eigrp 认证
authentication mode hmac-sha-256 ccie key chain不同？
eigrp 认证 authentication mode hmac-sha-256 ccie key chain不同？ 命名基本配置address-family 什么情况用
DMVPN R18 D 10.2.19.0/24 [90/3097600] via 123.20.1.25, 00:00:26, Tunnel0 123.20.1.25 为什么不是123.20.1.27
水平分割的原理是 从这个端口学到的 路由条目 不再出这个端口发送出去-----防止环路 路由反射----------IBGP不许full mesh
路由策略实施后为什么R3没有123.0.0.0/8 le32的路由
没理解下面的要求 all ip add used for ebgp peering must pass the bgp's directly connected check l no bgp speaker is AS 12345 may use the network or redistribute startement under any address-family of the bgp router config
ip pim sparse-mode作用是什么
copy running-config startup-config
