Lab.1 How To Configure Internal BGP Peering Mikrotik (Physical Interface)

The first BGP Lab in Mikrotik is  an Internal BGP Peering (Physical Interface)

In This lab i will use 2 router and i'm going to advertise my IP loopback when in the field i usually use the LAN Network to advertise in WAN network because BGP is an Internet Routing Protocol

Now he're Are the Topology : 

Here Are The Configuration On MikroR-1 :

[admin@MikroTik] > system identity set name=R-1
[admin@R-1] > ip address add address=10.10.10.1/24 interface=ether1
[admin@R-1] > interface bridge add name=Loopback
[admin@R-1] > ip address add address=1.1.1.1/32 interface=Loopback
[admin@R-1] > routing bgp instance set default as=100
[admin@R-1] > routing bgp peer add name=peer1 remote-address=10.10.10.2 remote-as=100
[admin@R-1] > routing bgp network add network=1.1.1.1/32
 

And Here the configuration for MikroR-2 :

[admin@MikroTik] > system identity set name=R-2
[admin@R-2] > ip address add address=10.10.10.2/24 interface=ether1
[admin@R-2] > interface bridge add name=Loopback
[admin@R-2] > ip address add address=2.2.2.2/32 interface=Loopback
[admin@R-2] > routing bgp instance set default as=100
[admin@R-2] > routing bgp peer add name=peer1 remote-address=10.10.10.2 remote-as=100
[adnin@R-2] > routing bgp network add network=2.2.2.2/32
 

And After we finish the configuration we can verified the BGP Stat by write this Command :

[admin@R-2] > routing bgp peer print status

 0 E name="peer1" instance=default remote-address=10.10.10.1 remote-as=100 tcp-md5-key=""

[admin@R-2] > ip route print detail where dst-address=1.1.1.1/32

[admin@R-2] > ip route pr
