2 name: ACL Based Forwarding
3 maintainer: Neale Ranns <nranns@cisco.com>
5 - 'Policy Based Routing'
6 - ACLs match traffic to be forwarded
7 - Each rule in the ACL has an associated 'path' which determines how the
8 traffic will be forwarded. This path is described as a FIB path, so anything
9 possible with basic L3 forwarding is possible with ABF (with the exception
10 of output MPLS labels)
11 - ACLs are grouped into a policy
12 - ACL priorities within the policy determine which traffic is preferentially
14 - Policies are attached to interfaces.
15 - ABF runs as an input feature in the L3 path
