PurposeCommand or Action
Example:
RRP/0/RSP0/CPU0:router(config-ospf)# router-id
192.168.4.3
We recommend using a stable IPv4 address as the router
ID.
Note
Redistributes OSPF routes from one routing domain to another
routing domain.
redistribute protocol [ process-id ] { level-1 | level-1-2
| level-2 } [ metric metric-value ] [ metric-type
Step 4
type-value ] [ match { external [ 1 | 2 ]} [ tag tag-value
] [ route-policy policy-name ]
or
Redistributes OSPFv3 routes from one routing domain to another
routing domain.
Example:
RP/0/RSP0/CPU0:router(config-ospf)# redistribute
bgp 100
•
This command causes the router to become an ASBR by
definition.
or
RP/0/RSP0/CPU0:router(config-router)#redistribute
bgp 110
•
OSPF tags all routes learned through redistribution as
external.
•
The protocol and its process ID, if it has one, indicate the
protocol being redistributed into OSPF.
•
The metric is the cost you assign to the external route. The
default is 20 for all protocols except BGP, whose default
metric is 1.
•
The OSPF example redistributes BGP autonomous system
1, Level 1 routes into OSPF as Type 2 external routes.
•
The OSPFv3 example redistributes BGP autonomous
system 1, Level 1 and 2 routes into OSPF. The external
link type associated with the default route advertised into
the OSPFv3 routing domain is the Type 1 external route.
RPL is not supported for
OSPFv3.
Note
(Optional) Creates aggregate addresses for OSPF.Do one of the following:
Step 5
or
•
summary-prefix address mask [ not-advertise
] [ tag tag ]
(Optional) Creates aggregate addresses for OSPFv3.
•
summary-prefix ipv6-prefix / prefix-length [
not-advertise ] [ tag tag ]
•
This command provides external route summarization of
the non-OSPF routes.
•
External ranges that are being summarized should be
contiguous. Summarization of overlapping ranges from
Example:
RP/0/RSP0/CPU0:router(config-ospf)# summary-prefix
10.1.0.0 255.255.0.0
two different routers could cause packets to be sent to the
wrong destination.
or
RP/0/RSP0/CPU0:router(config-router)#
summary-prefix 2010:11:22::/32
•
This command is optional. If you do not specify it, each
route is included in the link-state database and advertised
in LSAs.
