mpls-te on isis with Juniper

Working on understanding mpls-te

diagram: https://imgur.com/a/uHfqG5M

I want to use the red path as primary and my blue as backup.

Why has the blue path come up but red path stays down?

relevant show commands

show commands on r1: https://pastebin.com/03AipPrv

show commands r2,r4,r5,r7: https://pastebin.com/FTtawXUw

**diagram**

Each router has a loopback of itself i.e. r1 = 1.1.1.1, r2 = 2.2.2.2 etc

running isis everywhere. Yellow router = area 1 and green router = area 2

every device is configured as L1/L2

enabled rsvp on all links

**troubleshooting**

checked colors of all links - ok

checked rsvp enabled on all links - ok

shut down xe-0/0/0 on R4 and shutdown xe-0/0/0 and xe-0/0/1 on R1 to force traffic to go from R1 to R4 > R5 > R7 -- ok (i.e. traceroute works)
