The best way to transition from our switched network to routed that I can figure is to set up the existing VLANs for our geographic areas as OSPF areas and start dividing off our existing tower sites with mikrotiks on-site. I've had a backbone area set up between our Riverstone (ASBR) and mikrotik routers (ABRs), and now I've created the additional areas for the three vlans.
The riverstone has the default route out of the network and is DR for backbone area 0 and is only a member of area 0, so it should be the ASBR. By my reckoning, the backbone mikrotiks should be ABRs (members of area 0 and 1, 2, 3), then the tower site mikrotiks will be members of 1, 2, OR 3. But, they're all showing as ASBRs, and I'm not understanding why. They're all only running OSPF, and there is only one router (only in area 0) with a static default route out of the network. Any thoughts why I'm seeing this? Here is a simple example of my OSPF configuration. In reality the IPs are different and there will be more routers in each zone, but first things first...: Area 0 (broadcast), 10.0.0.0/27, riverstone-1 ASBR is 10.0.0.1 and mikrotik-1 ABR is 10.0.0.2 Area 1 (NBMA), 10.0.0.32/27, mikrotik-1 ABR is 10.0.0.33 and mikrotik-2 @ tower A is 10.0.0.34 Area 2 (NBMA), 10.0.0.64/27, mikrotik-1 ABR is 10.0.0.65 and mikrotik-3 @ tower B is 10.0.0.66 Area 3 (NBMA), 10.0.0.96/27, mikrotik-1 ABR is 10.0.0.97 and mikrotik-4 @ tower C is 10.0.0.98 Thanks! -Paul -------------------------------------------------------------------------------- WISPA Wants You!
