MPLS Configuration Overview

If the order in which the LSPs are calculated is changed, the resulting set of physical paths for the LSPs also can change. Each entry in the forwarding table contains an interface-inbound label pair mapped to a set of forwarding information that is applied to all packets arriving on the specific interface with the same inbound label. The old label is replaced with a new label, and the packet is forwarded to the next hop along the Zpplications.

Meanwhile, the IGP continues its operation without modification, performing the traditional shortest-path calculation based on information contained in the router s link-state database. Required privilege level Indicates the permissions that the user must have to view or modify the statement in the router configuration.

This program and its documentation were developed at private expense, and no part of them is in the public domain. Once the packet begins to traverse the LSP, each router uses the label applications make the forwarding decision.

A separate database is maintained so that the subsequent traffic engineering computation is independent of the IGP and the IGP s link-state database. This information is provided in the text of the statement summary. Traffic engineering provides the ability to move traffic flow away from the shortest path selected by the Interior Gateway Protocol IGP and onto a potentially less congested physical path across a network. Each router maintains network link attributes and topology information in a specialized traffic engineering database TED.

You can calculate the full path for the LSP offline and statically configure the ingress applicatiobs with the full path.
