we have a 3560 located in head office with a 100mb fibre connection to a remote office where a 3560 is also located. we also have a 3rd site with the same. all 2 remote sites connect back to the 3560 via 100mb connection. both sites terminate via 802.1q trunk port on lets say port 0/1.
both are in a seperate vlan, vlan 1 for head office, vlan 2 for remote office 1 and vlan 3 for remote office 2. the head office switch does the inter vlan routing for both remote sites. the customer wants to use a wireless backup link for redundancy between remote office 1 and head office and remote office 2 to head office. however, the wireless is not point to point. it is point to multi-point with some extra offices off the same head end. If we setup eigrp over the head office switch and the 2 remote offices then in theory if the 100mb connection is unavilable this should re-route over the wireless in this case. Am i thinking on the correct lines on this????
