MPLS AToM – Pseodowires
MPLS AToM is very different to L2TP in that it does not utlize an IP header in anyway to carry data accross an MPLS network.
AToM uses LDP extended discovery ie targeted hellos to establish an LDP session with a non-directly connected neighbor.
Lets examine the topology below.
To setup a AToM circuit using the configuration below.
