[rbak-nsp] lns card selection

[Jim Tyrrell]

Hi,

I have configured an l2tp peer with the lns card selection command but 
the session will only establish if traffic is routing in/out of the card 
that the session terminates on:

  l2tp-peer unnamed
   session-auth chap
   tunnel-auth key tunnelpass1
   function lns-only
   max-tunnels 50
   lns card selection priority
   lns card 4 preference 10

With this setup the session only establishes if I shutdown port 1/1 so 
that the default route is via 4/1.  And if I specify "lns card 1 pref 
10" instead then the session only establishes if the default route is 
via card 1.  Am I missing something obvious?  I thought this config 
should allow sessions to be terminated on any traffic card regardless of 
which one the traffic actually routes out of?

When it fails it seems to get stuck during the PPP negotiation:

When the default route is via the same 'lns card' then this works fine.  
This is running 6.2.1.2.

Thanks.

Jim.
