Task #1124
Updated by Junxiao Shi over 10 years ago
Define a **prefix registration protocol** that supports adding and removing one nexthop on a FIB entry.
Functionality is similar to `prefixreg` and `selfreg` and `unreg` actions of [CCNx Registration Protocol](http://www.ccnx.org/releases/latest/doc/technical/Registration.html).
An equivalent of `CCN_FORW_CHILD_INHERIT` should be supported.
Each nexthop is associated with a cost. The cost represents a preference of this nexthop. A nexthop with lower cost is prefered to a nexthop with higher cost.
