there are better things than a full restart....

"write" followed by a "reload warm" is way more faster and you dont have to
deal with the 3+ years old systemd bugs....

"write erase" also should work, then re-pasting the good parts...

just one thing, don't trust linux in the rare builds, they're way too old....
:(

thanks,

cs

Frederic, we did systemct stop/start of freertr. And it helped to some extent.

Current status is:

* Cleanup up ISIS config from two VRFs. It is only present in eantc-bgp-ct.
* and ISIS is stable now. Best effort ping over LU is passing.
* RSVP-TE LSPs between PE1->ASBR1 are no-cspf, strict hop EROs.
* RSVP-TE from ASBR1->PE1 using eantc-bgp-ct as signaling instance, but
using eantc-bgp-ct-gold/bronze for forwarding.
* Only problem is: *CT advertised labels are not installed to P4 forwarding*

the following labels advertised ASBR1->ASBR2 are not getting installed to P4.

core#show mpls forwarding | include 661923

661923 eantc-bgp-ct-bronze:4tunnel3100.1.2.3630

core#show mpls forwarding | include 164692

164692 eantc-bgp-ct-gold:4tunnel2100.1.1.3630

core#show p4lang p4 done-mpls | include 661923

core#show p4lang p4 done-mpls | include 164692

Can you or Csaba help with debugging and fixing this?

Fyi: Latest free-rtr config is saved at: /rtr-sw-20230320-1800-PDT.txt, also
attached to this mail.

And the pings to verify the streams are (from PE2):

Best-effort: *root@Juniper-34-MX204_5> ping 100.2.0.36 source 100.2.0.34 rapid count 2 *
Gold SLA:***root@Juniper-34-MX204_5> ping 100.3.0.36 source 100.3.0.34 rapid count 2 *
**Bronze SLA:***root@Juniper-34-MX204_5> ping 100.5.0.36 source 100.5.0.34 rapid count 2***
Ping us if you need anything while debugging this.

Thanks

Does this happen everytime you issue clear p4lang p4 ?
Or is it an isolated case ?

In that case I suggest first to issue restart freertr via systemd.

Hi Frederic,

P4 stopped working after we did a clear p4lang p4 . Need your help to
fix up the dataplane.

Thanks,
