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 parameters router-id 192.168.3.1
set protocols bgp 10 network 10.100.100.0/24
set protocols bgp 10 network 10.100.200.0/24
# set protocols bgp 10 neighbor 192.168.1.2 ebgp-multihop 2
set protocols bgp 10 neighbor 192.168.1.2 update-source 192.168.1.1
