I have two links(L-2) between Same cisco 4507 L-3 Switches.First link is in production(with multiple Vlans i.e 2,3,4,5),second link(allowed with same vlans as on First link) and kept admin down/shut always.We only maually activate the second link for shifting traffic when there is failure on First link.
I want to make the traffic shifting automate i.e auto-shifting of traffic to Second Link after outage of first/Primary link.
I am planning to make one Switch as root by command "spanning-tree vlan 2,3,4,5 root primary" .
Please suggest is this a good solution in sense of future prospects or there may be any other simple way for fullfilling the requirement.
Atached is the scenerio.
