Hi All,

I have 2 questions :

1. Is it possible to bind a label to an MPLS experimental bit across a 
network ? The idea is to have only 1 LSP per application (i.e. voice, exp. 
bits = 5), regardless the number of customers for MPLS VPN service? If this 
is feasible, will that raise a security issue (because no traffic 
separation).

2. What's the behavior of RSVP, when it's configured to constrain & reserved 
a 20 MB? Will it maintain 20MB LSP permanently regardless the traffic usage 
(no tear down)?

3. If it's not maintained permanently, who's controlling the actual bw 
available for the provisioning ? I meant, assuming a total 30MB bw, the 
first LSP has been configured with 25MB. Could I create another LSP with 
10MB bw ? It's sort of overbooking ;-)

3. For dynamic LSP, what's the behaviour of RSVP when it fails to find the 
required bw for its LSP ?



TIA

Aries C.
