The range for setting a tag is 0 to 255 for internal routes and 0 to 4294967295 for external routes.

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.

How to Implement EIGRP

To save configuration changes, you must commit changes when the system prompts you.

Enabling EIGRP Routing

This task enables EIGRP routing and establishes an EIGRP routing process.
Before you begin
Although you can configure EIGRP before you configure an IP address, no EIGRP routing occurs until at
least one IP address is configured.
