基於幀中繼的ospf/ospfv3配置

一．拓撲圖

 

二．網段分配

 

R1	S1/0	192.168.43.1/24	R6	F1/0	10.43.30.1/24
R2	S1/0	192.168.43.2/24	R7	F1/0	10.43.20.2/24
R3	幀中繼無地址			F0/0	10.43.30.2/24
R4	S1/0	192.168.43.4/24		F0/1	10.43.40.2/24
	F0/0	10.43.10.1/24	R8	F0/1	10.43.40.1/24
R5	F0/0	1.43.10.2/24
	F0/1	10.43.20.1/24
R6	F0/0	10.43.10.3/24
本地還回地址
R1		1.1.1.1/24	R6		5.5.5.5/24
R2		2.2.2.2/24	R7		6.6.6.6/24
R4		3.3.3.3/24	R8		7.7.7.7/24
R5		4.4.4.4/24

三．配置過程

（1）幀中繼部分

R4：

interface Loopback0

    ip address 3.3.3.3 255.255.255.0

    ip ospf network point-to-point            使路由正常。

interface Serial1/0

    ip address 192.168.43.4 255.255.255.0

    encapsulation frame-relay                封裝成幀中繼。

    ip ospf network non-broadcast            配置成NBMA的網絡。

    ip ospf priority 255                     使R1成爲DR。接口清閒級。

    frame-relay map ip 192.168.43.1 103 broadcast   用廣播方式發送幀中繼信息。靜態映射。（注意：對方IP和己方DLCI）

    frame-relay map ip 192.168.43.2 104 broadcast

    no frame-relay inverse-arp                 關閉自動映射。

router ospf 1

log-adjacency-changes

Network 10.43.10.0 0.0.0.255 area0

    network 3.3.3.0 0.0.0.255 area 2

    network 192.168.0 0.0.0.255 area 2

    neighbor 192.168.43.1 priority 3          在NBMA的網絡中，只能使用neighbor來指明鄰居還能夠指明鄰居的優先級。

neighbor 192.168.43.2

 

R3：

frame-relay switching                  配置成幀中繼交換機。此命令很重要。

interface Serial1/1

    no ip address

    encapsulation frame-relay              封裝成幀中繼

    clockrate 128000

    frame-relay lmi-type cisco              配置幀中繼的類型

    frame-relay intf-type dce                配置幀中繼爲DCE

    frame-relay route 103 interface Serial1/0 301    作幀中繼映射

    frame-relay route 104 interface Serial1/2 401

interface Serial1/0

    no ip address

    encapsulation frame-relay

    clockrate 128000

    frame-relay lmi-type cisco

    frame-relay intf-type dce

    frame-relay route 301 interface Serial1/1 103

interface Serial1/2

    no ip address

    encapsulation frame-relay

    clockrate 128000

    frame-relay lmi-type cisco

    frame-relay intf-type dce

    frame-relay route 401 interface Serial1/1 104

 

R1：

interface Loopback0

    ip address 1.1.1.1 255.255.255.0

    ip ospf network point-to-point

interface Serial0/1

    ip address 192.168.43.1 255.255.255.0

    encapsulation frame-relay

    ip ospf network non-broadcast

    ip ospf priority 3

    frame-relay map ip 192.168.43.4 301 broadcast

    frame-relay map ip 192.168.43.2 301 broadcast   

no frame-relay inverse-arp

router ospf 1

    log-adjacency-changes

    network 1.1.1.0 0.0.0.255 area 2

network 192.168.0 0.0.0.255 area 2

R2配置同R1

 

 

 

（2）ospf路由部分

R5

conf terminal

router ospf 1

    router-id 4.4.4.4

area 1 nssa

network 4.4.4.0 0.0.0.255 area 0

    network 10.43.10.0 0.0.0.255 area 0

    network 10.43.20.0 0.0.0.255 area 1

R6與R5配置相同，R4前面配過ospf省略

 

 

（2）ripng部分

 

R7

configure terminal

router ospf 1

router-id 6.6.6.6

area 1 nssa

network 10.43.20.0 0.0.0.255 area 1 

network 10.43.30.0 0.0.0.255 area 1

redistribute rip metric 25 subnets  //RIP->ospf

router rip

version 2

network 10.0.0.0

no auto-summary

redistribute ospf 1 metric 4 //ospf->Rip

R8

configure terminal

router rip

         Network 10.43.40.0

         Network 7.7.7.0

 

此時已經能夠從R8ping到幀中繼的R2了。

 

二．Ospfv3

1. 首先配置幀中繼

2. 配置ospfv3

3. 拓撲規劃

 

 

4. 地址規劃

四．實驗總結

  此次實驗作的十分艱難，有許多上課作過得實驗在實際作做業的時候會作不通，其實是自己沒有很好的總結上課的內容，表面上作通作會了，實際上沒有深入瞭解其中的原理和其餘的應用方法，致使拓撲稍微複雜或者變更就不會了。

  此次做業體驗最深的是幀中繼那部分，並無經過配置ip地址來實現報文的交換在此次實驗中有很深的體會。同時此次做業在查錯的時候之外的更加了解了route-id的決定原理以及手動添加變動刪除route-id的指令。

  同時仍是不太瞭解路由彙總與重發布的具體做用以及意義，只是知道大體的配置與做用，會在此次做業以後好好研究。
