4. Apply the IPsec policies in areas:
# Configure Router A.
[RouterA] ospfv3 1
[RouterA-ospfv3-1] area 1
[RouterA-ospfv3-1-area-0.0.0.1] enable ipsec-policy policy001
[RouterA-ospfv3-1-area-0.0.0.1] quit
[RouterA-ospfv3-1] quit
# Configure Router B.
[RouterB] ospfv3 1
[RouterB-ospfv3-1] area 0
[RouterB-ospfv3-1-area-0.0.0.0] enable ipsec-policy policy002
[RouterB-ospfv3-1-area-0.0.0.0] quit
[RouterB-ospfv3-1] area 1
[RouterB-ospfv3-1-area-0.0.0.1] enable ipsec-policy policy001
[RouterB-ospfv3-1-area-0.0.0.1] quit
[RouterB-ospfv3-1] quit
# Configure Router C.
[RouterC] ospfv3 1
[RouterC-ospfv3-1] area 0
[RouterC-ospfv3-1-area-0.0.0.0] enable ipsec-policy policy002
[RouterC-ospfv3-1-area-0.0.0.0] quit
[RouterC-ospfv3-1] quit
5. Verify the configuration:
OSPFv3 traffic between Routers A, B and C is protected by IPsec.
Troubleshooting OSPFv3 configuration
No OSPFv3 neighbor relationship established
Symptom
No OSPF neighbor relationship can be established.
Analysis
If the physical link and lower protocol function properly, check OSPF parameters configured on interfaces.
The two neighboring interfaces must have the same parameters, such as the area ID, network segment
and mask and network type. If the network type is broadcast, at least one interface must have a DR
priority higher than 0.
Solution
1. Display neighbor information using the display ospfv3 peer command.
2. Display OSPFv3 interface information using the display ospfv3 interface command.
3. Ping the neighbor router’s IP address to check connectivity.
4. Check OSPF timers. The dead interval on an interface must be at least four times the hello interval.
