Verification:
CE1#ping 50.50.50.2
Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 50.50.50.2, timeout is 2 seconds:

!!!! !

Success rate is 100 percent (5/5), round-trip min/avg/max = 64/118/236 ms

CE2#ping 50.50.50.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 50.50.50.1, timeout is 2 seconds:

!!!! !
Success rate is 100 percent (5/5), round-trip min/avg/max = 104/172/248 ms

AToM LDP message debugging is on

00:01:14: AToM LDP [2.2.2.2]: Sending label mapping msg

vc type 5, cbit 1, vc id 1000, group id 0, vc label 16, status 0, mtu 1500

00:01:14: AToM LDP [2.2.2.2]: Received label mapping msg, id 8, graceful restart

instance 1

vc type 5, cbit 1, vc id 1000, group id 0, vc label 16, status 0, mtu 1500

NOTE: As seen above VC labels are exchanged between PE routers after the targeted-LDP session is established. It also shows each peer sends a Label Mapping message which contains FEC TLV, Label TLV and optional interface parameters. VC Type 5 indicates Ethernet Port mode.
