Lab.2 How To Configure Internal BGP Peering Mikrotik (Loopback Interface)

In This Lab,Same like before the difference is just we're going to make 2 loopback interface
okay we're just going to use the topology before :

This Are the configuration for 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=Loopback1
[admin@R-1] > interface bridge add name=Loopback2
[admin@R-1] > ip address add address=1.1.1.1/32 interface=Loopback1
[admin@R-1] > ip address add address=11.11.11.11/32 interface=Loopback2
[admin@R-1] > ip route add dst-address=2.2.2.2/32 gateway=10.10.10.2
[admin@R-1] > routing bgp instance set default as=100 router-id=1.1.1.1
[admin@R-1] > routing bgp peer add name=peer1 remote-address=2.2.2.2 remote-as=100 update-source=Loopback1
[admin@R-1] > routing bgp network add network=11.11.11.11/32

This Are 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=Loopback1
[admin@R-2] > interface bridge add name=Loopback2
[admin@R-2] > ip address add address=2.2.2.2/32 interface=Loopback1
[admin@R-2] > ip address add address=22.22.22.22/32 interface=Loopback2
[admin@R-2] > routing bgp instance set default as=100 router-id=2.2.2.2
[admin@R-2] > routing bgp peer add name=peer1 remote-address=1.1.1.1 remote-as=100 update-source=Loopback1
[admin@R-2] > routing bgp network add network=22.22.22.22/32
[admin@R-2] > ip route add dst-address=1.1.1.1/32 gateway=10.10.10.1

After we Finish the configuration we can verified the BGP by This command :

[admin@R-2] > routing bgp peer print status
Flags: X - disabled, E - established
 0 E name="peer1" instance=default remote-address=1.1.1.1 remote-as=100 tcp-md5-key="" nexthop-choice=default

[admin@R-2] > ip route print detail where dst-address=11.11.11.11/32
