I agree with Darby.... you want to use the minimum configuration needed
to answer the question. Maybe a scenario requires that BGP goes up or
down (or stays up) if a specific link goes down. This will affect where
you point your neighbor relationships. HTH

Subject: Re: BGP Neighborship using Loopback
Hmmm...
Back in class - at NMC2 this came up and I was told to
do the minimum required necessary to accomplish a
given task.
And peering with eBGP peers via the loopbacks means
adding additional commands like ebgp-multihop.
Now one of the guys who was in class with me
consistently scored 95+ percent on Caslow's CheckIT
Labs and he passed the lab the first time and made it
look easy.
So...
You may want tread carefully using extra
configuration.
I configured extra on some things and my score report
reflected things that make now think to read the
question and answer exactly what is asked.
Your money.
