We connected our first redundant backhaul and while OSPF is advertising the secondary route to the rest of the network, it doesn't seem to pass any traffic with the cost set equal on all routes.
The question I have first is will OSPF equal load balance to a network where that network is connected directly on one port and via another route on a second port? Example:
Router B:
10.0.0.0/16 directly connected on eth0
10.0.0.0/16 connected on eth1 via 10.2.6.1
That is the physical layout but on Router B, `show ip route` only shows 10.0.0.0/16 on the directly connected port. It shows 10.2.6.0/24 on the eth1, but now 10.0.0.0/16 via 10.2.6.1
In case someone wants to see it, here are the relavent routes shown from the 3 routers involved.
NOC router: 10.0.0.1/16
Router A: 10.0.0.6/16
Router B: 10.0.0.7/16
