[執行個體]H&M SH office 2 IP位址區段擴容

SH office 2以前使用10.200.4.0網段,現需求擴大IP 位址段.

方法1:更改mask,但這個會影響到目前所有裝置的更改及地址規劃等問題

方法2: 添加一個新的IP位址區段給sh office 2使用

現在我們就來實現方法2

1-構建MPLS網路

SH office 2與 SH office1 通過 MPLS 串連,R6有環回口6.6.6.6

R1-R4跑的是靜態路由 <類比現狀>

R6-R5 跑得是OSPF

1-1察看VRF資訊

R4#sh ip vrf detail

VRF mpls14 (VRF Id = 1); default RD 1:1; default VPNID <not set>

Interfaces:

Fa0/1

VRF Table ID = 1

Export VPN route-target communities

RT:16:16

Import VPN route-target communities

RT:16:16

No import route-map

No export route-map

VRF label distribution protocol: not configured

VRF label allocation mode: per-prefix

R4#sh ip vrf interfaces

Interface IP-Address VRF Protocol

Fa0/1 14.1.1.4 mpls14 up

1-2察看VRF路由

R4#sh ip route vrf mpls14

Gateway of last resort is 14.1.1.1 to network 0.0.0.0

S* 0.0.0.0/0 [1/0] via 14.1.1.1, FastEthernet0/1

6.0.0.0/32 is subnetted, 1 subnets

B 6.6.6.6 [200/2] via 5.5.5.5, 00:11:54

14.0.0.0/8 is variably subnetted, 2 subnets, 2 masks

C 14.1.1.0/24 is directly connected, FastEthernet0/1

L 14.1.1.4/32 is directly connected, FastEthernet0/1

56.0.0.0/24 is subnetted, 1 subnets

B 56.1.1.0 [200/0] via 5.5.5.5, 00:11:54

R5#sh ip route vrf mpls56

Gateway of last resort is 4.4.4.4 to network 0.0.0.0

B* 0.0.0.0/0 [200/0] via 4.4.4.4, 00:12:32

6.0.0.0/32 is subnetted, 1 subnets

O 6.6.6.6 [110/2] via 56.1.1.6, 00:12:48, FastEthernet0/0

56.0.0.0/8 is variably subnetted, 2 subnets, 2 masks

C 56.1.1.0/24 is directly connected, FastEthernet0/0

L 56.1.1.5/32 is directly connected, FastEthernet0/0

2-構建單臂路由

主要是在R1的F0/0 介面下配置

interface FastEthernet0/0

no ip address

duplex auto

speed auto

!

!

interface FastEthernet0/0.1

encapsulation dot1Q 1 native

ip address 10.200.4.254 255.255.255.0

!

interface FastEthernet0/0.2

encapsulation dot1Q 2

ip address 10.200.43.254 255.255.255.0

!

interface FastEthernet0/1

ip address 14.1.1.1 255.255.255.0

duplex auto

speed auto

SW1---R1 之間為trunk鏈路 SW3-SW2之間為trunk鏈路

測試結果就是:

PC9-PC8-PC7 可以相互ping通,且都可以ping通6.6.6.6
