Folks, I'm experimenting with using Zebra running on a Debian box to do OSPF with the Ciscos on our network. The zebra box has 2 interfaces, each in a different area. This is the first time we have tried to impliment multiple areas on our network. Right now, area 51 consists only of the zebra box and a Cisco 2500, and is just for testing. The zebra box is forming a full adjacency with the Cisco in area 51 with no problems. It will not, however, become fully adjacent with the DR and BDR in area 0. This seems to be preventing the distrobution of routes to the zebra box. Distrobution of routes in area 51 works fine. Here is my config, minus auth info. !

Have you tried it without the message-digest? I messed with this back in the day and I had problems with the keys and the way they're hashed.

I think this is normal behavior (without really analyzing things...). See if this helps any: http://www.cisco.com/warp/customer/104/11.html Mark Radabaugh

It is normal for it to be in 2-way adjacency with with all the routers in area 0 _except_ the DR and BDR. Indeed, my Zebra forms a 2-way adjacency with all the routers in area 0, except DR and BDR, but it never even makes it to 2-way adjacency with the DR and BDR, let alone the full adjacency needed for the Zebra box to receive and inject routes into the OSPF routing table. Thanks for the link. Good info, even though not the answer to this problem. Thanks, Josh jgentry@swcp.com

The adjacency problem is fixed. We were hoping to use the Debian package for Zebra, since the Debian package management is so nice, but the packages are often old. Eventually we built the newest Zebra from source and the adjacency problem just went away. Next question. Routes from area 0 are being learned in area 51, but static routes added in area 51 are not being learned in area 0. I am using all the redistribute commands I can find.
Distrobution of routes in area 51 works fine.
Here is my config, minus auth info.

This is apparently not an appropriate topic for the nanog list. You will see no more. Thank you. Josh On Thu, Feb 07, 2002 at 11:37:35PM -0700, Josh Gentry wrote:
