Using Xconnect l2tp with 3 locations

[Kasun Bandara]

Hi there,

i am trying to do below scenario. i tried to configure it with my solution. but its not worked. any idea from experts?

requirement :

                        L2 Network                            L3 Network                              L2 Network

                                                          ------------------------------------------- router 2 ------------ Client Device 0

                                                         /

Central Device ------------------ router 1 --------------------------------------- router 3 ------------ Client Device 1

Central device and client devices need to be in same Layer 2 network with same IP range. i configured client device 0 network using  xconnect between router 1 and router 2. due to only one xconnect command can have per interface i cannot configure network for router 3. so i came up with below network as a experiment.

                        L2 Network                            L3 Network                              L2 Network

                                                          ------------------------------------------- router 2 ------------ Client Device 0

                                                         /

Central Device ----Switch==== router 1 --------------------------------------- router 3 ------------ Client Device 1

I connected switch to router using 2 links and those two interfaces in router configured with 2 xconnect commands. 1 tunnel came up and second tunnel not shows any packet moving through it.

please let me know if you have any idea. 

thanks in advance for looking in to this

Hi Kasun,

L2TP VPN is a point to point method, you could have multipoint using VPLS or HVPLS. Unfortunately L2TP will not work to interconnect 3 or more locations.

Hi Julio,

thanks a lot for reply. is there any documents for VPLS, HVPLs?

thank you
