Hi, I am trying to configure a QinQ link between two building. Building1 -- ServiceProvider -- Building2
ServiceProvider won't do QinQ in their equipment. In Building1 and Building2 there is only one 3560 switch. I did some test and it's working with a loop between gig0/23 and gig0/24 but i am not sure if it's the correct way. Will having a config like this be alright ? I see packet loss from time to time ... interface GigabitEthernet0/22 description SP-UPLINK switchport trunk encapsulation dot1q switchport trunk allowed vlan 201 switchport mode trunk ! interface GigabitEthernet0/23 description QinQ (looped to gi0/24) switchport trunk encapsulation dot1q switchport trunk allowed vlan 1-200,202-4094 switchport mode trunk ! interface GigabitEthernet0/24 description QinQ (looped to gi0/23) switchport access vlan 201 switchport mode dot1q-tunnel mls qos trust cos l2protocol-tunnel cdp l2protocol-tunnel stp l2protocol-tunnel vtp no cdp enable _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
