Abstract
The disclosed computer-implemented method may include (1) creating, at a proxy node within an IP network, a proxy group that includes a plurality of network nodes within a subnet of the IP network that are represented by a pseudo MAC address, (2) receiving a neighbor solicitation from a network node included in the proxy group, (3) identifying, within the neighbor solicitation, a link-layer address of the network node that sent the neighbor solicitation, (4) modifying the neighbor solicitation by replacing the link-layer address of the network node with the pseudo MAC address of the proxy group, and then (5) forwarding the modified neighbor solicitation to another network node included in the proxy group to facilitate completion of an NDP process in which the other network node responds to the modified neighbor solicitation with a neighbor advertisement proxied by the proxy node. Various other methods, systems, and apparatuses are also disclosed.
