Hello,
I’m looking for information on setting up a Cisco L2TP Tunnel Switch to load balance incoming L2TP tunnels (from our DSL wholesaler) across 1 or more Mikrotik boxes.
Some background info:
Currently, we use a single Cisco 2621XM to terminate the l2tp tunnels, and provide pppoe service. We would like to offload all of the pppoe onto Mikrotik boxes to perform bandwidth shaping and load balancing.
In the past, we have experimented with using a Mikrotik box to terminate the l2tp tunnel directly from our wholesaler, but they appear to be using older l2tp auth mechanisms (on our Cisco router, we specify only the terminate-from and tunnel secrets in our vpdn-group–no ipsec either–I can’t seem to setup the Mikrotik l2tp server with an equivalent configuration). Consequently, we have yet to get their l2tp tunnels to authenticate directly on the Mikrotik box.
On that note:
Instead of terminating the l2tp tunnels directly on our Mikrotik system, we would like to try using our 2621 to terminate the tunnels from the wholesaler and then use vpdn-multihop to Tunnel Switch the l2tp connections onto one or more Mikrotik boxes, on which we will provide pppoe service.
First of all, am I out to lunch or is this setup technically possible?
How well does cisco l2tp play with Mikrotik l2tp?
The first task I would like to accomplish in testing this setup is to get the Cisco 2621 to establish a plain l2tp connection to a Mikrotik l2tp server (no ipsec, simple authentication). Any help I can get for both the Mikrotik and the Cisco end of things would be much appreciated!
