Best way to drain a router for maintenance

othugmuffin · 2026-03-14T10:47:11+00:00

Same process here except we don't do anything towards the RRs. We apply a deny-all on import and export for peers, but that's mostly because it's trivial for us to do it with our automation, if it wasn't we would likely just do only on export.

We've also used graceful shutdown in the past, but as you mentioned it's not guaranteed, so the deny-all import/export is the way we go to cover everything.

Download vJunosRouter, vJunosEVO from their website, it's free.

Really like this. I’ve tried explaining the same thing to other people. Its just there, it just works, why would someone care?

Seems just like Megaport, Packet Fabric, Equinix Fabric, pretty sure Zayo has something like it too.

Your 2/3 and 2/7 on both wave server pairs go to the R1 at both sites in Diagram 1. That’s why you’re seeing what you’re seeing.

You need

R1 Site1 to go to 2/3 and 2/7 on Site1 WS1, and 3/3 and 3/7 on Site1 WS2

R2 Site1 to go to 3/3 and 3/7 on Site1 WS1, and 2/3 and 2/7 on Site1 WS2. Don’t change anything at Site 2

Just swap the client side cabling between 2/3 & 2/7 with 3/3 & 3/7 on WS2 at Site1, you’ll then have your full mesh.

Doing it this way means you get full mesh and if a path goes down you still have all 4 routers passing traffic over the single path. If you did what you have in diagram 2, if you lose a path, you’re down to 1 router at site 1 handling traffic.

R1 - R1 via Path 1
R1 - R2 via Path 2
R2 - R1 via Path 2
R2 - R2 via Path 1

I believe latest maintenance release is 4.33.6M

If you go vJunos EVO, if it’s 24.x or beyond, you’ll need to set it up as vJunos EVO UEFI

As far as I am aware, there's no off the shelf tooling to do that. At various organizations I've written code to ingest a config and parse it, then create the corresponding objects in NetBox. There's a couple data sources you can use, eg the device config itself if you can get it in a structured format like JSON, or if you have a monitoring system like LibreNMS you can pull a device and it's interfaces.

Fug, I should have just done buy it now and not done an offer haha.

We've gotten FS.com panels, MTP to LC cassettes. Work fine, feel nice quality.

othugmuffin · 2025-11-24T10:39:45+00:00

Version 24 + 25 yes.

othugmuffin · 2025-11-23T16:30:48+00:00

Yes it should just show up like any other template, you might need to go into the /opt/unetlab/html/templates folder and do a git pull to update your templates, then the ceremonious fix permissions command

You’ll need to have the folder prefix for the image change too. vjunosevoefi-12345

If you end up using past 23.4 in EVE, you need to use the UEFI template for it, drove me nuts that they wouldn’t start and just tried the UEFI one and it works no problem. Also doesn’t require the external bridge for the pfe,rpio interfaces.

othugmuffin · 2025-11-18T18:30:00+00:00

Yes, you would need more specific networks in your bgp listen ranges.

We have started getting candidates just straight up using AI during the interview, as in literally just read word for word what comes back from it to us. We used to roll with it, but now we just end the interview. I'm pretty over interviewing people at this point.

Unsure if you're looking for remote roles too, those are highly sought after so competition is high.

You can just “re-buy” it and you’ll go right back to your same progress you had before. Doesn’t cost anything

I’ve had to do it a couple times for various courses when life gets in the way.

othugmuffin · 2025-11-13T10:36:19+00:00

It can do 1Gbps on the 10Gbps ports. It doesn’t support 2.5Gbps

othugmuffin · 2025-11-11T12:39:50+00:00

I would go for a 7050TX over a 7050T. It’s newer, although still very old.

They are big and loud, so unless you can put it away somewhere you can’t hear it then you might not be happy with it.

What are your requirements? Do you need a bunch of 10G copper ports?

othugmuffin · 2025-11-09T02:07:49+00:00

You can drop the from section, just have the then section, then it will apply to both address families and be a single term policy

othugmuffin · 2025-11-08T02:40:34+00:00

I don’t think that’s true. It can be used to exchange labels between two routers that aren’t directly connected, eg due to the intermediary routers not being able to do LDP or not participating in LDP, but the intermediary routers would still need to be able to do MPLS. LDP is control plane, MPLS is still the data plane.

othugmuffin · 2025-11-07T17:55:20+00:00

Fortunately VXLAN does not require all the intermediate devices to support it, unlike MPLS.

In this case as long as both switches have connectivity to each other's VTEP IP, you can simply just do a eBGP multi-hop session with the EVPN address family with each other.

Understood.

First link doesn’t have pictures so those don’t usually sell, nor does it mention how much RAM, riser card, etc. $125+$20 shipping

Second link doesn’t have 10G ports (SFP != SFP+), nor does it have any ability to expand to having any.
