Switching. A new layer 2 „fabric“ for our data centre. I’m planning to
go back to a router-on-a-stick design and separate routing and
switching …

If routing is available and stable, it would not hurt, of course.
OSPF for v4 and v6, strictly IGP, definitely no uplink. Table size?
Well, how many routes can you put into a v4 /20 …? ;-) Similar
for v6, so „couple of dozen“ to „couple of hundred“. Less than
1000 routes definitely.

Turned out to be too expensive for us. 1 G/s more than enough as
edge connectivity for servers, not that much „hyperconvergence“
going on, yet. That’s why it does not pay (yet) to have higher
bandwidth at the ToR.

So I’m looking for 2-3k for a ToR switch - upper limit. We are replacing
refurbished Cisco gear that came at 600 per 48 1G ports with 2 10G
uplinks.

It’s really hard to find current manageable gear for our size ...

Thanks,
Patrick
