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 protocols bgp 10 neighbor 192.168.1.2 ebgp-multihop '2'
set protocols bgp 10 neighbor 192.168.1.2 remote-as '20'
set protocols bgp 10 neighbor 192.168.1.2 update-source '192.168.1.1'
set protocols bgp 10 neighbor 192.168.3.2 ebgp-multihop '2'
set protocols bgp 10 neighbor 192.168.3.2 remote-as '30'
set protocols bgp 10 neighbor 192.168.3.2 update-source '192.168.1.1'
set protocols bgp 10 network '10.100.100.0/24'
set protocols bgp 10 network '10.100.200.0/24'
set protocols bgp 10 parameters router-id '192.168.1.1'

ISP2 

set protocols bgp 20 neighbor 192.168.3.1 ebgp-multihop '2'
set protocols bgp 20 neighbor 192.168.3.1 remote-as '10'
set protocols bgp 20 neighbor 192.168.3.1 update-source '192.168.2.1'
set protocols bgp 20 neighbor 192.168.2.2 ebgp-multihop '2'
set protocols bgp 20 neighbor 192.168.2.2 remote-as '30'
set protocols bgp 20 neighbor 192.168.2.2 update-source '192.168.2.1'
set protocols bgp 20 network '10.10.10.0/24'
set protocols bgp 20 network '10.10.20.0/24'
set protocols bgp 20 parameters router-id '192.168.2.1'

ISP3 

set protocols bgp 30 neighbor 192.168.1.1 ebgp-multihop '2'
set protocols bgp 30 neighbor 192.168.1.1 remote-as '10'
set protocols bgp 30 neighbor 192.168.1.1 update-source '192.168.1.2'
set protocols bgp 30 neighbor 192.168.2.1 ebgp-multihop '2'
set protocols bgp 30 neighbor 192.168.2.1 remote-as '20'
set protocols bgp 30 neighbor 192.168.2.1 update-source '192.168.1.2'
