We have been testing OSPF on our network now that our wireless WAN links are a stable. Basically what we are trying to do is get the routers to re-route traffic between our sites via Diginet in the event that our wireless link goes down.
We tested it on our Cisco routers and everything seemed fine, but the Windows clients are not playing the game. Basically we have 2 routers on each subnet, one for Wireless (Mikrotik) and the other for Diginet (Cisco).
When we disconnect the LAN cable for the Mikrotic router the Cisco automatically detects this and then re-routes traffic via the Diginet. The windows clients however do not go through the Diginet.
On closer inspection we noted that in the Windows routing table (route print) on the client machines they have a route to the remote subnet via the Wireless router. The strange thing is that their default gateway set via DHCP is the Cisco router yet they still have this entry in the routing table.
If anyone out there has had something similar could they please help out. We have been scratching our heads for a couple of days now and can not find anything usefull on Google yet. (Clearly our search strings are all messed up!)
The one solution that we have thought of is to put the mikrotik router on its own subnet and set the Cisco's LAN interface to have addresses on both subnets. This would mean that the Wireless equipment will not be directly accessible from the local client subnet and only allow traffic to traverse this link via the Cisco ethernet interface. The only problem with this scenario is that it will result in a lot of network downtime to setup and that there is the possibility that the client connection to the wireless may be limited to the speed of the 10Mbps ethernet port on the Cisco router.
