We didn’t find a more interesting topic than BGP to start with.
In this topic we will be covering some BGP features as Route Reflectors, Multihoming, Transit-AS, influencing route selection using Local Preference and MED, and Route Aggregation.
Topology:
Tasks:
1- Configure an IGP to achieve full reachability inside AS 200.
2- Configure RR to act as a Route Reflector for all router inside AS 200.
3- Use Loopback interfaces for all IBGP speaking routers.
4- Configure EBGP between [R1, ISP1] [R2, ISP2].
5- Ensure EBGP reachability to all IBGP speaking routers without advertising external links subnets.
6- Ensure that ISP1 is the upstream for AS 200 and ISP2 is the downstream for AS 200.
7- Aggregate the 30.1.0.0/24 & 30.2.0.0/24 address spaces to be 30.0.0.0/16 when exiting AS 300.
Verifications:
1- To verify full EBGP reachability, ping loopback interfaces of IBGP routers inside AS200.
2- To verify that ISP1 is the upstream for AS200, traceroute any loopback interface inside AS101 from AS200.
3- To verify that ISP2 is the downstream for AS200, traceroute any loopback interface inside AS200 from AS101.
3- To verify that Transit-AS, ping from AS300 to AS101 and vice versa.
Solution:
You will find below the detailed physical connections and the routers configuration files:

Good start Abdullah, in spite of I preferred the mulltihomed topology and using the AS-PATH prepending…
this lab is pretty cool and contains a lot of staff you need to know about BGP….
GO TEAM SCOUTS 😉
Part 2 will be even more interesting .. wait 4 it 🙂
Good work my friends .. keep it up
Abdullah, we are waiting for the documented solution/configuration for the above lab 😛
Configuration files are finally here, EnJoY !!
Thanks Abdullah for the updated configuration files, I will check it practical and feed you back…
The lab is really great; covers many features for applying BGP in AS.
However, i think it would be more practical if you use in your lab one of the Link-state protocols instead of EIGRP, in case you want it to be like a documentation for BGP lab implementation.
Keep it up Guys 🙂
Well done, a very good useful lab, covering more topics in BGP and waiting
more labs.
Go on brothers 🙂
I c u Guys provide a great Work , Thank you Assisting your Bros
