Enumeration Type Documentation

Enumeration of the FIB table instance types.

Enumerator
IP6_FIB_TABLE_FWDING 

This table stores the routes that are used to forward traffic.

The key is the prefix, the result the adjacnecy to forward on.

IP6_FIB_TABLE_NON_FWDING 

The table that stores ALL routes learned by the DP.

Some of these routes may not be ready to install in forwarding at a given time. The key in this table is the prefix, the result is the fib_entry_t
