, see ACL and QoS Configuration Guide.

IP prefix lists include IPv4 prefix lists and IPv6 prefix lists.

An IP prefix list matches the destination address of routes. You can use the gateway option to receive routes only from specific routers. For more information about the gateway option, see "Configuring RIP".

An IP prefix list, identified by name, can contain multiple items. Each item, identified by an index number, specifies a prefix range to match. An item with a smaller index number is matched first. A route that matches one item matches the IP prefix list.
