name: ACL Based Forwarding
maintainer: Neale Ranns <neale@graphiant.com>
features:
- 'Policy Based Routing'
- ACLs identify how traffic should be forwarded. Packets matching a permit
rule are forwarded using ABF policy. Packets matching a deny rule are
excluded from ABF handling and continue traversing the input feature arc on
the L3 path.
- Each rule in the ACL has an associated 'path' which determines how the
traffic will be forwarded. This path is described as a FIB path, so anything
possible with basic L3 forwarding is possible with ABF (with the exception
of output MPLS labels)
- ACLs are grouped into a policy
- ACL priorities within the policy determine which traffic is preferentially
matched
- Policies are attached to interfaces.
- ABF runs as an input feature in the L3 path
