Hello everyone,

I have setup L2TPv3 on AR router for one VLAN which is working, but how can we add multiple VLANs to connect using L2TPv3?


When I try to add the tunnel interface to antother VLAN it says:

interface Vlanif203
 ip address x.x.x.x
 link-bridge Tunnel0/0/0 tagged
#
interface Vlanif207
Error: Interface or tunnel have been bind.

We can only use one VLAN for L2TPv3?

here is config, it is the same on both AR routers.

interface Tunnel0/0/0
 tunnel-protocol svpn
 encapsulation l2tpv3
 l2tpv3 local session-id 1
 l2tpv3 remote session-id 2
 tunnel-source 172.16.10.1
 tunnel-destination 172.16.10.2


Please help me! Thank you!

L2TPv3 support only point-to-point connections, so you must use a different tunnel, with different source IP and destination IP. When there are multiple tunnels to be configured, the IP setting for source and destination should not overlap.

Hello,

Did you tried to apply tunnel0/0/0 to vlanif 207?
if not, please try to configure a separate tunnel interface, like tunnel 0/0/1 and then apply it to different vlan interface.

When I try to create another tunnel using the same destination address, it says another tunnel cannot be created.
