Hi,
Use a loose path since you are using loopbacks
mpls {
label-switched-path pe1 {
to xx.xxx.8.14 LOOSE;
}
interface fe-0/0/0.100;
}

Looks like there is some type of RSVP object/encoding that is not being
understood.

Greetings,
I'm trying to build an l3vpn between a J-series (in a lab, will be
m-series in production) and an E-series. Config seems straightforward
enough, but for some reason the two routers are not establishing
themselves as rsvp neighbors. From what I can tell, there is an LSP up
between the two routers in one direction only. The routers are connected
back-to-back via Ethernet.
This is what things look like on the J-series:

I don't have any idea what "RSVP error, subcode 14" means, and I can't
find any reference to it in the Junos or Junose docs or anywhere else
online.
I've been through the config on both routers, and I can't see any
obvious problems - although this config is fairly new to me, so I might
just be missing something. Can anyone suggest anything else to try?
