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.
