BGP Peering
Consider that IP connectivity between ISPs edge routers and Our Core router is already set up and working properly. So we can start to establish BGP peering to both ISPs.
ISP1:
enable
configure terminal
router bgp 10
bgp router-id 192.168.1.1
network 10.100.100.0/24
network 10.100.200.0/24
neighbor 192.168.3.2 remote-as 20
neighbor 192.168.1.2 remote-as 30
end
ISP2:
enable
configure terminal
router bgp 20
bgp router-id 192.168.2.1
network 10.10.10.0/24
network 10.10.20.0/24
neighbor 192.168.3.1 remote-as 10
neighbor 192.168.2.2 remote-as 30
end
Main / Backup Link Setup di ISP3
Lakukan
- accept network kita sendiri
- drop semua tabel IP lainnya, karena kita tidak mau menjadi transit provider
- BGP AS prepend - menaikan AS path ke salah satu ISP (disini ISP1)
ISP3:
enable
configure terminal
router bgp 30
bgp router-id 192.168.1.2
no synchronization
bgp log-neighbor-changes
network 10.1.1.0/24
network 10.1.2.0/24
neighbor 192.168.1.1 remote-as 10
neighbor 192.168.2.1 remote-as 20
redistribute ospf 3 metric 100
end
OSPF
ISP3
enable configure terminal ! ! area 0 = backbone router ospf 3 network 10.1.1.0/24 area 0.0.0.0 network 10.1.2.0/24 area 0.0.0.0 end
R4
enable configure terminal ! ! area 0 = backbone router ospf 4 network 10.1.1.0/24 area 0.0.0.0 network 172.16.1.0/24 area 0.0.0.0 network 172.16.10.0/24 area 0.0.0.0 network 172.16.20.0/24 area 0.0.0.0 end
R5
enable configure terminal ! ! area 0 = backbone router ospf 5 network 10.1.2.0/24 area 0.0.0.0 network 172.16.1.0/24 area 0.0.0.0 network 172.16.100.0/24 area 0.0.0.0 network 172.16.200.0/24 area 0.0.0.0 end
Cek
! perhatikan AS 30 di tambahkan 5x ke routing ke arah AS 10 ! show ip bgp
show ip route show ip bgp 10.100.1000.0/24 show ip bgp neighbors 192.168.2.2 advertised-routes show ip bgp neighbor 192.168.1.1 routes show bgp ipv4 unicast neighbors show bgp ipv4 unicast summary
