Hi K,

Hi John,

I'm failing to get the full picture of the situation. 
Short from the fact that I'm contracting a headache from trying to read 
the logs :-)
Maybe I could help if you could provide the configs of 
the ports and maybe supply the output of the commands and log with 
proper formatting. Also, throw in a "show ip ospf" in there.

Rgds,

K

No  - We have a working ospf adj between FA3/0(R1), and a vlan/dot1q subint /30(R2) via provider A

No - We have a new link (/30) new vlan from new provider, same vlan at both ends(As dot1q subints) that is going up/down every ~60sec

We have 2 links, both /30's, one (working) is handed of via vlan at R2(Which is portchan dot1q subint), the other is physical int FA3/0, the one that is up/down, is handed off via different provider, same vlan at each end, and as portchan dot1q subints.

Hope that makes sense?
