Hello,
we have a connection from a service provider between location A and B where in location A i have an ethernet port and i configure a switch interface as trunk with 802.1q encapsulation and i try to pass vlans 421-423. in location B the ethernet is presented in the form of a Q-in-Q trunk. So from what i understand the vlans i put in the trunk in location A are encapsulated inside what the service provider called svlan with the id 10. i have the following configuration of the ethernet port in location B:
interface GigabitEthernet2/0/25
description Eircom_Fibre
switchport access vlan 10
switchport trunk encapsulation dot1q
switchport mode dot1q-tunnel
l2protocol-tunnel cdp
l2protocol-tunnel stp
l2protocol-tunnel vtp
no cdp enable
now i was hoping i could simply configure another interface as .1q trunk and pass traffic on via a normal trunk instead of Q-in-Q. the interface for that is configured as follows:
interface GigabitEthernet2/0/1
description Ceragon Payload
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 421,422
switchport mode trunk
unfortunately i can not pass traffic. it seems the switch is not picking the vlans out of the svlan with the id 10. can anybody advise how i can access the vlans from within the q-in-q trunk ?
Kind Regards
Jan
