Re: diffrnece b/w Te-metric & LSP metric

Correct Brian.

Thanks for your input...

But I am working in junos environment only,,,and In junos Te-metric & LSP
metric are two different things.

My understanding is that,, we will configure te-metric lower then the IGP
cost on every router and configure the IGP metric at the higest value.
This is done so that traffic should always take MPLS path rather than IGP
path.

Second parameter is LSP metric ,,,which can be configured mannualy or
dynamic inherted from IGP. best practice is to static configure LSP metric
on each router if you are using RSVP full mesh.This is required to have
stablity inn the n/w ,,change in IGP will not affect LSP,,,as LSP metric is
staticaly configured.

But I am still confused on how these parameters came into picture in LSP
formation.
