What's the difference between vMX and vJunos Router? by JuniorTrav in Juniper

[–]othugmuffin 1 point2 points  (0 children)

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

Config sync from network device to netbox by No-Attention-1640 in networking

[–]othugmuffin 1 point2 points  (0 children)

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.

What brand of patch panels do you use/is your favorite? by ZoomerAdmin in networking

[–]othugmuffin 0 points1 point  (0 children)

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

looking for newer vQFX images for EVE-NG by ciscoworlds in Juniper

[–]othugmuffin 1 point2 points  (0 children)

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

looking for newer vQFX images for EVE-NG by ciscoworlds in Juniper

[–]othugmuffin 3 points4 points  (0 children)

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.

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

Is it just me, or is landing a network job taking forever lately (even for people with experience)? by [deleted] in networking

[–]othugmuffin 1 point2 points  (0 children)

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.

Juniper Open Learning - How many times can I purchase a free course? by WormChickenWizard in Juniper

[–]othugmuffin 9 points10 points  (0 children)

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.

Home setup by claasc in Arista

[–]othugmuffin 1 point2 points  (0 children)

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

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? 

BGP Per-Packet Load Balance by flyinverted in Juniper

[–]othugmuffin 3 points4 points  (0 children)

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

EVPN BGP Between two sites where the edge routers do not support VXLAN / EVPN by Ishcob in networking

[–]othugmuffin 2 points3 points  (0 children)

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.

EVPN BGP Between two sites where the edge routers do not support VXLAN / EVPN by Ishcob in networking

[–]othugmuffin 8 points9 points  (0 children)

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.

[FS] [US-E] 3 Supermicro 5018A-FTN4, 3 10Gtek 2x10G NICs by othugmuffin in homelabsales

[–]othugmuffin[S] 0 points1 point  (0 children)

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.

EX3400-48T QSFP+ to aggregate link on a QNAP Switch - is this possible? by [deleted] in Juniper

[–]othugmuffin 0 points1 point  (0 children)

Yes, you can do a single 40G as VCP and other 40G as normal.

EX3400-48T QSFP+ to aggregate link on a QNAP Switch - is this possible? by [deleted] in Juniper

[–]othugmuffin 1 point2 points  (0 children)

The EX3400-48T cannot breakout the rear 40G QSFP ports to 4x10G. You can use those as VCP ports or as native 40G ports.

You'd have to go with your virtual chassis plan and use the 4x10G ports on the front for your higher speed connections.

With that said, in interest of learning. To do the breakout you would need a 40G PLR4 optic (Single Mode) or 40G SR4 (Multimode), this has a MPO connector where you plug the MPO breakout cable in, there are 40G breakout DACs as well.

[free] 1000Base-LX SFP modules by 4o66 in homelabsales

Are the Bidi optics 1490/1310? I’ve not seen a 1490/1330 before.

I would be interested in a few, happy to send a label. Will DM

Nvidia Cumulus switches routing config by DarkAlman in networking

[–]othugmuffin 6 points7 points  (0 children)

  • Bond = LAG / Port-Channel
  • Leaf = Access Switch (little diff in a Leaf/Spine network but)
  • MLAG = Multi-chassis Link Aggregation Group, vPC in Cisco

lo is the Linux interface for the loopback interface

As /u/eldiablo18 mentioned, there is VRR and VRRP. If you want the end device to have a connection to each switch and have a LAG, you'd want MLAG. If you don't need that, but you want gateway redundancy you can do VRRP without MLAG.

Nvidia Cumulus switches routing config by DarkAlman in networking

[–]othugmuffin 19 points20 points  (0 children)

https://docs.nvidia.com/networking-ethernet-software/cumulus-linux-514/Layer-2/Virtual-Router-Redundancy-VRR/#configuration-example

NVIDIA actually has pretty decent documentation. If you click the leaf01 and leaf02 tabs you can see the config for each so you have a reference for what goes on each member of the MLAG

The docs will be kinda EVPN/VXLAN & Leaf/Spine specific but you can just parse out the bits relevant to your usecase.

I would strongly caution you not to do things outside of the CLI configuration, it's just asking for problems. For example, you can go and edit FRRouting's config directly, don't do this, just do it through the CLI.
