FR实验
实验目的：今天突然想到很久没做过FR的实验，就顺手把FR的实验做了下 就当是做一个复习 有什么不对的地方 请大家帮忙指出来
一：总拓扑
这个拓扑是有用到的只是 R1 R2和R3三个路由器实验一：帧中继点到点子接口
R1
!
interface Serial2/0
no ip address
encapsulation frame-relay
serial restart-delay 0
no frame-relay inverse-arp
!
interface Serial2/0.1 point-to-point
ip address 12.12.12.1 255.255.255.0
frame-relay interface-dlci 102
!
interface Serial2/0.2 point-to-point
ip address 13.13.13.1 255.255.255.0
frame-relay interface-dlci 103
R2
!
interface Serial2/0
no ip address
encapsulation frame-relay
serial restart-delay 0
no frame-relay inverse-arp
!
interface Serial2/0.1 point-to-point
ip address 12.12.12.2 255.255.255.0
frame-relay interface-dlci 201
!
interface Serial2/0.2 point-to-point
ip address 23.23.23.2 255.255.255.0
frame-relay interface-dlci 203
!
R3
interface Serial2/0
no ip address
serial restart-delay 0
!
interface Serial2/0.1 point-to-point
ip address 13.13.13.3 255.255.255.0
frame-relay interface-dlci 301
!
interface Serial2/0.2 point-to-point
ip address 23.23.23.3 255.255.255.0
三：解释
在这里 首先要在接口下开启帧中继encapsulation frame-relay 但是不要配置ip地址 取消反向arp --no frame-relay inverse-arp
接下来就在各个子接口下配置ip 和配置dlci ---frame-relay interface-dlci XX 在这里值得说明的一点是 每个子接口对应的端口地址要在同一网段中
实验二：帧中继点到多点子接口和点到点子接口相混合
一：实验环境
1）R1上起两个子接口s2/0.1 ,s2/0.2 R2 R3 R4各起一个子接口 s2/0.1 同时R1的s2/0.1分别与R2 R4的s2/0.1做点到多点连接 网段为124.1.1.0/24。R1的s2/0.2和R3的s2/0.1 做点到点相连 网段为：13.13.13.0/24
2）在R1 R2 R4上各起一个loopback0 ，起协议为ospf ，R1和R3上再起一个rip协议 最后做重发布
二：配置

三：解释
1）在配置帧中继的时候要主要的一点就是类型 如lmi 在cisco里面 默认的类型都是为cisco 类型是可以改的 一般配置的时候我都是会将类型统一为国际标准 frame-relay lmi-type ansi 排错的时候可以用到的命令为sh frame-relay lmi
show frame-relay pvc
show fram map
2）配置协议的时候，像ospf就比较特殊必须在接口下输入ip ospf network point-to-multipoint来修改接口的类型 如果这条命令不打进去 show ip route的时候看不到其他路由器的路由
完整的路由应该为
协议排错命令可以为
sh ip os neighbor
Sh ip ospf interface
