I was trying to use Dynamips to verify it, but Dynamips was running too slow on my computer. Can someone please verify if what I plan to do works?
Site A ----------- Site B
Both have WAN links into the cloud, running EIGRP with all other sites and wit each other. A and B also have a direct connection as backup link, running OSPF over the link.
Site A internal networks are in Area 20
Site B internal netowrks are in Area 30
Direct link between A and B is in Area 0
The direct link is used as a failover link to the WAN connections. I'm thinking to summary from Area 20 to Area 0 at A and from Area 30 to Area 0 at B as the fllowing:
Site A#
router ospf 1
area 20 range 10.0.0.0 255.255.255.0
area 20 range 192.168.0.0 255.255.0.0
Site B#
router ospf 1
area 20 range 10.0.0.0 255.255.255.0
area 20 range 192.168.0.0 255.255.0.0
10.0.0.0/8 and 192.168.0.0/16 can cover everything in the company. Is it ok that I have the same summary routes into Area 0 from two areas? My goal is to have either site learn the OSPF summary routes as from the direct link in between.
I think it works. I just don't have the tool to test right now.
Thanks a lot
