[c-nsp] Odd behavior: OSPF on a physical port of an SVI

[Leah Lynch (Contractor)]

Are you absolutely sure that MD5 key is the same on all routers?

I can't even think of what the magic google/cco-fu would be to look for
this.


7609-S with Sup720-3BXL running 12.2(18)SXF16 with a WS-X6516-GE-TX.


All ports on the 6516 are configured in the same VLAN (using "interface
range...") as access ports:
---
 switchport
 switchport access vlan 3
 switchport mode access
 no ip address
---
interface Vlan3
 ip address X.Y.Z.5 255.255.255.0
 ip flow ingress
 ip ospf authentication
 ip ospf authentication-key 7 <KEY>
 ip ospf priority 0
 hold-queue 1000 in
---

A 7500 attached to one port (jack 6) will only form OSPF associations
with
1-3 neighbors (out of about 30).  To add to the joy, the other devices
see
the 7500 as a neighbor.  If I move another 7500 onto the port, it has
the
same behavior.  The original 7500 on another port works fine. ARP and
basic
IP (ping) work regardless of port.

My immediate reaction is a bad port on the blade, but a) IP passes, and
b)
"it's just a 16 port switch"; the brains are on the SVI.


Any clues for additional troubleshooting?

Thanks,
