Core consist of 6509 where all the access vlans has been configured.
Access vlan ips - 10.0.0.0 range.
server vlan 172.21.0.0 as mentioned in dia.
Backbone router consist of 7200 series router where all the branch office at terminated through FR link.
EIGRP config has been mentioned in brief network diagram.
We hv got TLS service from verizon for three of our location i.e for core(100Mbps) and two of branch office(10Mbps). Am not very sure about the TLS and also confirmed that it work as regular 802.1q trunk.
I wanted to know as how can I configure the Branch office Vlan on Core and make the TLS as the primary link for two of our branch office without any major EIGRP routing changes. The Brachoffice 1 & 2 will still remain on Frame-relay Also would like to use existing Frame-relay ckt at the branch as a backup to TLS for Branch office 3 &4 ?
