[c-nsp] ATM over IP

[Vincent De Keyzer]

Hi Tim,

we have been happily doing this for over a year now.

Our config looks like this:

l2tp-class L2L-L2TP
 authentication
 password somepassword
!
pseudowire-class L2L-PW
 encapsulation l2tpv3
 protocol l2tpv3 L2L-L2TP
 ip local interface Loopback5287

interface Loopback5287
 ip address 10.52.87.6 255.255.255.255
 no clns route-cache

interface ATM2/0.211 point-to-point
 description Customer321
 no atm enable-ilmi-trap
 pvc Customer321 0/211 l2transport
  vbr-nrt 8000 8000
  encapsulation aal5snap
  xconnect 10.52.87.2 211 pw-class L2L-PW
 
You might want to use a different encapsulation. We selected aal5snap
because in our understanding, each IP packet encapsulated into ATM will be
put in one packet over the L2TP network.
