Full IP tables budget routers

[js00]

Got my own AS and looking to get colo. Not looking to push more than 5Gbps what do you guys suggest on the budget side?

What does "budget" mean to you? An Arista 7280TR might do for you.

vyos on commodity hardware could manage this. Are you taking multiple tables from multiple upstreams or just one upstream? If is one upstream then you can take just a default route and use a cheap layer3 switch.

Maybe viable was hoping <$1k

Just one upstream to start with. I won't be getting any direct IP transit only what the data center itself provides. Eventually I will have equipment in two locations.

You might look at a CCR from Mikrotik then.

Interesting on the Arista. Any idea how many full tables they can hold?

That's going to depend on how well FlexRoute works with your peering relationships, but with a 32 bit image (don't use 64 bit EOS on an 8GB 7280R!) 2-3 tables from distinct neighbors is within the realm of possibility.

These platforms are cheap because 1) 10GBASE-T is going the way of the Dodo at the edge (7280SR is still a bit more spendy) and 2) they require some hoop jumping to squeeze the most out of them.

The newer edge platforms (R2/R3) are much less constrained. That said, the trick hot setup is to buy one of the 7280TRs with 8GB of system RAM and swap in a 32GB DIMM. The world is your oyster with that much RAM.

IIRC the max routes the TCAM on the first gen 7280's can store is 768K? The global table is already bigger than that, so you'd be hoping and praying the optional FIB compression can squeeze you under that, I'd assume that'd get you maybe another year of table growth if you're lucky

No, the TCAM with the internet FlexRoute policy can store up to 1.2M IPv4 prefixes on the original 7280R.

ETA: Here’s one source for that number Arista Community

ETA The Second: You’re not wrong about the lifetime of this hardware, though. There’s a reason it‘s available at the price it is.

Interesting whitepaper here: https://people.ucsc.edu/~warner/Bufs/FlexRoute-WP.pdf

Given Arista states flexroute is a separately purchased license, do you know if it's honor based or is actually required?

There's no license required on the device, no, just an EOS version from that last decade or so.
