Configuring IPsec Authentication for an OSPFv3 Area
Prerequisite: Before you enable IPsec authentication on an OSPFv3 area, you must first enable OSPFv3
globally on the router (see
To configure IPsec authentication for an OSPFv3 area, enter the following command in global
configuration mode:
Command Syntax
area -id authentication ipsec
spi number { MD5 | SHA1 }
[key-encryption-type] key
An SPI value must be unique to one IPsec security policy (authentication or encryption) on the router. You
must configure the same authentication policy (same SPI and key) on each interface in an OPSFv3 link.
If you have enabled IPsec encryption in an OSPFv3 area with the

area authentication
The configuration of IPsec authentication on an interface-level takes precedence over an area-level
configuration. If you remove an interface configuration, an area authentication policy that has been
configured is applied to the interface.
To remove an IPsec authentication policy from an OSPFv3 area, enter the
