[c-nsp] Backup methods in MPLS networks

Hi,

I am confused with the different backup methods and technologies available
and would like to just make it clear in simple terms (RSVP, LDP FRR, TE, LDP
FRR, VPN FRR, IP FRR...)

In an MPLS Core you can use MPLS TE FRR to make different LSPs(tunnels) to
protect traffic coming from PEs incase of P router or link failure, correct
?

How about LDP FRR, IP FRR, VPN FRR ? what are they used for and what are the
main diff. between each?

In the case of a CE that has one link to 2 different PEs(dual homed),
assuming one link is primary and the other is backup, which technology can
we use to steer customer VPN traffic incase the primary PE node or link
fails to the backup PE?

Thanks,
Sam
