Hi,

Flags explanations:

router—Indicates that NHRP mapping entries for a  remote router (that is accessing a network or host behind the remote  router) are marked with the router flag.

implicit—Indicates that the local node learned  about the NHRP mapping entries from the source mapping information of an  NHRP resolution request received by the local router, or from an NHRP  resolution packet being forwarded through the local router.

(no socket)—Indicates that the NHRP mapping  entries will not trigger IPsec to set up encryption because data traffic  does not need to use this tunnel. Later, if data traffic needs to use  this tunnel, the flag will change from a "(no socket)" to a "(socket)"  entry and IPsec will be triggered to set up the encryption for this  tunnel. Local and implicit NHRP mapping entries are always initially  marked as "(no socket)."
