[rbak-nsp] L2tp timeout

[Kenny Lunsford]

The Stale sessions would be ones that the user sent a disconnect or the PC disconnected b/c of timeout, but the session is not cleared inside the Peer tunnel, so when they reconnect they will have multiple sessions up.

On the ppp keep-alive command would that work across all connection types, l2tp, ppp, that are inside the same user context?

What do you mean by 'stale tunnel sessions'?

You can use "ppp keepalive check-interval seconds 30 retries 3" in the user context to send keepalives to the customer CPE and clear the connection if its not responding.

You can use " l2tp clear-radius-peer 5" to clear Tunnels established via Radius after 5 minutes if there are no sessions.

We have a Redback 800 running 6.2.1.7  We currently have multiple L2tp tunnels set up inside a context to authenticate and serve customers.  My question is what setting do I need to clear stale tunnel sessions inside each peer group.  A group peer looks like the following:

l2tp-peer name woodwardugc.wow.pldi.net media udp-ip remote dns woodwardugc.wow.pldi.net local 192.168.37.28
  session-auth pap chap
  function lns-only
  local-name wow.pldi.net

There is a timeout command but I didn't know if that was what it was for under the l2tp-peer commands.
