Title: Getting ready for multigig
Post by: Reformed on March 18, 2022, 12:12:47 AM
Greets everyone. I was wondering if people had suggestions for equipment to use to get our home ready to make the most of >1 Gbps services?

WiFi 6e looks to be a big expense. I was thinking about switches with at least 2 SFP+ ports. Most equipment in the home is wireless or GigE.

As part of this I've also started taking maintaining and managing the network more seriously. It now has LibreNMS (https://www.librenms.org) along with ntopng (https://www.ntop.org) fed by nProbe running on it.

With the amount of Internet of gack devices running on it from Amazon's finest to CCTV and meaty desktops to the pair of Pis providing DNS and DHCP it seemed beyond time to work out what is actually connected to what.

Its generally a bad time for it, the silicon shortage is still in force.

Had a busy few days. Network is 10G but has a couple of single points of failure. A secondary route to build a dual spine is on tomorrow's list.

After that leaf switches. Awaiting stock.

I'm totally going to forget to enable RSTP and loop things senseless.

Logical diagram attached. Nice and simple given there are 3 routers. I like throwing hardware at things.

Thank you. I always like a nice diagram.

A stupid question. I don’t understand this stuff at all. What do you do about IP addresses in your own ASes?  Do you have PI space?
Title: Re: Getting ready for multigig

I'm not advertising them anywhere else and they are from the private range. 64512-65534 are the private AS numbers.

EDIT: Each of them advertise a default gateway, withdrawn if their ISP link goes. One of them advertises a routed /29. Two of them advertise a couple of other subnets.

The router that'll take the YouFibre link, the main one, will be routing out to the Internet only. Flows to the networks connected to the other routers will see the first packet from the home LAN go to the primary and it'll respond with an ICMP redirect pointing them to the appropriate router.

Okay the switch I needed arrives over the weekend. New WiFi 6e access point in.

May I ask what the WAP is? (Did you mention it earlier?)

I wasn't aware any had come to market that weren't an absolutely absurd price.

I want WiFi 6e but at more than double the price of WiFi 6, its not worth it, especially with Apple making the odd choice of only putting WiFi 6 in the Macbook M1 Pro.

My gaming laptop is 6e capable in theory as I put an AX210 in there, but not sure how the antennas will handle it nor do I use that machine much any more.

Okay. In part due to the quarantine boredom work complete. The 2 rooms with wired equipment and low needs have 10G to the core. The core is a 4 switch 10G throughout mesh. The primary Internet connection has 2 10G links into LAN, the backup router 10G and 2.5G.

Most of this is active:standby to keep traffic flows sensible alongside there being no need for >10, however a move to 20G is doable - there are spare switch ports available to bond and 20G between the core switch pairs.

With some port space to upgrade to move capacity to 20G when required with some bonding.

A bunch of rearranging and recabling was done overnight while there was no-one to infect. £500 spent on a bargainous switch and importing special fibre cabling from Spain and Texas.

At least I achieved something while the nasty has been doing its work.

Oh no, sorry to hear you’ve been quarantined. As you said, at least you got something done.

The curious has to ask for more details, please. The switch make/model and what is special about the Spanish & Texan fibre cables?

The cable is white and depending on which 1mm thick and very flexible or 3mm thick and armoured to resist cats. It's bizarrely difficult to get white single mode fibre with connectors already attached.

I purchased a Xyzel XGS1210-12 which in turn freed up a 4 x SFP+ switch.

The rest of the cost was SFPs and a couple of rack mounted trays to hold switches and an ONU.

Agreed. If only your colour scheme was yellow.  ;)

Thank you. Curiosity has now abated.

I’m definitely liking that switch.

Must say standard SMF bothers me, I wish I'd bought one with an outer sheath around the two inner ones, so it looks more like a normal cable, as I kinda worry its too flexible and exposed to being damaged.  Granted, the fibre itself is insanely thin inside those sheaths.  I'd like a cable I can't physically bend too tightly as I'm scared to cable manage the fibre.

Still, no point replacing it now just in case it gets damaged, as that defeats the point really.  IF it gets damaged I should then get something more robust.

I was able to yank it through the hole my other cables come through without issue, that sheathing is so slippery its the easiest cable run I've ever done.

Good reason I pay the extra for BiDi transceivers. Twice the price but rides on half the fibre.

Bend insensitive stuff is a thing though. This is the stuff I get from the USA.

It's a lot less fragile than you give it credit for.

Ah, InvisiLight fibre. I have read good things about that brand.

It's very simple, like me, and just works. More than adequate for what I need it to do.
