A multihomed site includes in-site network nodes, and first and second gateways configured for providing access outside of the multihomed site. The network nodes and the gateways are configured for utilizing in-site addresses having an in-site address prefix that is not advertised outside of the prescribed site. Each gateway is configured for outputting an advertisement message into the multihomed site that specifies that the gateway is a home agent for a corresponding extra-site address prefix reachable inside and outside the multihomed site. Each in-site network node includes a mobile IP module configured for acquiring extra-site addresses from each of the advertised extra-site address prefixes, and creating mobile IP tunnels with the first and second gateways, enabling the corresponding extra-site address to be reachable via the in-site address. Each node also includes a selection resource for outputting a packet on a selected mobile IP tunnel, based on preference information.
