292 • To implement area-based IPsec protection, you need to configure the same IPsec policy on the routers in the target area. • To implement interface-based IPsec protection, you need to configure the same IPsec policy on the interfaces between two neighboring routers. • To implement virtual link-based IPsec protection, yo u n e e d t o c o n fig u re t h e s a m e I Ps e c p o l ic y o n t h e two routers connected over the virtual link. If an interface and its area each have an IPsec poli cy configured, the interface uses its own IPsec policy. If a virtual link and area 0 each have an IPsec policy configured, the virtual link uses its own IPsec policy. Configuration prerequisites Before you apply an IPsec policy for OSPFv3, complete following tasks. • Create an IPsec proposal. • Create an IPsec policy. For more information about IPsec policy configuration, see Security Configuration Guide. Configuration guidelines An IPsec policy used for OSPFv3 can only be in manual mode.

Configuring OSPFv3 areas
Network requirements
In Figure 107 , all s witches run OSPFv3. The AS is split into three areas, in which, Switch B and Switch C
act as ABRs to forward routing information between areas.
Configure Area 2 as a stub area in order to reduce LSAs in the area without affecting route reachability.

Configuring OSPFv3 DR election
Network requirements
As shown in Figure 108:
• T
he priority of Switch A is 100, the highest priority on the network, so it will be the DR.
• The priority of Switch C is 2, the second highest priority on the network, so it will be the BDR.
• The priority of Switch B is 0, so it cannot become the DR.
• Router D has the default priority 1.

Configuring OSPFv3 route redistribution
Network requirements
As shown in Figure 109:
• S
witch A, Switch B, and Switch C are in Area 2.
• OSPFv3 process 1 and OSPFv3 process 2 are enabled on Switch B. Switch B communicates with
Switch A and Switch C through OSPFv3 process 1 and OSPFv3 process 2.
Configure OSPFv3 process 2 to redistribute direct routes and the routes from OSPFv3 process 1 on
Switch B and set the default metric for redistributed routes to 3. Then, Switch C can learn the routes
destined for 1::0/64 and 2::0/64, and Switch A ca nnot learn the routes destined for 3::0/64 or
4::0/64.
