we, too, are still looking for an affordable replacement for our Cat6k switches.
While the 9k series looks interesting for data centre switching, I fear they
won't do BGP with the global routing table?

https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-9500-series-switches/data_sheet-c78-738978.html

Total number of IPv4 routes (Address Resolution Protocol [ARP] plus learned routes)
Up to 212,000 indirect + direct*
Up to 90,000 host/ARP*

If this is indeed the number of routes the system can hold, that won't do.
I wonder where those 16 GB of DRAM go with a measly 200k prefixes ...

Or am I missing something?

Since our Cat6k are not limited by switching performance but simply by
the size of the routing table, we are looking into data centre switches
for layer2/3 that hopefully consume less power and into Quagga or
similar solutions for external connectivity.

With 300 Mbit/s aggregate external traffic an amd64 based server
should easily handle that.

Kind regards
Patrick
