Connectivity Guide

3 Enter the interface information to congure the interface for OSPFv3 in INTERFACE mode.
interface ethernet node/slot/port[:subport]
4 Enable the interface in INTERFACE mode.
no shutdown
5 Disable the default switchport conguration and remove it from an interface or a LAG port in INTERFACE mode.
no switchport
6 Associate the interface with the non-default VRF instance that you created earlier.
ip vrf forwarding vrf-name
7 Enable the OSPFv3 on an interface.
ipv6 ospfv3 process-id area area-id
• process-id — Enter the OSPFv3 process ID for a specic OSPFv3 process, from 1 to 65535.
• area-id — Enter the OSPF area ID as an IP address in A.B.C.D format or number, from 1 to 65535.
Enable OSPFv3
OS10(config)# ip vrf vrf-blue
OS10(config-vrf-blue)# router ospfv3 100 vrf vrf-blue
OS10(config-router-ospfv3-100)# exit
OS10(config)# interface ethernet 1/1/2
OS10(conf-if-eth1/1/2)# no shutdown
OS10(conf-if-eth1/1/2)# no switchport
OS10(conf-if-eth1/1/2)# ip vrf forwarding vrf-blue
OS10(conf-if-eth1/1/1)# ipv6 ospfv3 300 area 0.0.0.0
Assign Router ID
You can assign a router ID for the OSPFv3 process. Congure an arbitrary value in the IP address format for each router. Each router ID
must be unique. Use the xed router ID for the active OSPFv3 router process. Changing the router ID brings down the existing OSPFv3
adjacency. The new router ID becomes eective immediately.
• Assign the router ID for the OSPFv3 process in ROUTER-OSPFv3 mode.
router-id ip-address
Assign router ID
OS10(config)# router ospfv3 100
OS10(config-router-ospfv3-100)# router-id 10.10.1.5

It is an Area Border Router
Min LSA origination 5000 msec, Min LSA arrival 1000 msec
Min LSA hold time 0 msec, Max LSA wait time 0 msec
Number of area in this router is 2, normal 2 stub 0 nssa
Area (0.0.0.0)
Number of interface in this area is 1
SPF algorithm executed 42 times
Area (0.0.0.1)
Number of interface in this area is 1

Congure Stub Areas
Type 5 LSAs are not ooded into stub areas. The ABR advertises a default route into the stub area where it is attached. Stub area routers
use the default route to reach external destinations.
