It's useful if you multi home.
- Borg3 3y agoIts not necessary for multihoming. I am el-cheapo multihomed using Linux router. I use policy routing with 2 default routes (primary and secondary) and everything works like a charm. I could even try to do some ECMP but I care more about stability of ping/jitter that raw bandwidth. And you dont need to bother to ask ISP for BGP or static IPs. You just take whatever you have and slap it together.
- Hikikomori 3y agoYes, which is why I said useful. With a full table from two ISPs you know which ISP have a shorter path to a CIDR. It's also likely the same path where traffic also comes in from that CIDR.
