Abstract
A first map request message is sent from a source network device to a mapping network device to determine a destination network device associated with a destination endpoint device and a security association between the source network device and the destination network device. A first response message is received at the source network device that includes data indicating a mapping between the destination network device and the destination endpoint device and data indicating a security association between the source network device and the destination network device. The data is stored at the source network device. A second map request message is sent from the source network device to the mapping network device to update the data indicative of the mapping or the security association. A second response message is received at the source network device from the mapping network device.
