Claim:
1. A method comprising: receiving, by a first router within a data center, a route advertisement for a border gateway protocol (BGP) labeled unicast (LU) route that specifies a destination address of a second router within the data center that originated the BGP-LU route, a Multiprotocol Label Switching (MPLS) label and next hop data for reaching the second router, wherein the BGP-LU route further specifies a community attribute identifying a region within the data center in which the second router is located; responsive to determining that the region identified by the community attribute specified by the BGP-LU route matches a region in which the first router is located, allocating a label with the first router and modifying the route advertisement by rewriting the label specified within the route advertisement with the label allocated by the first router and rewriting the next hop data within the route advertisement to a network address assigned to the first router; and re-advertising, with the first router, the modified route advertisement within the data center.
