AW: AW: /27 the new /24

Sat Oct 3 09:04:47 UTC 2015

Hi,

yeah, of course there are newer models ... I mentioned the older ones (from the past 3-5 years). There are also Cisco routers available that are able to handle more than 1 Mio routes - of course also from Juniper.

Hi,

FYI, newer linecard models from BROCADE can hold 2 million routes. Probably others can do that now too.

Disclaimer : I'm not working for them or defending them, just setting an information straight.

My 2 cents.

>> 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.
