Re: [j-nsp] what do do with bug reports
--- Begin Message --- For 100% sure you should open a JTAC Case, like P3, as you have a current workaround. JTAC should then reproduce your issue, at which time they will create a PR for Engg to work on. PR will be scheduled to be fixed in some future release. JTAC should be able to provide that feedback to you once Engg has updated the PR. Do NOT let JTAC close your case, until you get at least this far. Also make sure that JTAC ties your Case to the PR. Customer logged (CL) PRs have priority over Internal logged (IL) PRs. You should also now be able to view PR via external PR tool. You can then keep case open until you actually get a fix, or allow JTAC to close the case while you wait for the fix. Case would be 100% in monitor during this time. Case closure time is a top metric for TAC. If you do nothing, Juniper will also do nothing, as no one outside of you knows about this. If situation is known by Juniper (PR already open) your case can be tied to that PR, or new PR can be marked as a duplicate of older PR.

Hi, File a JTAC problem report, either yourself via a Juniper Partner (where you should have support for your devices). Rgds.

Re: [j-nsp] what do do with bug reports
Hi Baldur, You should not give up and just report the bug. JTAC may ask you to disable feature that is causing an impact, but in the meantime they will work on resolving it. Mind that it might take some time to replicate the problem, prepare the fix and implement it in the next official software release.

[j-nsp] what do do with bug reports
Hello What am I supposed to do with glaring bugs? Are Juniper interested in knowing those or don't they care? In this case I found out that 19.1 behaves badly if you set [system services subscriber-management overrides interfaces family inet receive-gratuitous-arp]. The setting is supposed to enable updating the ARP table when receiving gratuitous ARP from clients. Instead it makes the router reply to those ARP packets, which causes the clients to reject the address.
