Hi All,


1. What options do I have for label distibution and signaling, if what I 
need are COS (bandwidth and TOS/diffserv mapping to MPLS experiment bits) 
and TE (explicit hop-by-hop LSP, rather than IGP) ? I notice the books I 
read only mention LDP/TDP, but other vendor typically write LDP or RSVP.
2. Why other type of TE seems not popular (i.e. OSPF TE, etc.)? In Cisco 
books I have, they don't even mention about RSVP TE.
3. Based on your experience with some different vendors, will turning on 
LDP/RSVP at FE subinterfaces (both at egress PE1 and ingress P) causes 
disruption on the live traffic at the interface, which has been running 
without sub-interfaces ?


TIA


Aries C
