Re: [Ietf-hub-bangalore] IP hop by hop routing with TE

HI Dhruv

Thanks for the link it is a good introduction and relevant details on the
TE.

So when you say PCE works currently with MPLS, I would typically need a
controller (PCEP controller) with a TE database and BGP-LS
for feeding the information, right?

Which comes to the next question after PCEP controller has the TED, is
running a CSPF path a part of the PCEP role, or an application has to be
build over it?

My use case is a single IGP domain requiring light-weight TE.

Hence my choice would be a constraint based source routing mechanism. The
intelligence for which can be calculated using OSPF-TE or ISIS-TE, but the
question
remains is how do set up the transport path without MPLS.
