Ada tiga (3) ISP
ISP1:
IP 192.168.1.1/24 menuju ISP3 IP 192.168.3.1/24 menuju ISP2 AS 10 IP 10.100.100.0/24 IP 10.100.200.0/24
ISP2
IP 192.168.2.1/24 - menuju ISP3 IP 192.168.3.2/24 - menuju ISP1 AS 20 IP 10.10.10.0/24 IP 10.10.20.0/24
ISP3 (kita)
IP 192.168.1.2/24 - menuju ISP1 IP 192.168.2.2/24 - menuju ISP2 AS 30 IP 10.1.1.0/24 IP 10.1.2.0/24
Setup connection
ISP1
/ip address add interface=ether1 address=192.168.1.1/24 /ip address add interface=ether2 address=192.168.3.1/24 /ip address add interface=ether3 address=10.100.100.1/24 /ip address add interface=ether4 address=10.100.200.1/24
ISP2
/ip address add interface=ether1 address=192.168.2.1/24 /ip address add interface=ether2 address=192.168.3.2/24 /ip address add interface=ether3 address=10.10.10.1/24 /ip address add interface=ether4 address=10.10.20.1/24
ISP3
/ip address add interface=ether1 address=192.168.1.2/24 /ip address add interface=ether2 address=192.168.2.2/24 /ip address add interface=ether3 address=10.1.1.1/24 /ip address add interface=ether4 address=10.1.2.1/24
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
#set our AS number /routing bgp instance set default as=10 #add BGP peers /routing bgp peer add name=toISP3 remote-address=192.168.1.2 remote-as=30 add name=toISP2 remote-address=192.168.3.2 remote-as=20
ISP2
#set our AS number /routing bgp instance set default as=20 #add BGP peers /routing bgp peer add name=toISP1 remote-address=192.168.3.1 remote-as=10 add name=toISP3 remote-address=192.168.2.2 remote-as=30
ISP3
#set our AS number /routing bgp instance set default as=30 #add BGP peers /routing bgp peer add name=toISP1 remote-address=192.168.1.1 remote-as=10 add name=toISP2 remote-address=192.168.2.1 remote-as=20
Network Advertisements and Routing Filters
Start advertise our network & filter out all other unnecessary advertisement.
ISP1:
# advertise out network /routing bgp network add network=10.100.100.0/24 synchronize=no add network=10.100.200.0/24 synchronize=no
ISP2:
# advertise out network /routing bgp network add network=10.10.10.0/24 synchronize=no add network=10.10.20.0/24 synchronize=no
ISP3:
# advertise out network /routing bgp network add network=10.1.1.0/24 synchronize=no add network=10.1.2.0/24 synchronize=no
