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
encapsulation frame-relay
serial restart-delay 0
no frame-relay inverse-arp
!
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
frame-relay interface-dlci 302
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
