Our company are running OSPF over Cisco routers with 4 areas - 0, 2, 3 and 4.
0 is the core area linking the others together.
For end sites we don't put OSPF on as there's only 1 possible route out so we just add a default route and redistribute the site's network range from statics added to the core site's router.
We have recently added a new site to area 4 and have therefore added a new static route which is being redistributed into OSPF on the core router that the new site links back into. This is working fine and all areas picked up the new network as expected, execept for one particular 3640 core router in area 0. I've checked this router and all the OSPF is configured correctly as far as I can see(timers, key etc.) and all the neighbors are present. This router sees all the OSPF area routes and redistributed routes fine including all other static routes redistributed from the same core router that the new site links back to. However, it just won't add this one network into it's database! Does anyone know what steps I can take to troubleshoot why this one router is having this problem or has anyone experienced something similar before?
Many thanks, Paul
