NA-NP-IE系列实验33:帧中继点到多点子接口
实验33:帧中继点到多点子接口
1.
实验目的
：
点到多点子接口的配置
2.
实验拓扑
3.
实验步骤
注：
“no interface s0/0/0.1”命令来删除子接口，然而需要重新启动路由
器，该子接口才真正被删除。
r0 (config)#no ip do loo
r0 (config)#lin c 0
r0(config-line)#logg s
r0(config-line)#exec-t 00
r0(config-line)#exit
r0(config)#int loo 1
*Mar 1 00:15:12.631: %LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback1, changed state to up
r0(config-if)#ip add 1.1.1 .1 255.255.255.0
r0(config)#int s0/0
r0(config-if)#no ip add
主接口下不需要IP 地址
r0(config-if)#enc fra
r0(config-if)#no frame inverse
r0(config-if)#no sh
*Mar 1 00:04:55.051: %LINK-3-UPDOWN: Interface Serial0/0, changed state to up
*Mar 1 00:05:06.055: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0, changed state to up
r0(config)#int s0/0.1 multipoint
创建点到多点子接口
