◆ ip6_fib_show_ctx_t

◆ ip6_fib_walk_ctx_t

Context when walking the IPv6 table.

Since all VRFs are in the same hash table, we need to filter only those we need as we walk

Get or create an IPv6 fib.

Get or create an IPv4 fib with the provided table ID.

Parameters
imip4_main pointer.
table_idWhen set to ~0, an arbitrary and unused fib ID is picked and can be retrieved with ret->table_id. Otherwise, the fib ID to be used to retrieve or create the desired fib.
Returns
A pointer to the retrieved or created fib.
