OSPF and OSPFv3 1265
default-information
originate [always]
[metric metric-value]
[metric-type type-value]
Control the advertisement of default routes.
• always — Normally, OSPF originates a default route only
if a default route is redistributed into OSPF (and default-
information originate is configured). When the always
option is configured, OSPF originates a default route,
even if no default route is redistributed.
•
metric-value — The metric (or preference) value of the
default route. (Range: 1–16777214)
•
type-value — The value is either 1 or 2: External type-1
route or External type-2 route.
default-metric metric-
value
Set a default for the metric of distributed routes (Range:
1–16777214).
distance ospf {external |
inter-area | intra-area }
distance
Set the preference values of OSPF route types in the
router.
The range for the distance variable is 1–255. Lower route
preference values are preferred when determining the best
route.
enable Enable OSPF.
exit-overflow-interval
seconds
Specify the exit overflow interval for OSPF as defined in
RFC 1765.
The interval is the number of seconds after entering
overflow state that a router will wait before attempting to
leave the overflow state. (Range: 0–2147483647)
external-lsdb-limit limit Configure the external LSDB limit for OSPF as defined in
RFC 1765. If the value is –1, then there is no limit.
The limit variable is the maximum number of non-default
AS external-LSAs allowed in the router's link-state
database. (Range: 1 to 2147483647)
maximum-paths integer Set the number of paths that OSPF can report for a given
destination (Range: 1–4). Note: The upper limit of this
command depends on the selected SDM template. Use
show sdm prefer command to display the upper limit of
ECMP next hops.
