Type definitions in mpls

namespace eos

Enums

enum mpls_action_t

The action to take for an MPLS route.

Values:

MPLS_ACTION_NULL

MPLS_ACTION_PUSH

MPLS_ACTION_POP

MPLS_ACTION_SWAP

MPLS_ACTION_FORWARD

enum mpls_ttl_mode_t

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.

enum mpls_payload_type_t

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 Types

enum [anonymous]

Values:

MIN

MAX = 0xfffff

INVALID = 0x100000
