Mikrotik | Lab 5. Problem with iBGP (Mesh Topolgy)

 

IMC-R1
system identity set name=IMC-R1
ip address add address=12.12.12.1/24 interface=ether1
interface bridge add name=Loopback1
ip address add address=1.1.1.1/32 interface=Loopback1 

routing bgp instance set default as=100
routing bgp peer add remote-address=12.12.12.2 remote-as=200
routing bgp network add network=1.1.1.1/32 synchronize=no

IMC-R2
system identity set name=IMC-R2
ip address add address=12.12.12.2/24 interface=ether1
ip address add address=23.23.23.2/24 interface=ether2
interface bridge add name=Loopback1
ip address add address=2.2.2.2/24 interface=Loopback1 

routing bgp instance set default as=200
routing bgp peer add remote-address=12.12.12.1 remote-as=100
routing bgp peer add remote-address=23.23.23.3 remote-as=300
routing bgp network add network=2.2.2.2/32 synchronize=no

IMC-R3
system identity set name=IMC-R3
ip address add address=23.23.23.3/24 interface=ether1
interface bridge add name=Loopback1
ip address add address=3.3.3.3/32 interface=Loopback1

routing bgp instance set default as=300
routing bgp peer add remote-address=23.23.23.2 remote-as=200
routing bgp network add network=3.3.3.3/32 synchronize=no 

VERIFIKASI:

IMC-R1#ping 3.3.3.3 src-add 1.1.1.1
routing bgp advertise print
routing bgp peer print
routing bgp network print
ip route print detail where dst-address=1.1.1.1/32

Lalu ubah topologi dengan mensamakan semua AS atau mengguanakn iBGP peering.

IMC-R1

routing bgp instance set default as=100
routing bgp peer add remote-address=12.12.12.1 remote-as=100
routing bgp network add network=2.2.2.2/32 synchronize=no

routing bgp peer add remote-address=23.23.23.3 remote-as=100

ip route add dst-add=23.23.23.0/24 gateway=12.12.12.2

IMC-R2
routing bgp instance set default as=100
routing bgp peer add remote-address=12.12.12.1 remote-as=100
routing bgp peer add remote-address=23.23.23.3 remote-as=100
routing bgp network add network=2.2.2.2/32 synchronize=no

IMC-R3
routing bgp instance set default as=100
routing bgp peer add remote-address=23.23.23.3 remote-as=100
routing bgp network add network=2.2.2.2/32 synchronize=no

routing bgp peer add remote-address=12.12.12.1 remote-as=100

ip route add dst-add=12.12.12.0/24 gateway=23.23.23.2

Lalu ping dari masing-masing router

[admin@IMC-R1] > ping 3.3.3.3  SEQ HOST                                     SIZE TTL TIME  STATUS
    0 3.3.3.3                                    56  63 5ms
    1 3.3.3.3                                    56  63 10ms
    2 3.3.3.3                                    56  63 10ms
    sent=3 received=3 packet-loss=0% min-rtt=5ms avg-rtt=8ms max-rtt=10ms

IMC-R3#ping 1.1.1.1
