Here is the situation. We have two sites connected with fiber, in fact all connections discussed are 1Gig fiber. Each site has two 6500's , A and B at one site and C and D at the other. A is connect to B and C ; D is connected to B and C (no A to D or B to C connections). If the A to C or the B to D connection goes down, the route(s) will change as expected. A to C then goes through B etc but this does cause some delay, I would guess for reconvergence. We attempted to shorted this time by using the variance command (variance 2) and the traffic-share command (traffic-share min). According to articles this would add the alternate routes to the routing table but not use them unless the primary route was lost. However we do not see the secondary routes in the routing table. The primary route has a metic of 3072 and the secondary has a metric of 3328, so we though a variance of 2 should be sufficient. Am I wrong about what should happen or is there something else I need to do?
Also we donot want to use unequal cost load shareing that is why we used the min parameter on the traffic-share command. Thanks
