IP ACL --- MPLS/VPLS

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

Sherif Ismail

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.

Thanks Edison/Jeff

@ Edison

what about mpls traffic that passes after LDP adjancies are up

So this means my statment is right , correct ?

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

MPLS transport itself won't be affected.
