Typedef Documentation

typedef struct ip6_fib_show_ctx_t_ ip6_fib_show_ctx_t

typedef struct ip6_fib_walk_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

table_id

)

Get or create an IPv6 fib.

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

Parameters

im	ip4_main pointer.
table_id	When 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.
