帧中继动态映射与静态映射主要区别

帧中继动态映射与静态映射主要区别现在的理解是：

1.动态映射：frame-relay inverse-arp (这个是默认配置) 它会自动将PVC另一端的设备的IP地址映射到本地DLCI。（在做实验时，最好先clear frame-relay inarp 删除映射表）

2.静态映射当然就要自己配置了，在配置静态映射时，切记要在接口下 no frame-relay inverse-arp 然后根据命令：frame-relay map protocol protocol-address dlci [broadcast] [ietf | cisco ] [payloadompress { packet-by-packet | frf9 stac} ]

动态映射中R2,R3没有建立邻居关系。（逆向ARP并不提供让路由器R2和R3能够相互通信的动态映射，因为它们并不是通过PVC相连的，必须要手工配置它们）

R1:

ena
conf t
frame-relay sw
int s0/0
enca frame-relay
frame-relay intf-type dce
frame-relay route 102 int s0/1 100
frame-relay route 103 int s0/2 130
clock rate 64000
no sh

int s0/1
enca frame-relay
frame-relay intf-type dce
frame-relay route 100 int s0/0 102
clock rate 64000
no sh

int s0/2
enca frame-relay
frame-relay intf-type dce
frame-relay route 130 int s0/0 103

clock rate 64000
no sh

R2:

ena
conf t
int s0/0
enca frame-relay
frame-relay inter 102
frame-relay inter 103
ip add 192.168.1.101 255.255.255.0
no sh
exit

router eig 1
network 192.168.1.0 0.0.0.255

network 172.16.1.0 0.0.0.255

no au
exit
int f1/0
ip add 172.16.1.2 255.255.255.0
no sh

R3:

ena
conf t
int s0/0
enc frame-re
frame-re inte 100
ip add 192.168.1.102 255.255.255.0
no sh
exit
router eig 1
netw 192.168.1.0 0.0.0.255

no au

R4:

ena
conf t
int s0/0
enc frame-re
frame-re inte 130
ip add 192.168.1.103 255.255.255.0
no sh
exit
router eig 1
netw 192.168.1.0 0.0.0.255

no au

R5:

ena
conf t
int f0/0
ip add 172.16.1.1 255.255.255.0
no sh
exit
router eig 1
netwo 172.16.1.0 0.0.0.255

no au

在上面的基础上改成静态：

end

conf t

int s0/0

no frame-relay inv

end

clear frame-relay inarp

conf t

int s0/0

frame-relay map ip 192.168.1.101 101

frame-relay map ip 192.168.1.102 102 bro

frame-relay map ip 192.168.1.103 103 bro

end

conf t

int s0/0

no frame-relay inv

end

clear frame-relay inarp

conf t

int s0/0

frame-relay map ip 192.168.1.101 100 bro

frame-relay map ip 192.168.1.103 100 bro

R4:

end

conf t

int s0/0

no frame-relay inv

end

clear frame-relay inarp

conf t

int s0/0

frame-relay map ip 192.168.1.101 130 bro

frame-relay map ip 192.168.1.102 130 bro
