OSPF load balancing across WiMAX links

[jennyjohn]

We have a Ship connected to onshore via 2 WiMAX links (as shown in diagram). We already have OSPF running at the onshore office, which we would like to extend to the ship.

The ship will be connected by either link 1 or link 2 based on its location. In some cases the ship might be connected to onshore by both the links, in which case OSPF load balancing should work. If both the links are up, but if one link is very weak with very low bandwidth, is it possible for OSPF to prefer the strong link.

Thanks in advance.

OPSF does not understand "weak signal" or "low badnwidth" of a radio signal.

It understand physical interface badnwdiths and load balances accodringly.

OSPF is all or nothing.  OER/PfR can monitor end-to-end quality and change routing on what it "sees".  If your platform supports it, that would probably be the easiest and possible best solution.

Otherwise, you might be able to build some type of IP SLA test that a script you write repeatedly monitors, and change routing metrics as necessary (but that's what OER/PfR actually does).

I have the  same problem with my OSPF network, when the redundant  link is very weak it stays connected but causes glitches in the network. What I would like to do, if there is a way, is to tell the link to completely shut down when it is below a specific bandwidth based on SNMP report so that the OSPF will re-route better.

Thanks
