ERL and Layer Two processing
-
Look at the issue we have seen with using the ERL as a VPN end point, is it possible that the router can only handle a short number of VPN connects?
What would be the maximum number of L2TP connections that the ERL can handle before throwing connection failures.

Short number?
-
You would probably see issues with memory and CPU if the ERL is reaching its maximum. Do you have the ability to monitor that?

Yes, this should be a capacity issue, not a connection number limit.

VPN connections use almost no resources, not on their own. But one busy VPN handling a lot of traffic can use all resources on its own. VPN connection count is a licensing concern on some devices, but not a technological concern.

Do VPN connections get created/torn down with every communication? Or are they persistent until the device disconnects?

Normally neither. They are normally persistent until a certain amount of time, then they tear down when idle. Might be hours or days. That way they don't remain absolutely forever, but normally a very long time.
