Step 1: Configure basic information on each router
Step 2: Configure the default and static routes
Step 3: Configure BGP on both ISP routers
Step 4: View the Routing Tables
a. ISP2#show ip route
1) Is network 192.168.1.0 in the routing table of ISP2? Ya ada
2) What letter is at the left of the entry for 192.168.1.0? ‘B’
3) What does the letter mean?
4) Is network 192.168.100.0 in the routing table? Ya ada
5) Which router advertised network 192.168.1.0? 172.16.1.1
b. ISP1#show ip route
1) What network(s) did ISP1 learn from ISP2? 172.16.1.2
2) How did ISP1 learn about network 192.168.1.0? melalui 10.10.10.1
3) Will ISP1 advertise any networks to the customer router? Ya akan
c. CR#show ip route
1) Why are networks 192.168.100.0 and 192.168.200.0 not in CRs routing table? Karena semua lalu lintas dari jaringan 192.168.100.0 dan 192.168.200.0 akan menggunakan ISP1 sehingga kedua jaingan ini tidak terdapat di routing table ISP2
Step 5: Verify connectivity
Step 6: View BGP information on the ISP routers
Step 7: Reflection
Why doesn’t ISP1 advertise any networks to the customer router? Karena setiap jaringan sudah di atur menggunakan ISP yang mana, jadi tidak semua jaringan ynag ada di ISP1 di izinkan untuk menggunakan pelayanan router lainnya.
