You need to color the links along the path from the Headend to the Tailend.
I have this example:
R1----R2----R3
Tunnel from R1 to R3:
tunnel mpls traffic-eng affinity 0x2 mask 0xFFFF
R1's Interface to R2:
mpls traffic-eng attribute-flags 0x2
R2's inertace to R3:
mpls traffic-eng attribute-flags 0x2
And it works :)

Subject: tunnel mpls traffic-eng affinity
Hi experts,
can somebody explain to me the Affinity value bit and mask
and how to calculate one?
i understand affinity is use for link coloring but havent been able
understand or find infor how the configured bit/mask determined.
tryin to test on dynamips and no luck
interface Tunnel88
ip unnumbered Loopback0
tunnel destination 10.10.10.11
tunnel mode mpls traffic-eng
tunnel mpls traffic-eng autoroute announce
tunnel mpls traffic-eng priority 0 0
tunnel mpls traffic-eng bandwidth 1500
tunnel mpls traffic-eng affinity 0x81 mask 0xFFFF
tunnel mpls traffic-eng path-option 1 dynamic
end
R8#sh run int f0/0.88
Building configuration...
Current configuration : 260 bytes
!
interface FastEthernet0/0.88
ip address 10.10.88.8 255.255.255.0
ip router isis
ip mpls traffic-eng tunnels
mpls traffic-eng attribute-flags 0x81
mpls ip
isis circuit-type level-1
ip rsvp bandwidth 20000
end
i added command " mpls traffic-eng attribute-flags 0x81" on the link to
tailend but but tunnel is still down
my question is
what are this affinity bit/mask and how does it work? or calculate one. pls
check bold
config t
R8(config)#INT TUN88
R8(config-if)#tunnel mpls traffic-eng affinity ?
<0x0-0xFFFFFFFF> *affinity value*
R8(config-if)#tunnel mpls traffic-eng affinity 0x81 ?
* mask mask on desired link attributes*
