From our HQ we have to links to our datacentre located remotley. One is a direct 100mb link and the other is a 1000mb link connection to a another site which then has a 1000mb link to the datacentre.
OSPF is routing traffic over the two 1000mb connections as this is the 'best' route even though the 100mb link is a direct connection.
This means the 100mb link is idle until we have a link failure elsewhere.
Can OSPF be reconfigured so that all links are used? i.e some traffic via the 1000mb links and some via the 100mb link? In affect, unequal cost routing?
Is this an OSPF feature or would we need to use EIGRP as our routing protocol?
One other consideration is we run a fully routed network with only a small amount of layer 2 traffic at the datacentre local site.
