1. Experimental Topology

2. Authentication supported by each routing protocol

EIGRP only supports MD5 authentication and is port-based authentication.

3. Basic configuration

R2

Interface Serial0/1

Ip address 23.1.1.2 255.255.255.0

Router eigrp 90

Network 23.1.1.0 0.0.0.255

No auto-summary

R3

Interface Serial0/1

Ip address 23.1.1.3 255.255.255.0

Router eigrp 90

Network 23.1.1.0 0.0.0.255

No auto-summary

4. MD5 authentication configuration

The general process of MD5 certification:

First define a key chain, then define a key in the key chain, and finally enable MD5 authentication and invoke the key chain on the interface. 、

R2

Key chain R2

Key 1

Key-string cisco

Ip authentication key-chain eigrp 90 R2

R3

Key chain R3

Key 1

Key-string cisco

Interface Serial0/1

Ip authentication mode eigrp 90 md5
