Table 6: show ip ospf - display description
Field Description
Routing Process
with ID
OSPF process ID 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
Conforms to
RFC2328
Shows that this router is compliant with OSPF Version 2.
RFC1583
Compatibility
flag
Shows whether or not compatibility with the RFC 1583 (an earlier version of
OSPFv2) is enabled.
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
Delay between receiving a change to SPF calculation.
Hold time Sets the hold time between two consecutive SPF calculations.
Refresh timer The time between refreshing the LSA database.
Number of
current 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.
Number of
opaque AS LSA
Number of opaque link-state advertisements (Type 9, 10 and 11 LSAs) in 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
overflow limit
The maximum number of LSAs allowed in the external database.
