RE: OSPFv3 Neighbor Stuck in EXSTART/EXCHANGE

Capture the OSPF traffic between the devices and check the options of the DBD packets.

Subject: OSPFv3 Neighbor Stuck in EXSTART/EXCHANGE

Hi,

I am trying to bring up the ospfv3 IPv6 neighboring between Cisco Cat6k5 and Quagga, the neighbor relationship is stuck in EXSTART/EXCHANGE state, I have checked the link http://cisco.iphelp.ru/faq/5/ch09lev1sec6.html ; but it seems to me that the problem is not from this list.

The neighbor with other vendors devices (Juniper, Brocade) is ok .

On the Cisco Cat, I have the result of debug: "EXCHANGE - OPTIONS/INIT not match" although I have check for MTU, RouterID.
