I've never really understood why the internet at large uses BGP instead of more advanced protocols like OSPF.

I've never really understood why the internet at large uses BGP instead of more advanced protocols like OSPF.
- NoZebra120vClip 3y agoApples and Oranges: OSPF is an interior gateway protocol for routing within an autonomous system, and it's not designed for exterior routing, which is how eBGP holds the fabric of the Internet together.
- mmcallister 3y agoOSPF is an interior routing protocol that transmits link state. Link state based routing algorithms aren't a good fit for interconnected networks
- inopinatus 3y agoEvery now and then a major ISP accidentally redistributes a million border routes into their IGP with catastrophic results, as a reminder for the rest of us that OSPF et al aren’t designed to handle that many LSAs.
