has anyone ever had an issue where adding a vlan to a core 6509 (VTP server) has caused OSPF adjacencies to flap, the vlan created does not have any host associated to it, it was just created,on the core switch and this appears to have caused an OSPF neighbor to go down along with 10 vlans. About 2 mins later all adjacencies came back online. Prior to this, the network had been stable the only recent change was the addition of a vlan,
the core switch is the only VTP server, all other switches are all in client mode and part of the same VTP Domain/password.
it might be a IOS,bug current IOS is (s3223_rp-ADVENTERPRISEK9_WAN-M), Version 12.2(33)SXH3a
loggin history shows error below, after OSPF came back up, vlans started to come back up as well, link on opposite side, only shows OSPF neighbor droping,
