MPLS TE and badwidth value

hello,

my question is about mpls TE.

i have the following topology

R4 - 100Mbps - R3 - 100Mbps - R2 - 155Mbps - R1

i establish an mpls TE tunnel between R4 and R1 (10.1.1.1) with a bandwidth value of 10Mbps

when i do "show mpls traffic-eng topology path tunnel0", i expect to see bandwith values decremented by 10Mbps which is reservation value.

but the output of the command is like this

R4#show mpls traffic-eng topology path tunnel0

Query Parameters:

Destination: 10.1.1.1

Bandwidth: 10000

Priorities: 1 (setup), 1 (hold)

Affinity: 0x0 (value), 0xFFFF (mask)

Query Results:

Min Bandwidth Along Path: 100000 (kbps)

Max Bandwidth Along Path: 155000 (kbps)

Hop 0: 10.1.24.4 : affinity 00000000, bandwidth 100000 (kbps) i expect ti see 90000

Hop 1: 10.1.12.2 : affinity 00000000, bandwidth 100000 (kbps) i expect ti see 90000

Hop 2: 10.1.12.1 : affinity 00000000, bandwidth 100000 (kbps) i expect ti see 90000

Hop 3: 10.1.13.1 : affinity 00000000, bandwidth 155000 (kbps) i expect ti see 145000

Hop 4: 10.1.1.1

can you help me please the understand this problem ?

thanks

Can you share your tunnel config please?

I am not sure if you are looking for something like this.

Router# show ip rsvp interface
