[j-nsp] SRX PPPoE issue on JunOS 12.1X44-D35.5

[Benjamin Collet]

Hi,

I am trying to upgrade an SRX210H from the previous recommended version
(11.4R11.4) to the current one (12.1X44-D35.5), however with the exact
same configuration the PPP session doesn't come up. I rolled back to the
previous recommended version and it works back perfectly.

It appears that the Link Control Protocol phase is stuck in `Creq-sent`
state, and then times out (see
https://paste.oxynux.org/zwq8hb-3053?raw).

I didn't find anything relevant in the release notes but I might have
missed something.

Here are the relevant parts of my configuration:

Would anyone have a clue or could help me towards the right direction,
before I dig more and start some intrusive wire-listening?

Cheers,
Ben
