Question

哪位兄台知道关于 BGP 配置的文章？？

感谢共享，越是全面越好，，谢谢了

Answer 1

1.说明

Cisco的4908-l3的配置比较繁杂，通过IRB来实现不同桥接组之间的通讯 可以与trunk互连 但是，要对每个单独的桥接组进行封装。本实例中主要介绍在一个基于4908为中心，3500为二级交换机的园区网方案设计以及每个设备的调试过程等。着重介绍4908的配置过程 至于3500的配置请见 基本配置栏目中 关于 3500全系列配置的文章。在此，不赘述！

至于vlan分配等，通过基本配置自己体会吧 呵呵！

2.拓扑图

3.4908_Center_A 配置

User Access Verification

Password:

Password:

Center_A>en

Password:

Center_A#sho run

Building configuration...

Current configuration:

!

version 12.0

o service pad

ervice timestamps debug uptime

ervice timestamps log uptime

o service password-encryption

!

hostname Center_A

!

enable secret 5 $1$OHq9$9XvRCkMWcYtsC4glw.NYG.

enable password cisco

!

ip subnet-zero

o ip domain-lookup

ridge irb (启用IRB 有点儿象 Ip routing)

!

!

!

interface GigabitEthernet1

o ip address

o ip directed-broadcast

对物理端口不做配置，通过子接口进行封装。从下面对子接口的封装可以看出G1下面有三个bridge group (1、40、50)

!

interface GigabitEthernet1.1

encapsulation isl 1

o ip redirects

o ip directed-broadcast

ridge-group 1

!

interface GigabitEthernet1.40

encapsulation isl 40

o ip redirects

o ip directed-broadcast

ridge-group 40

!

interface GigabitEthernet1.50

encapsulation isl 50

o ip redirects

o ip directed-broadcast

ridge-group 50

!

接着进入g2的配置

interface GigabitEthernet2

o ip address

o ip directed-broadcast

!

interface GigabitEthernet2.1

encapsulation isl 1

o ip redirects

o ip directed-broadcast

ridge-group 1

!

interface GigabitEthernet2.10

encapsulation isl 10

o ip redirects

o ip directed-broadcast

ridge-group 10

!

interface GigabitEthernet2.20

encapsulation isl 20

o ip redirects

o ip directed-broadcast

ridge-group 20

!

interface GigabitEthernet2.30

encapsulation isl 30

o ip redirects

o ip directed-broadcast

ridge-group 30

!

interface GigabitEthernet2.40

encapsulation isl 40

o ip redirects

o ip directed-broadcast

ridge-group 40

!

interface GigabitEthernet2.50

encapsulation isl 50

o ip redirects

o ip directed-broadcast

ridge-group 50

!

interface GigabitEthernet3

o ip address

o ip directed-broadcast

!

interface GigabitEthernet3.1

encapsulation isl 1

o ip redirects

o ip directed-broadcast

ridge-group 1

!

interface GigabitEthernet3.150

encapsulation isl 150

o ip redirects

o ip directed-broadcast

ridge-group 150

!

interface GigabitEthernet4

o ip address

o ip directed-broadcast

!

interface GigabitEthernet4.1

encapsulation isl 1

o ip redirects

o ip directed-broadcast

ridge-group 1

!

interface GigabitEthernet4.110

encapsulation isl 110

o ip redirects

o ip directed-broadcast

ridge-group 110

!

interface GigabitEthernet4.120

encapsulation isl 120

o ip redirects

o ip directed-broadcast

ridge-group 120

!

interface GigabitEthernet4.130

encapsulation isl 130

o ip redirects

o ip directed-broadcast

ridge-group 130

!

interface GigabitEthernet4.140

encapsulation isl 140

o ip redirects

o ip directed-broadcast

ridge-group 140

!

端口G5 G6 G7用于服务器的连接

interface GigabitEthernet5

o ip address

o ip directed-broadcast

ridge-group 1

!

interface GigabitEthernet6

o ip address

o ip directed-broadcast

ridge-group 1

!

interface GigabitEthernet7

o ip address

o ip directed-broadcast

ridge-group 1

!

端口G8预留

interface GigabitEthernet8

o ip address

o ip directed-broadcast

hutdown

!

上述的br-group有点象 VLAN的划分过程

以下是对每个br-group 加上网关（可以这样理解）

interface BVI1

ip address 10.1.0.1 255.255.0.0

o ip directed-broadcast

o ip route-cache cef

!

interface BVI10

ip address 10.10.0.1 255.255.0.0

o ip directed-broadcast

o ip route-cache cef

!

interface BVI20

ip address 10.20.0.1 255.255.0.0

o ip directed-broadcast

o ip route-cache cef

!

interface BVI30

ip address 10.30.0.1 255.255.0.0

o ip directed-broadcast

o ip route-cache cef

!

interface BVI40

ip address 10.40.0.1 255.255.0.0

o ip directed-broadcast

o ip route-cache cef

!

interface BVI50

ip address 10.50.0.1 255.255.0.0

o ip directed-broadcast

o ip route-cache cef

!

interface BVI110

ip address 10.110.0.1 255.255.0.0

o ip directed-broadcast

o ip route-cache cef

!

interface BVI120

ip address 10.120.0.1 255.255.0.0

o ip directed-broadcast

o ip route-cache cef

!

interface BVI130

ip address 10.130.0.1 255.255.0.0

o ip directed-broadcast

o ip route-cache cef

!

interface BVI140

ip address 10.140.0.1 255.255.0.0

o ip directed-broadcast

o ip route-cache cef

!

interface BVI150

ip address 10.150.0.1 255.255.0.0

o ip directed-broadcast

o ip route-cache cef

!

ip classless

!

在每个br-group中指定可路由的协议

ridge 1 protocol ieee

ridge 1 route ip

ridge 10 protocol ieee

ridge 10 route ip

ridge 20 protocol ieee

ridge 20 route ip

ridge 30 protocol ieee

ridge 30 route ip

ridge 40 protocol ieee

ridge 40 route ip

ridge 50 protocol ieee

ridge 50 route ip

ridge 110 protocol ieee

ridge 110 route ip

ridge 120 protocol ieee

ridge 120 route ip

ridge 130 protocol ieee

ridge 130 route ip

ridge 140 protocol ieee

ridge 140 route ip

ridge 150 protocol ieee

ridge 150 route ip

!

line con 0

assword cisco

transport input none

line aux 0

assword cisco

line vty 0 4

assword cisco

login

!

end

就可以了

Center_A#

不过不能通过4908实现 VTP server client的配置！

只能通过透明传输 不过 对于二级的堆叠组可以局域实现 server client的配置

4.Center_B 配置
