1. A method, comprising:
receiving, by the device, a common loopback Internet protocol (IP) address assigned to a group of network nodes of a network, physical interface IP addresses, each associated with one of the group of network nodes, and metrics, each associated with one of the group of network nodes, wherein the common loopback IP address is assigned to the group of network nodes, the group of network nodes are associated with tracking area codes (TACs), and each of the TACs identifies a corresponding tracking area;
storing, by the device, the received common loopback IP address, the received physical interface IP addresses, and the received metrics in a route table, wherein the received physical interface IP addresses and the received metrics correspond to the received common loopback IP address in the route table;
receiving, by the device and from user equipment, a request to connect to the network;
determining, by the device, among the group of network nodes, a particular network node to which to forward a communication session of the user equipment, based on the received common loopback IP address;
selecting, by the device, the particular network node based on the request and based on the metrics which correspond to the common loopback IP address and are stored in the route table; and
routing, by the device, the communication session of the user equipment to the particular network node, wherein the particular network node enables the user equipment to connect to the network.
