Huawei ve Cisco router cihazları arasında BGP konfigürasyonu

Huawei ve Cisco router cihazları arasında BGP konfigürasyonu



Bu lab da cisco router ile huawei router arasında BGP konfigürasyonunun nasıl olduğunu gösterecegim.

Huawei cihazını isimlendirelim ve ip addressini oluşturalım.
<Huawei>system-view
Enter system view, return user view with Ctrl+Z.
[Huawei]sysname huawei-R1
[huawei-R1]interface GigabitEthernet 0/0/0
[huawei-R1-GigabitEthernet0/0/0]ip address 192.168.1.1 24
[huawei-R1-GigabitEthernet0/0/0]interface loopback0
[huawei-R1-LoopBack0]ip address 1.1.1.1 24
[huawei-R1-LoopBack0]interface loopback10
[huawei-R1-LoopBack10]ip address 10.10.10.10 32
Cisco cihazını isimlendirelim ve ip addressini oluşturalım.
Router>enable
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname cisco-R2
cisco-R2(config)#interface gigabitEthernet 0/0
cisco-R2(config-if)#ip address 192.168.1.2 255.255.255.0
cisco-R2(config-if)#no sh
cisco-R2(config-if)#interface loopback0
cisco-R2(config-if)#ip address 2.2.2.2 255.255.255.0
Cihazların haberleşebilmeleri için static route yazalım.
[huawei-R1]ip route-static 2.2.2.2 255.255.255.255 192.168.1.2
cisco-R2(config)#ip route 1.1.1.1 255.255.255.255 192.168.1.1
Fiziksel cihazlarımızın ip addresslerini kullanarak dogrudan BGP bağlantılarımızı kuralım.
[huawei-R1]bgp 100
[huawei-R1-bgp]peer 2.2.2.2 as-number 200
[huawei-R1-bgp]peer 2.2.2.2 ebgp-max-hop 2
[huawei-R1-bgp]peer 2.2.2.2 connect-interface LoopBack 0
[huawei-R1-bgp]network 10.10.10.10 32
cisco-R2(config)#router bgp 200
cisco-R2(config-router)#no synchronization
cisco-R2(config-router)#bgp log-neighbor-changes
cisco-R2(config-router)#network 2.2.2.2 mask 255.255.255.255
cisco-R2(config-router)#neighbor 1.1.1.1 remote-as 100
cisco-R2(config-router)#neighbor 1.1.1.1 ebgp-multihop 2
cisco-R2(config-router)#neighbor 1.1.1.1 update-source loopback 0
cisco-R2(config-router)#no auto-summary
Konfigürasyonu oluşturduktan sonra BGPyi kontrol edelim.
