iBGP vs. eBGP Review
iBGP and eBGP are the same protocol; just different rules.
Rules are counter-intuitive -
- eBGP advertises everything to everyone by default. OOPS - don’t be MAE-Clueless.
- iBGP does NOT advertise “3rd-party routes” to other iBGP peers. Why?
- No way to do loop detection with iBGP, so this solves it.
