Applying IPsec policies for OSPFv3
To protect routing information and defend attacks, OSPFv3 can authenticate protocol packets by using
an IPsec policy.
Outbound OSPFv3 packets carry the Security Parameter Index (SPI) defined in the relevant IPsec policy.
A device uses the SPI carried in a received packet to match against the configured IPsec policy. If they
match, the device accepts the packet. Otherwise, it discards the packet and will not establish a neighbor
relationship with the sending device.
You can configure an IPsec policy for an area, an interface, or a virtual link.
• To implement area-based IPsec protection, configure the same IPsec policy on the routers in the
target area.
• To implement interface-based IPsec protection, configure the same IPsec policy on the interfaces
between two neighboring routers.
• To implement virtual link-based IPsec protection, configure the same IPsec policy on the two routers
connected over the virtual link.
If an interface and its area each have an IPsec policy 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 applying an IPsec policy for OSPFv3, complete the following tasks:
• Create an IPsec proposal.
• Create an IPsec policy.
For more information about IPsec policy configuration, see Security Configuration Guide.
Configuration procedure
An IPsec policy used for OSPFv3 can only be in manual mode. For more information, see Security
Configuration Guide.
