I am just curious if every ISPs will accept a /24 subnet for BGP advertisement. If not, is there a way to find out what they do accept and/or who doesn't accept this?
Secondly, we have a primary ISP that is advertise a /16 and on the secondary ISP, we advertised a /24 subnet (that is included in the /16 of the primary ISP) to test speed and throughout..etc to avoid having to bring out the primary circuit.
We're seeing some different throughput when testing with speedtest.net and when changing the server to a local city, we're getting latency error so not sure about this.
The /24 is a local subnet on the second ISP router and I Just advertised this under the BGP statement and we have a default route out with a next hop of our second ISP. The second ISP has a static route for this /24 to us and a default route out to the internet.
Not sure what might be causing some latency errors when changing the speedtest to some local servers. It seems to be fine if we change the server to Seattle, Washington for example and I'm located in SF.
