There's a difference between not recommending something, and something not being possible. By reading the manual I understood that the Max COULD be an ABR, you even went so far as to draw a diagram showing exactly what the topology would look like, WITH MAXES! I'm just trying to verify how this would work on a Max. My understanding now from you is that the Max CANNOT be a ABR. Is this accurate? That said, does Ascend have a discussion somewhere of how they recommend the implementation of OSPF on the Maxes, from a topology standpoint? I know there are lots of people running OSPF on their Maxes, I'm beginning to migrate our network from RIP/Static Routes to OSPF. My topology had the Ascends as Area Border Routers. What are other people doing? Here's the topology I built: RTR#1 RTR #2 | | | | | | | | 20 Net Switch Card (10 Mb) |-------*--*--*--*--*--*--*--*--*---*--)---*--)--| | | | | | | | | | | | Max 400X Modem Pool (9 hosts) | | | | | | 21 Net Switch Card (10 Mb) |-------*-*-*-*-*-*-*-*-----*-*-*-*----*------*--| | | | | | | | | | | | | | | | | | | | | Max TNT Max 400X Modem Pool (8 hosts) I was planning on making the 20 and 21 Net Switch Cards Area 0. Then I was going to pair up Ascend Maxes, assign each a /25 subnet, and put their WAN interfaces in the same Area. However, that would require the Ethernet port of the Max to be in a different Area than the WAN ports. My only other question would be: If they can't be ABRs, than the Maxes can only be Stub Area routers? Oh well. Thanks for all the help. -Rob On Wed, 1 Oct 1997, Matt Holdrege wrote: > At 07:43 AM 10/1/97 -0400, Robert A.
