MPLS uses a signaling protocol to exchange labels between routers.

An LSR forwards data based on the MPLS labels.

An LSP is a bi-directional tunnel that uses MPLS labels to forward data.

The data is transparently carried from end to end.

Configuring the proper values for the shared-risk link groups (SRLGs) that will define the flex-algo topology.

Configuring at least one router in the network to create and advertise the flex-algo definition.

Specifying whether the LSP paths will be computed locally or by an external path computation element (PCE).

Configuring LSPs between every pair of PE routers.

Label stack size of the encapsulated data packets

List of traffic-engineering constraint types available to choose from

Ability to associate one primary and up to two secondary paths to the same LSP

Flexibility of configuring each LSP with its own set of traffic-engineering constraints

The PCE can obtain topology and traffic-engineering information from the network using either a link-state IGP or BGP-LS.

A stateful PCE proactively monitors all the existing LSPs and triggers the necessary repairs and re-optimizations.

A stateless PCE can calculate cross-area traffic-engineering-constrained LSP paths.

A stateful PCE can allow LSPs to reserve bandwidth.

Only standard LFA is enabled on router R1; fast re-route is not enabled on router R2.

Only standard LFA is enabled on both routers R1 and R2.

Standard LFA and remote-LFA are enabled on router R1; fast re-route is not enabled on router R2.

Standard LFA and remote-LFA are enabled on router R1; standard LFA and TT-LFA are enabled on router R2.

Fast re-route is a temporary fix that becomes active for a short period of time after a local network failure.

Fast re-route typically protects the active segment of a tunnel, but under certain conditions it can protect an end-to-end multi-segment tunnel instead.

On a Nokia 7750 SR, R-LFA and TI-LFA can be enabled independently of each other.

The parameter "max-sr-frr-labels" limits the number of labels that R-LFA can add to the data packet encapsulation.
