Enums

mpls_action_t enum

The action to take for an MPLS route.

Values:

• MPLS_ACTION_NULL -
• MPLS_ACTION_PUSH -
• MPLS_ACTION_POP -
• MPLS_ACTION_SWAP -
• MPLS_ACTION_FORWARD -

mpls_ttl_mode_t enum

Whether to use the pipe or uniform TTL inheritance mode.

Values:

• MPLS_TTLMODE_NULL -
• MPLS_TTLMODE_PIPE -

  pipe” mode, do not inherit TTL from inner IP.

• MPLS_TTLMODE_UNIFORM -

  uniform” mode, inherit TTL from inner IP.

mpls_payload_type_t enum

The inner payload type. Used in a similar way to ethertype, as MPLS does not provide this in the packet.

Values:

• MPLS_PAYLOAD_TYPE_NULL -
• MPLS_PAYLOAD_TYPE_MPLS -
• MPLS_PAYLOAD_TYPE_IPV4 -
• MPLS_PAYLOAD_TYPE_IPV6 -
• MPLS_PAYLOAD_TYPE_GUESS -

class mpls_label_t

#include <mpls.h>

An MPLS label, per RFC 3032. Note: label id 0 (default value) is the explicit null label. LSRs receiving this label are expected to pop it and perform ultimate IP orwarding. MPLS label numbers are 20 bits in size, covering the range 0..1048575.

Public Type

Anonymous enum

Values:

• MIN -
• MAX = = 0xfffff -
