Enable IPv6 packet forwarding 

To enable an OSPFv3 process on a router, you need to enable the OSPFv3 process globally, assign the 

OSPFv3 process a router ID, and enable the OSPFv3 process on  related interfaces. 

A router ID uniquely identifies a router within an AS. Therefore, you need to specify a unique router ID 

for each OSPFv3 router within the AS to ensure normal operation. Note that if a router runs multiple 

OSPFv3 processes, you need to specify a unique router ID for each process.  

An OSPFv3 process ID has only local significance. Therefore, process 1 on a router can exchange 

packets with process 2 on another router. 

Follow these steps to enable OSPFv3: 

Enter system view 

— 

Enable an OSPFv3 process 
and enter its view 

ospfv3 [ process-id ]  

Required 

By default, no OSPFv3 process 
is enabled. 

Specify a router ID 

router-id router-id 

Required 

Enter interface view 

interface interface-type 
interface-number 

— 

Enable an OSPFv3 process on 
the interface 

ospfv3 process-id area area-id 
[ instance instance-id ] 

Required 

Not enabled by default 

 

The stub area and virtual link features of OSPFv3 are the same as OSPFv2. 

Splitting an OSPFv3 AS into multiple areas reduces the number of LSAs and extends OSPFv3 

applications. For those non-backbone areas residing on the AS boundary, you can configure them as 

stub areas to further reduce the size of routing tables and the number of LSAs. 

Non-backbone areas exchange routing information via the backbone area. Therefore, the backbone 

and non-backbone areas, including the backbone itself must be contiguous. In practice, necessary 

physical links may not be available for such connectivity. You can configure virtual links to address the 

problem.
