FR与OSPF在P2MP网络环境中的综合使用

实验目的;配置frame-relay and ospf_p2mp 此处使用回环口模拟各分支的内网。 完成R1 R4 R5之间的全互联。

帧中继 中使用OSPF 默认使用NON-BROADCAST

此处修改为POINT-TO-MULTIPOINT(自动查找邻居,不选举DR,自动MAP) R1: Int s0/0

Ip add 145.1.1.1 255.255.255.0 No shut

Encapsulation frame-relay Frame-realy lmi-type ansi Exit

Show int s0/0 (查看二层s0/0的封装属性,验证是否已经完成了frame-relay的封装)

显示封装OK！ 进行下一步 Int loop 0

Ip add 1.1.1.1 255.255.255.0 Exit

Router ospf 110

Router-id 1.1.1.1

Network 1.1.1.0 0.0.0.255 a 0 Network 145.1.1.0 0.0.0.255 a 0 Exit

Show ip ospf inter s0/0 (查看s0/0 ospf的网络属性,在帧中继下默认是NON-BROADCAST)

此处修改ospf网络属性 为point-to-multipoint Config t Int s0/0

Ip ospf network point-to-multipoint Exit

使用show查证

OSPF网络类型修改成功。

R2与R3为运营商所属，不需要进行OSPF网络宣告。只需要配置好PVC通道 frame-relay封装 frame-relay 协议的配对。 R2 config t

no ip domain-lookup line con 0

exec-timeout 0 0 logg syn exit

frame-relay switching int s0/0

encapsulation frame-relay frame-relay lmi-type ansi frame-relay intf-type dce clock rate 64000

frame-relay route 104 interface s0/1 401 frame-relay route 105 interface tunnel2 500 no shut int s0/1

encapsulation frame-relay frame-relay lmi-type ansi frame-relay intf-type dce clock rate 64000

frame-relay route 401 interface s0/0 104 no shut int fa0/0

ip add 23.1.1.2 255.255.255.0 no shut int tunnel 2

tunnel source 23.1.1.2 tunnel des 23.1.1.3 exit R3 config t

no ip domain-lookup line con 0

exec-timeout 0 0 logg syn exit

frame-relay switching int fa0/0

ip add 23.1.1.3 255.255.255.0 no shut int tunnel 2

tunnel source 23.1.1.3 tunnel des 23.1.1.2 exit int s0/0

encapsulation frame-relay frame-relay lmi-type ansi frame-relay intf-type dce clock rate 64000

frame-relay route 501 interface tunnel2 500 no shut exit R4 config t

no ip domain-lookup line con 0

exec-timeout 0 0 logg syn

exit

int loop 0

ip add 4.4.4.4 255.255.255.0 int s0/0

ip ospf network point-to-multipoint encapsulation frame-relay frame-relay lmi-type ansi

ip add 145.1.1.4 255.255.255.0 no shut

router ospf 110 router-id 4.4.4.4

network 4.4.4.0 0.0.0.255 a 0 network 145.1.1.0 0.0.0.255 a 0 exit R5 config t

no ip domain-lookup line con 0

exec-timeout 0 0 logg syn exit

int loop 0

ip add 5.5.5.5 255.255.255.0 int s0/0

ip ospf network point-to-multipoint encapsulation frame-relay frame-relay lmi-type ansi

ip add 145.1.1.5 255.255.255.0 no shut

router ospf 110 router-id 5.5.5.5

network 5.5.5.0 0.0.0.255 a 0 network 145.1.1.0 0.0.0.255 a 0 exit

接下来进行验证。 Show ip route ospf

Ping 测试

OK.此实验已完成。 透过以上配置文件可查看,并未使用frame-relay map 进行映射。
