hello

i find in cisco web site how to configure RSVP but not how RSVP works.

i have some questions:

-1- must RSVP be configured in all routers that separate source to destination? or just the 2 extremities?

-2-can you explain more the RSVP neighbor concept?

-3-how to know if the network accepted the rsvp request or rejected it? and how the router reacts if the network can't provide the RSVP request?

-4- what makes RSVP different from other features like CAR, GTS, service-plocy...

thanks
