我想对 EIGRP 更新实施身份验证。
我可以在 GRE 隧道接口而不是物理接口上启用 EIGRP 身份验证吗？
GRE 隧道接口上的 EIGRP 身份验证？

是的，你可以这样做。下面是一个例子：
Router-A#
!
key chain Netlab
key 13
key-string Netlabbuilder
!
interface Tunnel1
description Site-B
ip address 10.99.99.1 255.255.255.252
ip mtu 1400
ip authentication mode eigrp 10 md5
ip authentication key-chain eigrp 10 Netlab
ip tcp adjust-mss 1360
cdp enable
tunnel source 13.1.87.2
tunnel destination 10.12.85.2
end
!
Router-A#show ip eigrp neighbors tunnel 1
IP-EIGRP neighbors for process 10
H Address Interface Hold Uptime SRTT RTO Q Seq
(sec) (ms) Cnt Num
1 10.99.99.2 Tu1 13 00:04:38 54 5000 0 17
