Table 18: show ip ospf - display description
Field Description
Routing Process
Routing Process OSPF process name and router ID. The router ID uniquely identifies the router in
the autonomous system. By convention, this is normally set to one of the router's
IP interface addresses.
Process uptime The time this process has been running
Supports only
single TOS (TOS0)
routes
Optional Type of Service (ToS) specified in OSPF Version 2, Appendix F.1.2 is not
supported, so only one cost per interface can be assigned.
SPF schedule
delay
The delay after receiving a topology change notification and starting the SPF
calculation.
Hold time Sets the hold time between two consecutive SPF calculations.
Number of
concurrent DD
exchange
neighbors
Number of neighbors currently exchanging database descriptor packets.
Number of
external LSA
The number of external link-state advertisements (Type 5 LSAs) in the link-state
database. These LSAs advertise information about routes outside of the
autonomous system.
Checksum The sum of the LS checksums of the external link-state advertisements contained
in the link-state database.
