TYPE                     LINK ID                 LINK DATA
 
----------------------------------------------------------------------------
 
1 - Router link          neighbor's router ID    interface number
 
(Point-to-Point)
 
1 - Router link             address prefix for      length (in bits) of prefix
 
(Connect-to-Stub)                subnetwork
 
3 - Summary link         -                       length (in bits) of prefix
 
(IP network)
