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=toISP2 remote-address=192.168.3.2 remote-as=20
add name=toISP3 remote-address=192.168.1.2 remote-as=30
# jika ingin redistribute default route ke client yang spesifik
# add name=toISP2 remote-address=192.168.3.2 remote-as=20 default-originate=if-installed
# add name=toISP3 remote-address=192.168.1.2 remote-as=30 default-originate=if-installed
#
# advertize routing
#
/routing bgp network
add network=10.100.100.0/24 synchronize=no
add network=10.100.200.0/24 synchronize=no

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
#
# advertize routing
#
/routing bgp network
add network=10.10.10.0/24 synchronize=no
add network=10.10.20.0/24 synchronize=no

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: 

#set our AS number
/routing bgp instance
  set default as=30
  redistribute-connected=yes
  redistribute-ospf=yes
#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
#
# advertize network
#
/routing bgp network
add network=10.1.1.0/24 synchronize=no
add network=10.1.2.0/24 synchronize=no

OSPF

ISP3 

# /routing ospf instance add name=default 
/routing ospf instance set name=default router-id=10.1.1.1 numbers=0 redistribute-bgp=yes
/routing ospf instance enable numbers=0
/routing ospf network add network=10.1.1.0/24 area=backbone 
/routing ospf network add network=10.1.2.0/24 area=backbone


R4 

# /routing ospf instance add name=default 
/routing ospf instance set name=default router-id=10.1.1.2 numbers=0
/routing ospf instance enable numbers=0
/routing ospf network add network=10.1.1.0/24 area=backbone 
/routing ospf network add network=172.16.1.0/24 area=backbone 
/routing ospf network add network=172.16.10.0/24 area=backbone 
/routing ospf network add network=172.16.20.0/24 area=backbone

R5 

# /routing ospf instance add name=default 
/routing ospf instance set name=default router-id=10.1.2.2 numbers=0
/routing ospf instance enable numbers=0
/routing ospf network add network=10.1.2.0/24 area=backbone
