BGP in home lab

dissolved

Has anyone set BGP up in a lab environment? I have 3 spare routers to play with. They are all using an IGP in the same AS. Should I change their IGP AS to something unique, before I attempt to implement BGP?

Also, I'm guessing I'll need to incorporate iBGP as well? (use loopbacks for this?)

Any tips, recommendations appreciated. Never tried this before

BGP is used to route between AS's, so if your AS systems are not unique whats the point to run BGP in the first place??

good point

iBgp routes within your AS and eBGP between others. The point of trying would be to learn that

iBgp can also be used with eBGP for load sharing/alternate path when you are dual- homed to one ASN. We have used this before when deploying packages to remote sites that will be connecting to one ASN.

Check it out at Cisco:
