An international toy store company needs your help. They use BGP to exchange routing information between their sites but everytime one of their IBGP routers fails they have connectivity issues. Let’s see if you can help them out!
- All IP addresses have been preconfigured for you.
- Configure EBGP between AS 1 and AS 2.
- Configure EBGP between AS 2 and AS 3.
- Configure router Pegasus to advertise network 220.127.116.11 /24 in BGP.
- Configure router Phoenix to advertise network 18.104.22.168 /24 in BGP.
- Configure router Pegasus so it does no longer advertise network 22.214.171.124 /24 when network 126.96.36.199 /24 is no longer reachable.

On router pegasus im seeing that both networks are 192.168.12.0 in your diagram
Nice work absolutely wonderful just there is little typo in topology ip address link between Pagasus and Pixie is 192.168.23.x not .12 rest is all good
I like your name selection thoughts
Just fixed it, thanks for your comment!
Thanks….Can you add a video for Performance Routing (PfR) in GNS3..
Will do for sure, it’s still on my to-do list but it’s one of those topics that i’m not too excited about =)
Nice and wonderful it works nice, i am learining unknown things from this vault. Thanks for your amazing blog..
Thank you for your kind words 🙂
I have just had a look at this video and have a following questin.
You created conditional map which withdraws lo0 188.8.131.52 when neighbour relationship between pagesus and phenox is manually shutdown. My question is as follows.
Would bgp not automatically withdraw 184.108.40.206 from its BGP routing table and stop advertising any routes leared from Phenox wheh the neighbour relationship between the two goes down?
I look forward to your feedback.
It will no longer advertise network 220.127.116.11 /24 anymore once this neighbor adjacency is down but it will still advertise 18.104.22.168 /24.
The key to this lab is that we don’t want to advertise 22.214.171.124 /24 anymore once 126.96.36.199 /24 disappears from the routing table of Pegasus.
Keep in mind that network 188.8.131.52 /24 is on the loopback from router Pegasus so it will be advertised to router Pixie.
Thank you so much for your struggle and giving support other people , i really appreciate you work MR ReneMolenaar.
I have simple question ,how can i ping pixie from phoneix ?
i will be look forward for you appreciated reply.
Thank you again.
ok, how can PIXIE see Loopback 184.108.40.206, if fa0/0 Pegasus is shutdown. IT is true
Pls follow the link to solve above scenario
