Hi folks,

Anyone tried running crafted bypass LSPs? 
I can't get mine working in the lab on 15.1F6 and have no idea why,  

Example: 
To primary LSP tail-end IP:
set protocols rsvp interface ge-0/0/0.0 link-protection bypass test-to-pe1
to 10.0.0.21 
set protocols rsvp interface ge-0/0/0.0 link-protection bypass test-to-pe1
bandwidth 1m
set protocols rsvp interface ge-0/0/0.0 link-protection bypass test-to-pe1
path 10.0.0.2 loose
set protocols rsvp interface ge-0/0/0.0 link-protection bypass test-to-pe1
path 10.0.0.14 loose
set protocols rsvp interface ge-0/0/0.0 link-protection bypass test-to-pe1
path 10.0.0.20 loose
To node protecting MP IP:
set protocols rsvp interface ge-0/0/0.0 link-protection bypass test-to-cr2
to 10.0.0.13
set protocols rsvp interface ge-0/0/0.0 link-protection bypass test-to-cr2
bandwidth 0
set protocols rsvp interface ge-0/0/0.0 link-protection bypass test-to-cr2
path 10.0.0.2 loose
set protocols rsvp interface ge-0/0/0.0 link-protection bypass test-to-cr2
path 10.0.0.8 loose

Even with BW=0, 
The LSPs or rsvp interface extensive output keeps on complaining there's no
sufficient BW (but for the automatic bypass LSP) -however I want my primary
LSPs to use these crafted bypasses instead of the automatically created
ones. 
(the bypass test-to-cr2 is practically the same thing as what would have
bene created automatically)
show rsvp session name BE_POP1_TO_PE1POP4_RED_0 extensive
Type: Protection down
      1 Oct 16 09:10:05 No suitable bypass with sufficient bandwidth[23
times]
show rsvp interface ge-0/0/0.0 extensive
Protection: On, Bypass: 0, LSP: 1, Protected LSP: 0, Unprotected LSP: 1
     10 Oct 15 19:41:24 No suitable bypass with sufficient bandwidth
Bypass->10.1.0.40->10.1.0.17[4 times]

LSP is configured with node/link protection:  
set protocols mpls label-switched-path BE_POP1_TO_PE1POP4_RED_0
node-link-protection
