Licensing Requirements for Access Rules
Access Rules for Returning Traffic
Because EtherTypes are connectionless, you need to apply the rule to both interfaces if you want traffic
to pass in both directions.
Allowing MPLS
If you allow MPLS, ensure that Label Distribution Protocol and Tag Distribution Protocol TCP
connections are established through the ASA by configuring both MPLS routers connected to the ASA
to use the IP address on the ASA interface as the router-id for LDP or TDP sessions. (LDP and TDP
allow MPLS routers to negotiate the labels (addresses) used to forward packets.)
On Cisco IOS routers, enter the appropriate command for your protocol, LDP or TDP. The interface is
the interface connected to the ASA.
ciscoasa(config)# mpls ldp router-id interface force
Or
ciscoasa(config)# tag-switching tdp router-id interface force
