MPLS RSVP-TE & LDP inside Cisco routers.

Hi,

I have a question please about MPLS RSVP-TE & LDP inside Cisco routers. I read in an IEEE article "Designing Multiprotocol Label Switching Networks" by Jeremy Lawrence, from Cisco. There is a footnote:

"It is, in principle, possible to run an MPLS network using the Resource

Reservation Protocl plus extensions, but without the use of the Label

Distribution Protocol. However, it is not clear whether any MPLS

implementation supports this."

From which I deduce that Cisco requires LDP to always exist with RSVP-TE inside Cisco MPLS routers. Is this true?, and if yes can you tell me please why RSVP-TE should be tied with LDP? Is this to enhance the network bandwidth usage or what?

thanks,

Hatem Eyada

Re: MPLS RSVP-TE & LDP inside Cisco routers.

Since there has been no response to your post, it appears to be either too complex or too rare an issue for other forum members to assist you. If you don't get a suitable response to your post, you may wish to review our resources at the online Technical Assistance Center (http://www.cisco.com/tac) or speak with a TAC engineer. You can open a TAC case online at http://www.cisco.com/tac/caseopen

If anyone else in the forum has some advice, please reply to this thread.

Thank you for posting.
