Hello,
I'm looking to familiarise myself with GRE tunnels ahead of some work I'm doing for a customer next month. What I'm looking to tunnel a L2 VLAN carrying guest traffic from one site to another across the WAN as a temporary measure.
In order to test this in the lab I've created an arbitrary VLAN (207) on two controllers in my lab, and am attempting to pass traffic between them. I have the following configuration:
Controller 1:
interface tunnel 2071
description "Tunnel Interface"
tunnel mode gre 1
tunnel source 192.168.38.10
tunnel destination 192.168.38.11
tunnel keepalive
trusted
tunnel vlan 207
!
Controller 2:
interface tunnel 2071
description "Tunnel Interface"
tunnel mode gre 1
tunnel source 192.168.38.11
tunnel destination 192.168.38.10
tunnel keepalive
trusted
tunnel vlan 207
!
As these are both arbitrary VLANs I've done operstate up on both to bring them online, and the tunnel is showing as up. However I can't see anything matching it in the datapath tunnel table, and I can't ping the VLAN 207 interface on the other controller through the tunnel.
Have I missed something here?
