ip ospf authentication keychain

Configures Open Shortest Path First version 2 (OSPFv2) authentication using the keychain authentication module.
Syntax
ip ospf authentication keychain keychain-name
no ip ospf authentication keychain keychain-name
Parameters
keychain-name
Specifies the name of the keychain that OSPFv2 uses to authenticate the packets.

Usage Guidelines

The keychain authentication module provides the OSPFv2 protocol the option to automatically change the key ID and cryptographic algorithm without manual intervention.

With this configuration, OSPFv2 requests the keychain authentication module for all active keys in the keychain and selects the keys for sending and accepting the packets.

The no form of the command removes keychain authentication from the OSPFv2 interface configuration.

Examples

The following example configures OSPFv2 to use the keychain authentication module with the "xtreme" keychain. 

device# configure terminal
device(config)# interface ve 1
device(config-vif-11)# ip ospf authentication keychain xtreme
