Typedef Documentation

◆ fib_bfd_state_t

typedef enum fib_bfd_state_t_ fib_bfd_state_t

Distillation of the BFD session states into a go/no-go for using the associated tracked FIB entry.

◆ fib_entry_delegate_t

typedef struct fib_entry_delegate_t_ fib_entry_delegate_t

A Delagate is a means to implmenet the Delagation design pattern; the extension of an objects functionality through the composition of, and delgation to, other objects.

These 'other' objects are delegates. Delagates are thus attached to other FIB objects to extend their functionality.

◆ fib_entry_delegate_track_t

typedef struct fib_entry_delegate_track_t_ fib_entry_delegate_track_t

State for FIB entry tracking.

◆ fib_entry_delegate_type_t

typedef enum fib_entry_delegate_type_t_ fib_entry_delegate_type_t

Delegate types.

Enumeration Type Documentation

◆ fib_bfd_state_t_

Distillation of the BFD session states into a go/no-go for using the associated tracked FIB entry.

◆ fib_entry_delegate_type_t_

enum fib_entry_delegate_type_t_

Delegate types.

Enumerator
FIB_ENTRY_DELEGATE_CHAIN_UNICAST_IP4	Forwarding chain types: for the vast majority of FIB entries only one chain is required - the one that forwards traffic matching the fib_entry_t's fib_prefix_t. For those fib_entry_t that are a resolution target for other fib_entry_t's they will also need the chain to provide forwarding for those children. We store these additional chains in delegates to save memory in the common case.
