EIGRP v4/v6 Authentication Using Keychain
EIGRP authentication using keychain introduces the capability to authenticate EIGRP protocol packets on a
per-interface basis. The EIGRP routing authentication provides a mechanism to authenticate all EIGRP protocol
traffic on one or more interfaces, based on Message Digest 5 (MD5) authentication.
The EIGRP routing authentication uses the Cisco IOS XR software security keychain infrastructure to store
and retrieve secret keys and to authenticate incoming and outgoing traffic on a per-interface basis.
