In the previous video, we already add 1 new router to the topology. 2
Next in this video we are going to configure bgp so pc 1, pc 2, and pc 3 will able to communicate each others. Let’s just start. 3
Let’s configure on router 2 first. 4
Router bgp 2, remember that 2 is the autonomous system number of router 2, 5
Here we need to add one neighbor, which is router 3, so here neighbor 6
and then the ip address of router 3, which is 10.10.10.6, and then router 3 is in autonomous system 3, 7
so here remote-as 3. 8
Let’s also advertise the new connected network, network 10.10.10.4 mask 255.255.255.252 9
Okay now we have done configuring bgp on router 2. Next let’s configure bgp on router 3. 10
Router bgp 3, this is means that router 3 is in autonomous system 3. 11
Next let’s define the neighbor, 12
in this case router 3 will have 1 neighbor, which is router 2, so neighbor 10.10.10.5 remote-as 2 13
Okay here we can see a message that the bgp between router 2 and router 3 is up. 14
Next let’s advertise the connected network, network 10.10.10.4 mask 255.255.255.252, 15
let’s also advertise the network that connected to pc 3, so network 192.168.3.0 mask 255.255.255.0. 16
Okay now we have done configuring bgp on router 2 and router 3. 17
Let’s see the routing table on router1, 18
enable, show ip route, here we can see that now router 1 have a route to pc 3, 19
and the label is B, this is means BGP. 20
Let’s also check on router 3, do show ip route, 21
here we can see that we have route to pc 1 and pc 2, and the label is also B. 22
Okay, so now pc 1, pc 2, and pc 3 should be able to communicate each others. Let’s try, pc 1 to pc 3, 23
failed, test again, here success. 24
Let’s check from pc 2 to pc 3, okay this is also success. 25
Okay so now we have done configuring BGP on 3 router. 26
I think enough for this video 27
Thankyou for watching and see you on the next video.
