AW: /27 the new /24

Sat Oct 3 08:33:24 UTC 2015

As mentioned before: even the new SUP2T from Cisco is limited to 1Mio routes ...

There are MANY other vendors with the same limitations: Juniper, Brocade, etc

And the solt equipment is not the 99USD trash from the super market at the corner ...

Which routers? DIR-300 with OpenWRT/Quagga? :)

I think all above-the-trash level routers supports >1M routes, isn't it?

> I was in a discussion the other day and several Tier2 providers were talking about the idea of adjusting their BGP filters to accept prefixes smaller than a /24.  A few were saying they thought about going down to as small as a /27.  This was mainly due to more networks coming online and not having even a /24 of IPv4 space.  The first argument is against this is the potential bloat the global routing table could have.  Many folks have worked hard for years to summarize and such. others were saying they would do a /26 or bigger.
