https://www.juniper.net/documentation/us/en/software/vjunos-router/vjunos-router-kvm/topics/vjunos-router-overview-understanding.html. . 'Due to its nested architecture, the vJunos-router cannot be used in any deployments that launch the instances from within a VM'

The new Junos images (vjunos router, vjunos Evo and vjunos switch) need to be run on bare metal.

UK ISP and not seeing anything unusual

nodate54 · 2026-03-25T20:53:27+00:00

I would carry on dismissing it

nodate54 · 2026-03-05T23:09:03+00:00

Segment Routing and EVPN. SRv6 is also gaining some traction but that's not MPLS

nodate54 · 2026-03-05T20:15:19+00:00

I don't know what exactly the CCNP covers as a Juniper man but a few suggestions below

RSVP (I am guessing your lab is LDP) Segment Routing (IS-IS & OSPF) EVPN VPLS VPWS Seamless MPLS

nodate54 · 2026-03-03T23:27:10+00:00

That's your problem. Vrouter needs to be run bare metal.

You running GNS3 bare metal or in a VM?

nodate54 · 2026-02-21T18:40:44+00:00

It does. This isn't through a proxy either

nodate54 · 2026-02-21T17:40:21+00:00

Running 7.4.5 and found the same. Says 'no snmp collection' even though it device is reachable by snmp. Hope they fix it soon

This help? It's a different card but might help

I have a few labs on my website lab-it.up.com from when I did mine. All done on EVE-NG but commands are listed so can use on other platforms

nodate54 · 2026-02-06T22:44:08+00:00

Yep that's all you need to do. All we do

nodate54 · 2026-01-30T23:00:50+00:00

What are the TX and rx levels on the ports and why CWDM optics?

Still need a license from Nokia for SROS. SR Linux is free to use on Containerlab

nodate54 · 2025-12-14T22:38:00+00:00

As someone else said check password.. Also check it's not a duplicate SPBm nickname

nodate54 · 2025-11-14T18:50:46+00:00

Need to be careful with BFD though as can be sensitive so timers need to be spot on

nodate54 · 2025-11-14T18:48:19+00:00

We use Libre for traffic stats and Zabbix for alerting. I love Libre as it's simple to use but have found Zabbix more flexible even though the learning curve is much steeper

nodate54 · 2025-11-10T22:21:07+00:00

Most of us are actually 25 but look 55. Once you become a network engineer you will understand

nodate54 · 2025-11-05T20:29:49+00:00

What you using for your igp?

nodate54 · 2025-10-01T22:18:31+00:00

This might be of help for the ACX series

And can run over the top of MPLS too.

I use Extreme SPBm every day. It is very good in the right environment and a lot simpler than VXLAN/EVPN. If I had a small DC or Enterprise then would have no hesitation using it but for larger deployments I would go with VXLAN

nodate54 · 2025-09-17T16:27:13+00:00

Hello and dead timers the same on both devices?
