What if you where to use a loopback interface instead of the router-id. It
might be worth a shot.

Subject: RE: OSPF neighbor problem
Thanks all for all the response and good advices. this is what i've done:
1. the routers have been rebooted before i posted for help
2. they are up for over 10 hours now, and still doing the same thing.
3. they can ping each other over the e0/0 and f0/0.
4. they are both using ios 12.2(7a), see below show version
5. both intf's are plugged in Cat3548's f0/4 and f0/7 and vlan'ed in vlan8:
#show cdp d
r3 Fas 0/4 169 R 2612 Eth 0/0
r5 Fas 0/7 124 R 2621 Fas 0/0
#show vlan
8 VLAN0008 active Fa0/4, Fa0/6, Fa0/7, Fa0/9
6. i don't think it's hardware problem, and routers, intf's, cat3548 have
been working fine.
7. as to Guy Lupi's advice, I used half-duplex before and changed it to
full, to no joy.
now what? ;-)
