[j-nsp] ATM L2VPN connection help

[zeng watchthinker]

Raymond,

 According to Juniper's 
document(http://www.juniper.net/techpubs/software/junos/junos64/swconfig64-vpns/html/vpnl2-config7.html#1024109

 'You need to configure the CCC encapsulation on both the physical and 
logical interfaces.' While actually I use ATM default configuration on 
physical interafaces, L2VPN still works. I want to make sure if the 
document is true or false(Because I need to make L2/L3VPN connection with 
one port).

you'll need atm-aal5 in protocol l2vpn.
