 实验:

  1. 配置接口地址及命名

[H3C]sysn r1

[r1]int g0/0

[r1-GigabitEthernet0/0]ip add 192.168.1.1 24

[H3C]sysn r2

[r2]int g0/0

[r2-GigabitEthernet0/0]ip add 192.168.1.2 24

[r2-GigabitEthernet0/0]int g0/1

[r2-GigabitEthernet0/1]ip add 192.168.2.1 24

[r2-GigabitEthernet0/1]int lo 0

[r2-LoopBack0]ip add 2.2.2.2 32

[H3C]sysn r3

[r3]int g0/0

[r3-GigabitEthernet0/0]ip add 192.168.2.2 24

[r3-GigabitEthernet0/0]int g0/1

[r3-GigabitEthernet0/1]ip add 192.168.3.1 24

[H3C]sysn rt4

[rt4]int g0/0

[rt4-GigabitEthernet0/0]ip add 192.168.3.2 24

[rt4-GigabitEthernet0/0]int g0/1

[rt4-GigabitEthernet0/1]ip add 192.168.4.1 24

[rt4-GigabitEthernet0/1]int loo 0

[rt4-LoopBack0]ip add 4.4.4.4 32

[H3C]sysn r5

[r5]int g0/0

[r5-GigabitEthernet0/0]ip add 192.168.4.2 24

2、r2 r3 r4配置ospf

 

r2:

ospf 1

area 0.0.0.0

network 192.168.2.0 0.0.0.255

r3:

ospf 1

 area 0.0.0.0

  network 192.168.2.0 0.0.0.255

  network 192.168.3.0 0.0.0.255

r4:

ospf 1

area 0.0.0.0

network 192.168.3.0 0.0.0.255

3、配置bgp部分

[r1-LoopBack0]bgp 200

[r1-bgp-default]peer 192.168.1.2 as-num 200

[r1-bgp-default]add ipv4 un

[r1-bgp-default-ipv4]peer 192.168.1.2 ena

[r2-ospf-1-area-0.0.0.0]bgp 100

[r2-bgp-default]peer 192.168.1.1 as 200

[r2-bgp-default]peer 4.4.4.4 as 100

[r2-bgp-default]peer 4.4.4.4 connect-interface LoopBack 0

[r2-bgp-default]address-family ipv4 unicast

[r2-bgp-default-ipv4]peer 192.168.1.1 enable

[r2-bgp-default-ipv4]peer 4.4.4.4 enable

[r2-bgp-default-ipv4]peer 4.4.4.4 next-hop-local

[rt4]bgp 100

[rt4-bgp-default]pe 192.168.4.2 as 300

[rt4-bgp-default]pe 2.2.2.2 as 100

[rt4-bgp-default]pe 2.2.2.2 con LoopBack 0

[rt4-bgp-default]add ipv4 un

[rt4-bgp-default-ipv4]pe 192.168.4.2 en

[rt4-bgp-default-ipv4]pe 2.2.2.2 en

[rt4-bgp-default-ipv4]pe 2.2.2.2 next-hop-local

[r5-LoopBack0]bgp 300

[r5-bgp-default]pe 192.168.4.1 as 100

[r5-bgp-default]add ipv4 un

[r5-bgp-default-ipv4]pe 192.168.4.1 en

4、在 R1 和 R5 上把业务网段宣告进 BGP 的 IPv4 地址族模式

[r1-bgp-default-ipv4]bgp 100

[r1-bgp-default]add ipv4 un

[r1-bgp-default-ipv4]netw 192.168.1.0 24

[r5-bgp-default-ipv4]bgp 300

[r5-bgp-default]add ipv4 un

[r5-bgp-default-ipv4]netw 192.168.4.0 24

5、在 R2 和 R4 上分别把 BGP 引入到 OSPF

Ospf 1

[r2-ospf-1]import-route bgp 

Ospf 1

[rt4-ospf-1]import-route bgp

 

6、r2 ospf中引入直连和 r4 ospf中引入直连

ospf 1

 import-route direct
