Hi there,
I have a port on a Cat 6509 in mode trunk :
Interface Gigabit1/1
switchport
switchport mode trunk
switchport trunk allowed vlan 10,20
!
Is it possible for me to rewrte theese tags (10,20) to 11 and 21, so that I can have vlan interface for each of them on the 6509?
So instead of:
Interface vlan 10
ip address 10.10.0.1 255.255.255.0
!
Interface vlan 20
ip address 10.10.0.1 255.255.255.0
!
the vlans recieved on the trunk should be rewritten to: 10->11, 20->21
Interface vlan 11
ip address 10.10.0.1 255.255.255.0
!
Interface vlan 21
ip address 10.20.0.1 255.255.255.0
!
So 10.10.0.1/24 and 10.20.0.1/24 is reachable on Gig1/1 on vlan 10 and 20.
Is this possible and how?
Note: I have SUP720 and some GigE line cards in the Cat 6509....
Please advice! :-D

Philip,
As far as I know - there are two options:-
1) 802.1q-in-q tunneling

2) Ethernet over MPLS - VLAN ID rewrite
