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.

EIGRP Wide Metric Computation

The Cisco IOS XR Enhanced Interior Gateway Routing Protocol (EIGRP) implementation is enhanced to
perform wide metric computation. This enhancement is to support high bandwidth interfaces.
A new EIGRP command is added and existing EIGRP commands are enhanced to support wide metric
computation feature.
