Browse Source 
2006-07-10 Paul Jakma <paul.jakma@sun.com>

	* ospf_nsm.c: (ospf_nsm_event) Record state change timestamp
	  and event in nbr struct.
	* ospf_neighbor.h: (struct ospf_neighbor) Add fields to record
	  timestamp of last NSM change and event.
	* ospf_vty.c: (show_ip_ospf_neighbor_detail_sub) Print
	  last state change timestamp and event, if available.
