frame relay
nbma网络没有广播多路访问网络
静态map
动态map
帧中继拓扑结构
full全互联(不建议使用)
部分互联
hub and spoke一个中心多个分支
eigrp工作帧中继网络
hello包围60s
holdtime为180s
fr接口
1.物理接口
2.点到点子接口
3.多点子接口
eigrp unicast 邻居
neighbor 1.1.1.1
微调eigrp
默认情况下,eigrp会使用不超过50%的接口带宽来传输eigrp信息
ip bandwidh-percent eigrp as-number percent
修改eigrp接口占用带宽
int s0/0
bandwidth 64
ip bandwidth-percent eigrp 1 50
eigrp在广域网问题
实验:
ip地址分配情况:r1-r2-r3=123.1.1.0/24,r2-r3-r4=10.1.234.0/24,r4-r5=45.1.1.0/24
如:r2-f0/0=10.1.234.2/24,r5-s1/3=45.1.1.5/24
其他网段ip地址配置同理,每台路由器各有一个lo0
其他网段ip地址配置同理,每台路由器各有一个lo0,
地址分配是:x.x.x.x/24(x是你的路由器号),在r1上添加4个换回接口,模拟r1连接内网4个部门网关:
lo4:172.16.4.1/24
lo5:172.16.5.1/24
lo6:172.16.6.1/24
lo7:172.16.7.1/24
use the following requirements to configure r1 and r2 and r3 for frame relay and r4(r4作为帧中继交换机,r1,r2,r3连入到这个帧中继交换机)
as the frame relay switch.(r4_s1/0,s1/1,s1/2,s1/3为dce端)
use ansi lmi on frame relay switch and auto-sensing on r1 and r2
do not use inverse address resolutions protocol and after finishing your lab you haven't got any dynamlc maps and maps of 0.0.0.0
use rfc1490/rfc2427 encapsulation
use the data-link connection identifier(dlci)assignments from the top
r1使用frame-relay接口ip地址,而r2/r3使用frame-relay点到点子接口建立连接,要求完成此配置后能。
ping通各自的frame-relay接口ip地址(r2/r3 do not use any static frame relay maps)

帧中继多点子接口,常出现路由问题,没法办学全路由,水平分割问题。eigrp工作在物理接口上水平分割是起作用的。rip是多点子接口会有水平分割问题。
r1:
关闭水平分割
no ip split-horizon eigrp 100
