Bryan..

Its a flat layer 2 network with all access switches... I'm upgrading this 
network to have layer 3 functions to support 2500 users who are all currently 
using vlan 1 ( not allowed on a dod infrastructure)..

I've configured a core switch (4507) which houses all the vlan.. and now I want 
to propagate the newly configured vlans to the edge devices... setup is as 
follows:

(vlans-4507-core switch with 32 vlans) ---> Master TACLANE-----> user access 
TACLANE ----> 4507 (vlan 1& users)... the entire infrastructure was built this 
way..

I've tried gre tunnels... but its a no go... 

I've tried L2PT ... its a no go...

Requirement that I would like to meet if possible is to some how get the 32 
vlans to all edge devices.

Who ever built the network did not plan for growth and the personnel on the 
ground here does not want to spend the extra money or purchase extra equipment 
for us to redesign.

Cedric,

I am kind of confused about the topology. Can you explain better what the 
requirements area? Is the interface between the 4507's and the TACLANES L3 or 
L2? Is it

vlans---> 4507 ---> TACLANE -----> TACLANE ----> 4507 ----> vlans

And the vlan networks need to communicate via layer 2?
