排除 EIGRP 身份验证问题
RouterX 的密钥 2 改变时,RouterX 与 RouterY 之间 MD5 身份验证不成功
RouterX(config-if)#key chain RouterXchain
RouterX(config-keychain)#key 2
RouterX(config-keychain-key)#key-string wrongkey
RouterY#debug eigrp packets
EIGRP Packets debugging is on
(UPDATE, REQUEST, QUERY, REPLY, HELLO, IPXSAP, PROBE, ACK, STUB, SIAQUERY, SIAREPLY)
RouterY#
*Jan 21 16:50:: EIGRP: pkt key id = 2, authentication mismatch
*Jan 21 16:50:: EIGRP: Serial0/0/1: ignored packet from
