Fault analysis
By default, an ATM subinterface uses the Point-to-Multipoint Protocol (P2MP) as the link layer
protocol. However, PWE3 does not support P2MP.
You must specify Point-to-Point (P2P) when you create an ATM subinterface.
After specifying P2P, you need to reconfigure the PW. The configuration is as follows:
[Nortel] interface atm 2/1/0.100 p2p
[Nortel-Atm2/1/0.100] mpls l2vc 3.3.3.8 33
Check the output and you can find that VC Type becomes atm aal5 sdu:
[Nortel-Atm2/1/0.100] display mpls l2vc interface atm 2/1/0.100
