Careful thought should be given into whether the BGP community means "this is an anycast prefix" vs "please hot-potato to this prefix". Latency-sensitive applications may prefer hot-potato to their network even if it's not technically an anycast range, as their private bac

A Well-known BGP community will be better. You'll need to rewrite next hop or do something similar if AnyCast prefixes are learnt from a multi hop BGP feed, and it made the configuration more complicated and difficult to debug. On Wed, Mar 20, 2019, 01:48 Fredy Kuenzler wrote: > Am 19.

I wonder whether anyone has ever compiled a list of well-known Anycast prefixes. Such as 1.1.1.0/24 8.8.8.0/24 9.9.9.0/24 ... Might be useful for a routing policy such as "always route hot-potato". PS. this mail is not intended to start a flame war of hot vs. cold potato routing.
