Hello,
is it possible to have a l2 gre tunnel between two controllers (AOS 6.3.0.0) with different tunnel vlans on each side (within the meaning of a access vlan).
I found this thread and it sounds that it should work but I'm unable to get that up and running.
We have two locations A (HQ) and B (remote) and in each location a controller is installed (ctrl-a, ctrl-b). There is a l2 gre tunnel and vlan 1000 at ctrl-b should be 'mapped' to vlan 10 at ctrl-a.
Configuration of ctrl-a:
interface tunnel 100
description "Tunnel Interface"
tunnel source 10.0.0.10
tunnel mode gre 0
tunnel destination 11.1.1.11
trusted
tunnel vlan 10
show interface tunnel 100 of ctrl-a
Tunnel 100 is up line protocol is up
Description: Tunnel Interface
Source 10.0.0.10
Destination 11.1.1.11
Tunnel mtu is set to 1100
Tunnel is a Layer2 GRE TUNNEL
Tunnel is Trusted
Inter Tunnel Flooding is enabled
Tunnel keepalive is disabled
tunnel vlan 10
Configuration of ctrl-b:
interface tunnel 100
description "Tunnel Interface"
tunnel source 11.1.1.11
tunnel mode gre 0
tunnel destination 10.0.0.10
trusted
tunnel vlan 1000
show interface tunnel 100 of ctrl-b
Tunnel 100 is up line protocol is up
Description: Tunnel Interface
Source 11.1.1.11
Destination 10.0.0.10
Tunnel mtu is set to 1100
Tunnel is a Layer2 GRE TUNNEL
Tunnel is Trusted
Inter Tunnel Flooding is enabled
Tunnel keepalive is disabled
tunnel vlan 1000
Everthing is fine when using the same vlan everywhere:
client: vlan 1000 ---- ctrl-b: tunnel vlan 1000 ---- cltr-a: tunnel vlan 1000 and g1/0 trunk including vlan 1000 ---- switch: trunk including vlan 1000
Everthing is fine when vlan 'mapping' will be done between ctrl-a and the switch:
client: vlan 1000 ---- ctrl-b: tunnel vlan 1000 ---- cltr-a: tunnel vlan 1000 and g1/0 access vlan 1000 ---- switch: access vlan 10
Client can't work if different tunnel vlans are used:
client: vlan 1000 ---- ctrl-b: tunnel vlan 1000 ---- cltr-a: tunnel vlan 10 and g1/0 trunk including vlan 10 ---- switch: trunk including vlan 10
Is there a trick or any other suggestions?
Thanks. Frank
