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
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.
The following figure shows how filters apply to the IS-IS protocol for Fabric Connect Layer 3 VSNs or IP Shortcuts.
