Is this a place to ask or get help on a Juniper router issue?
I am trying to learn and then pass Juniper certification(s) and bout a J2320 router with a serial card. Even though it appears serial connections are no longer used and people have said I am wasting my time trying to make a serial connection between the Juniper serial card and another Juniper J2320 serial card (I really want to make it to a Cisco 1821 router serial card), I have been trying to to find out how to successfully do so.
If not here, can you suggest where to get help?
Juniper won't help me at all - must contact a 'partner' and of course, since I am just a one person learning at home, am of not enough $$$$ to get any 'partner' interested in helping me.

Im aware that the MX80's Flash can get worn out over time.
Ive had to replace a few MX80s flashes with a compatible 3rd party USB/Flash to get them back up and running. (yes, voids warranty field-stripping an MX80 to get at the 2 flash modules in the rear area of the motherboard) -- but it worked.
Field strip. Swap the flashes, Boot from USB installer, install JunOS, make a basic fxp0 config, load latest JunOS, push config back from RANCID, and the boxes are back in production and happy.

Possibly-missing-something-obvious question: are there any less-involved
alternatives to link coloring to preclude RSVP from signaling LSPs through
specific nodes?
I've got some traffic occasionally wandering off where it shouldn't be --
mostly due to bypass LSPs landing on some "temporary" links -- and in this
case, it'd be handy to just say "this box is never allowed to be a P
router" and call it solved.

Just a little comment in case someone else needs QinQ on small SRXs:
Layer 3 termination of QinQ does work on SRX, even if VPLS does
not. That is unlikely to help the original poster, but others might find
it useful.
I.e. you can do this kind of thing on a plain SRX300:
ge-0/0/5 {
flexible-vlan-tagging;
encapsulation flexible-ethernet-services;
unit 20 {
vlan-tags outer 0x8100.300 inner 0x8100.20;
family inet {
address 198.18.1.2/30;
}
}
}

I know of a few methods for steering traffic in MPLS-TE/RSVP-TE, I've done
this in IOS-XR, but not in Junos at this point... but i found this link that
might help in Junos... https://www.inetzero.com/in-control-with-rsvp/
One way is to change the te-metric on that P router that you don't want lsp
to pass through...but that might be too global as it would seem to affect
all TE LSP's passing through there.
set protocols isis interface ge-0/0/1 level 1 te-metric 100
clear lsp to re-signal
Make sure to do that on the opposite side te tunnel as you usually need to
setup one in each direction as a te tunnel is unidirectional... however, i
just learned of corouted-bidirectional, seems interesting
https://www.juniper.net/documentation/en_US/junos/topics/topic-map/basic-lsp
-configurtion.html#id-configuring-corouted-bidirectional-lsps
again, this seems to be a nice and easy way to exclude a P router in cisco
ios-xr from the te head-end, i don't know of the junos equivelent for this

In this case, it's OSPF, so overload is just max metric. The path metric
already exceeds any other through the network under ordinary conditions,
which is why it's only a problem on occasion, and with bypass LSPs in
particular.
IGP metric isn't enough when "best path" is the same answer as "only
available path", and it looks like switch-away-lsps goes too far in the
opposite direction.

Hi! Experts
I need some 10GE LR optics and found 2 options in Juniper : SFPP-10GE-LR-IT
and SFPP-10GE-LR.
>From Juniper Hardware Compatibility Tool I can't find a difference
except SFPP-10GE-LR-IT has a widely operating temperature range
and SFPP-10GE-LR-IT price is lower. So it seems SFPP-10GE-LR-IT is a more
attractive choice.
Could you pls shed some lights on this and thanks for your help.

Have a look on the second tab of the hardware compatibility tool - the supported platforms.
-IT is only supported on ACX710, and that?s the only one the ACX710 supports (i.e. it doesn?t support SFPP-10GE-LR).
Why? Not sure.
If I had to guess, it?s because the operating temp range of the ACXs are wider than other boxes on the low end and that matches the -IT model.. Though I note that the older ACX platforms (500, 1k, 2k, 4k at least) can work at -40c as well, and at least some of those can take SFPP-10G-LR.
Maybe whoever the ACX710 was made for (a few things about the 710 suggest to me at least that they were made for a specific customer) is really strict about SFP specs.
They are *much* cheaper list price, huh? Like, 1/8th. Odd.
There seems to be -IT variants of a few SFP+s.
