Chapter 7 Configuring OSPFv3
Configuring Advanced OSPFv3
The following example shows how to create an NSSA that filters external routes and blocks all summary
route updates:
switch# config t
switch(config)# router ospfv3 201
switch(config-router)# area 0.0.0.10 nssa route-map ExternalFilter no-summary
switch(config-router)# copy running-config startup-config
The following example shows how to create an NSSA that always translates Type-7 LSAs to AS External
(type 5) LSAs:
switch# config t
switch(config)# router ospfv3 201
switch(config-router)# area 0.0.0.10 nssa translate type 7 always
switch(config-router)# copy running-config startup-config
The following example shows how to create an NSSA that blocks all summary route updates:
switch# config t
switch(config)# router ospfv3 201
switch(config-router)# area 0.0.0.10 nssa no-summary
switch(config-router)# copy running-config startup-config
Configuring Multi-Area Adjacency
You can add more than one area to an existing OSPFv3 interface. The additional logical interfaces
support multi-area adjacency.
BEFORE YOU BEGIN
Ensure that you have enabled the OSPFv3 feature (see the “Enabling the OSPFv3 Feature” section on
page 7-13).
Ensure that you are in the correct VDC (or use the switchto vdc command).
Ensure that you have configured a primary area for the interface (see the “Configuring Networks in
OSPFv3” section on page 7-17
SUMMARY STEPS
1. config t
2. interface interface-type slot/port
3. ipv6 router ospfv3 instance-tag multi-area area-id
4. show ipv6 ospfv3 instance-tag interface interface-type slot/port
5. copy running-config startup-config
