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.

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?
