1.
每台路由器设置loop back口，r1和r6另外多设置两个
2.
R2 R3 R4 R5 R6做ospf
以R2为例：
ospf 1 router-id 2.2.2.2
area 0.0.0.0
network 2.2.2.0 0.0.0.255
network 23.1.1.0 0.0.0.255
3.
R1 R2 建立EBGP邻居并宣告自己
R1为例：
bgp 100
peer 12.1.1.2 as-number 200
#
network 1.1.1.0 255.255.255.0
network 2.2.2.0 255.255.255.0
network 11.11.11.0 255.255.255.0
network 12.1.1.0 255.255.255.0
peer 12.1.1.2 enable
R2:
bgp 65001
confederation id 200
peer 12.1.1.1 as-number 100
#
ipv4-family unicast
undo synchronization
network 2.2.2.0 255.255.255.0
network 6.6.6.0 255.255.255.0
network 12.1.1.0 255.255.255.0
network 66.66.66.0 255.255.255.0
注入ospf：
import-route ospf 1
4。
R2 和R3建立Ebgp邻居
R2:
bgp 65001
confederation id 200
confederation peer-as 65002
peer 12.1.1.1 as-number 100
peer 23.1.1.3 as-number 65002
#
ipv4-family unicast
undo synchronization
network 2.2.2.0 255.255.255.0
network 6.6.6.0 255.255.255.0
network 12.1.1.0 255.255.255.0
network 23.1.1.0 255.255.255.0
network 66.66.66.0 255.255.255.0
import-route ospf 1
peer 12.1.1.1 enable
peer 23.1.1.3 enable
R3:
bgp 65002
confederation id 200
confederation peer-as 65001
peer 23.1.1.2 as-number 65001
#
ipv4-family unicast
undo synchronization
peer 23.1.1.2 enable
5.
R3和R4建立IBGP 邻居
R3:
bgp 65002
confederation id 200
[Huawei-bgp]confederation peer-as 65002
[Huawei-bgp]peer 34.1.1.4 as-number 65002
后两句话不能反这写
R4:
bgp 65002
confederation id 200
peer 34.1.1.3 as-number 65002
#
ipv4-family unicast
undo synchronization
peer 34.1.1.3 enable
R3与R5建立EBGP邻居：
R3:
bgp 65002
confederation id 200
confederation peer-as 65001 65003
peer 23.1.1.2 as-number 65001
peer 34.1.1.4 as-number 65002
peer 35.1.1.5 as-number 65003
#
ipv4-family unicast
undo synchronization
peer 23.1.1.2 enable
peer 34.1.1.4 enable
peer 35.1.1.5 enable
R5:
#
bgp 65003
confederation id 200
confederation peer-as 65002
peer 35.1.1.3 as-number 65002
R5与R6建立IBGP:
R5:
bgp 65003
confederation id 200
confederation peer-as 65002
peer 35.1.1.3 as-number 65002
peer 56.1.1.6 as-number 65003
#
ipv4-family unicast
undo synchronization
peer 35.1.1.3 enable
peer 56.1.1.6 enable
R6:
bgp 65003
confederation id 200
peer 56.1.1.5 as-number 65003
此时全网通
OVER 啦啦啦啦啦
