Field
Description
Routing Process
OSPF process ID and router ID. The router ID uniquely identifies the router
with ID
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
Conforms to
Shows that this router is compliant with OSPF Version 2.
RFC2328
RFC1583
Shows whether or not compatibility with the RFC 1583 (an earlier version
Compatibility
of OSPFv2) is enabled.
flag
Supports only
Optional Type of Service (ToS) specified in OSPF Version 2, Appendix F.1.2
single TOS
is not supported, so only one cost per interface can be assigned.

SPF schedule
Delay between receiving a change to SPF calculation.
delay
Hold time
Sets the hold time between two consecutive SPF calculations.
Refresh timer
The time between refreshing the LSA database.
Number of
Number of neighbors currently exchanging database descriptor packets.
current DD
exchange
neighbors
Number of
The number of external link-state advertisements (Type 5 LSAs) in the link-
external LSA
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.
Number of
Number of opaque link-state advertisements (Type 9, 10 and 11 LSAs) in
opaque AS LSA
the link-state database. These LSAs advertise information about external
applications, and are only used by OSPF for the graceful restart process.
Checksum
The sum of the LS checksums of opaque link-state advertisements
contained in the link-state database.
LSDB database
The maximum number of LSAs allowed in the external database.
overflow limit
Number of LSA
The number of new link-state advertisements that have been originated.
originated
Number of LSA
The number of link-state advertisements that have been received.
