Hello,
I am trying to understand how IBGP and EBGP behave in JunOS and I find that the official documentation is in no way enough to understand what is going on.
What surprised me was that everything I advertised into IBGP was being re-advertised to my neighbor ASes through EBGP. I find that not very useful and I'm trying to understand if there are any other gotchas.
Can anyone here confirm that the following is correct?
Default JunOS IBGP behavior:
export routes that the localhost learned through EBGP
import routes that remote hosts learned through EBGP
Default JunOS EBGP behavior:
export routes that the localhost learned through EBGP or IBGP (!)
import routes that the remote hosts learned through EBGP or IBGP
