5 - 'Policy Based Routing'
6 - ACLs identify how traffic should be forwarded. Packets matching a permit
7 rule are forwarded using ABF policy. Packets matching a deny rule are
8 excluded from ABF handling and continue traversing the input feature arc on
10 - Each rule in the ACL has an associated 'path' which determines how the
11 traffic will be forwarded. This path is described as a FIB path, so anything
12 possible with basic L3 forwarding is possible with ABF (with the exception
13 of output MPLS labels)
14 - ACLs are grouped into a policy
15 - ACL priorities within the policy determine which traffic is preferentially
17 - Policies are attached to interfaces.
18 - ABF runs as an input feature in the L3 path
