Chapter 7 Configuring OSPFv3
Configuring Advanced OSPFv3
DETAILED STEPS
The following example shows how to add a second area to an OSPFv3 interface:
switch# config t
switch(config)# interface ethernet 1/2
switch(config-if)# ipv6 address 2001:0DB8::1/48
switch(config-if)# ipv6 ospfv3 201 area 0.0.0.10
switch(config-if)# ipv6 ospfv3 201 multi-area 20
switch(config-if)# copy running-config startup-config
Configuring Virtual Links
A virtual link connects an isolated area to the backbone area through an intermediate area. See the
“Virtual Links” section on page 7-10. You can configure the following optional parameters for a virtual
link:
• Dead interval—Sets the time that a neighbor waits for a Hello packet before declaring the local
router as dead and tearing down adjacencies.
• Hello interval—Sets the time between successive Hello packets.
• Retransmit interval—Sets the estimated time between successive LSAs.
• Transmit delay—Sets the estimated time to transmit an LSA to a neighbor.
Command Purpose
Step 1
config t
Example:
switch# config t
switch(config)#
Enters configuration mode.
Step 2
interface interface-type slot/port
Example:
switch(config)# interface ethernet 1/2
switch(config-if)#
Enters interface configuration mode.
Step 3
ipv6 router ospfv3 instance-tag
multi-area area-id
Example:
switch(config-if)# ipv6 router ospfv3
201 multi-area 3
Adds the interface to another area.
Step 4
show ipv6 ospfv3 instance-tag interface
interface-type slot/port
Example:
switch(config-if)# show ipv6 ospfv3 201
interface ethernet 1/2
(Optional) Displays OSPFv3 information.
Step 5
copy running-config startup-config
Example:
switch(config)# copy running-config
startup-config
(Optional) Saves this configuration change.
