Dears
I would like your assistance regarding below plz
when I configure "access-list permit ip any any"
Actually this will permit all IP packets
However what about L2 protocols/packets as MPLS, VPLS, ... etc
Will it match ? According to lab I made, It didnt match but packets were permitted
So this means, If I configured this access-list under any interface
It will only filter IP packets & all other protocols rather than IP (as MPLS, VPLS or even IPX) will not be filtered & will be permitted normally
Am I correct ?
Many Thanks

MPLS adjancencies will use TCP port 646 for LDP so an IP ACL will affect it.

certainly ipx is unaffected. There are separate acls for ipx.

@ Edison
what about mpls traffic that passes after LDP adjancies are up
So this means my statment is right , correct ?

MPLS transport itself won't be affected.
