Route Filtering and IP Policies

When the switch routes IP traffic, you can apply a number of filters to manage, accept, redistribute, and announce policies for unicast routing table information. Filters apply differently to different unicast routing protocols.

Note

Note

IPv6 ingress QoS ACL/Filters and IPv6 Egress Security and QoS ACL/Filters are not supported. For information on the maximum number of IPv6 ingress port/vlan security ACL/filters supported on the switch, see Fabric Engine Release Notes.

The following figure shows how filters apply to BGP, RIP, and OSPF protocols.
