Chapter 6 Configuring OSPFv2
Configuring Advanced OSPFv2
Create the necessary route maps used for redistribution.
Ensure that you are in the correct VDC (or use the switchto vdc command).
SUMMARY STEPS
1. config t
2. router ospf instance-tag
3. redistribute {bgp id | direct | eigrp id | isis id | ospf id | rip id | static} route-map map-name
4. default-information originate [always] [route-map map-name]
5. default-metric cost
6. exit
7. copy running-config startup-config
DETAILED STEPS
Command Purpose
Step 1
config t
Example:
switch# config t
switch(config)#
Enters configuration mode.
Step 2
router ospf instance-tag
Example:
switch(config)# router ospf 201
switch(config-router)#
Creates a new OSPFv2 instance with the configured
instance tag.
Step 3
redistribute {bgp id | direct | eigrp id
| isis
id | ospf id | rip id | static}
route-map
map-name
Example:
switch(config-router)# redistribute bgp
route-map FilterExternalBGP
Redistributes the selected protocol into OSPF through
the configured route map.
Note If you redistribute static routes, Cisco NX-OS
also redistributes the default static route.
Step 4
default-information originate [always]
[route-map map-name]
Example:
switch(config-router)#
default-information-originate route-map
DefaultRouteFilter
Creates a default route into this OSPF domain if the
default route exists in the RIB. Use the following
optional keywords:
• always —Always generate the default route of
0.0.0. even if the route does not exist in the RIB.
• route-map—Generate the default route if the
route map returns true.
Note This command ignores match statements in
the route map.
