I just gave this a shot, but still no success. Thanks for the response,
though. Allyn

Subject: EIGRP over ATM

I ran into a problem today that I can't seem to resolve. I am experiencing
a problem with EIGRP neighbors staying up over an ATM link when using either
PVCs, SVCs or classical IP. The symptoms are exactly the same for all of
these. However, I'm not having problems with other routing protocols. The
neighbors will come up for 5 seconds, go down for 5 seconds. I do see
hellos on both routers, though:

01:31:58: EIGRP: Sending HELLO on ATM3/0 nbr 172.32.1.15
01:31:58: AS 10, Flags 0x0, Seq 0/0 idbQ 0/0 iidbQ un/rely 0/0
01:31:59: EIGRP: Received HELLO on ATM3/0 nbr 172.32.1.15
01:31:59: AS 10, Flags 0x0, Seq 0/0 idbQ 0/0
01:32:03: EIGRP: Sending HELLO on ATM3/0 nbr 172.32.1.15

The routers are running 12.0.7T, and I reloaded them and the ATM switch a
couple of times. Do any of you have an idea that I might try? Incidentally,
both routers (at least for the PVC configuration) are configured as follows,
only the IP and PVC information is changed between the two:

interface ATM3/0
 bandwidth 155000
 ip address 172.32.1.16 255.255.255.0
 ip directed-broadcast
 no ip route-cache
 no ip mroute-cache
 no atm ilmi-keepalive
 pvc toR15 1/116
  protocol ip 172.32.1.15
  broadcast

router eigrp 10
 network 172.22.0.0
 network 172.32.0.0
 neighbor 172.32.1.15 ATM3/0
 no auto-summary

Thanks - Allyn
