Chapter 7 Configuring OSPFv3
Configuring Advanced OSPFv3
DETAILED STEPS
The following example shows how to create summary addresses between areas on an ABR:
switch# config t
switch(config)# router ospfv3 201
switch(config-router)# address-family ipv6 unicast
switch(config-router)# area 0.0.0.10 range 2001:0DB8::/48
switch(config-router)# copy running-config startup-config
The following example shows how to create summary addresses on an ASBR:
switch# config t
switch(config)# router ospf 201
switch(config-router)# address-family ipv6 unicast
switch(config-router)# summary-address 2001:0DB8::/48
switch(config-router)# copy running-config startup-config
Command Purpose
Step 1
config t
Example:
switch# config t
switch(config)#
Enters configuration mode.
Step 2
router ospfv3 instance-tag
Example:
switch(config)# router ospfv3 201
switch(config-router)#
Creates a new OSPFv3 instance with the configured
instance tag.
Step 3
address-family ipv6 unicast
Example:
switch(config-router)# address-family
ipv6 unicast
switch(config-router-af)#
Enters IPv6 unicast address family mode.
Step 4
area area-id range ipv6-prefix/length
[no-advertise]
Example:
switch(config-router-af)# area 0.0.0.10
range 2001:0DB8::/48 advertise
Creates a summary address on an ABR for a range of
addresses. Optionally advertises this summary address
in a Inter-Area Prefix (type 3) LSA.
Step 5
summary-address ipv6-prefix/length
[no-advertise][tag
tag ]
Example:
switch(config-router-af)#
summary-address 2001:0DB8::/48 tag 2
Creates a summary address on an ASBR for a range of
addresses and optionally assigns a tag for this
summary address that can be used for redistribution
with route maps.
Step 6
show ipv6 ospfv3 summary-address
Example:
switch(config-router)# show ipv6 ospfv3
summary-address
(Optional) Displays information about OSPFv3
summary addresses.
Step 7
copy running-config startup-config
Example:
switch(config-router)# copy
running-config startup-config
(Optional) Saves this configuration change.
