Subject: lt interface bandwidth
Hello
Thank you GRZEGORZ DACKA for your reply.
I saw, what was my issue.
Switching tunnel-services bandwidth at chassis level from 1g to 10g or more, changes the numbering of lt interfaces, which caused my first setup that worked with 1g to no longer work when I changed the bandwidth to 10g. So I adapted according lt numbering interfaces and it works.
But I stil have some question.
What is the impact of fpc throughput when using lt interfaces ?
Is there any limitation when using lt- interfaces on MX204 ?
If you have any suggestion, please fill free to share.
Thank you again.

Hello
First do You check Your port config https://apps.juniper.net/home/port-checker/index.html ?
If Yes remember when You use lt interface also use bandwitch so if you have like example 4 x 100G Qsfp use so that the issue
Pls show if is possible config of both logical system configuration regarding lt interface

What about just dropping the «bandwidth <whatever>» part of both lines, that is actually not needed at all ?

Hello
We have Juniper MX204 (version 20.4R3-S3.4) as PEs in our backbone, we want to terminate l2circuit to l3vpn on PE, then, we used logical tunnel interface.
What I'm trying to acheve is this :
https://www.juniper.net/documentation/us/en/software/junos/vpn-l3/topics/topic-map/l3-vpns-connecting-to-layer2-circuits.html
Our setup is working only when tunnel-services bandwidth is set at 1Gigabit/s, as below :
set chassis fpc 0 pic 0 tunnel-services bandwidth 1g
set chassis fpc 0 pic 1 tunnel-services bandwidth 1g
When we setup bandwidth to 10g, lt- interfaces are not working (even, they are not displayed when trying "sh interface terse | match lt-)
set chassis fpc 0 pic 0 tunnel-services bandwidth 10g
set chassis fpc 0 pic 1 tunnel-services bandwidth 10g
I have some questions:
1- Do logical tunnel interfaces on juniper MX204 are limited to 1g as bandwidth ?
2- Did you know why logical tunnel interfaces set à 10Gigabit/s as bandwidth are not working ?
2- How many logical tunnel subinterfaces MX204 can support ?
3- Is there any lt- interface limitations in terms of QoS for example ?
4- Can you share some documents ?
Thank you for your replies.
