Hi Irwan

May be it worth to clarify the following reg LDP :

CE1---PE1-----P1-----P2-----PE2----CE1

Guess the above is U setup .

As Normal : PE1 & P1 are LDP peer , P1 & P2 are LDP peer , and P2 & PE2 are 
LDP Peer.
Also when  U configure EoMpls , PE1 & PE2 will be LDP (targeted) peer to 
exchange the Psuedowire Label's .

Attn: The List

As Far as I recall , in CSCO box the targeted LDP is initiated implicitly 
when U config AToMPLS (when specifying the remote end ) . But ,Did PE1 and 
PE2 will exchange just the Pusedowire Label or also
will exchamge label for IPv4 in CSCO implementation (which is not needed ) .

Brgds
