<p>In response to a Mobile Access Router (MAR) initially attaching to a Multi-Protocol Label Switching (MPLS) domain through a first Access Router (AR) in the domain, a Mobility Anchor Point (MAP) in the MPLS domain establishes a plurality of Label Switched Paths (LSPs) for the MAR. For example, the MAP establishes an active LSP to the MAR through the AR to which the MAR has initially attached, and further establishes an inactive LSP for the MAR to each of one or more other ARs in the MPLS domain. An inactive LSP established at a given AR for a given MAR is activated when/if that MAR attaches to the AR. Correspondingly, the present invention includes method and apparatus teachings related to the MAP, ARs and the MAR, as regards establishing inactive LSPs, activating inactive LSPs, and extending an activated LSP to the MAR.</p> |
