Abstract

A bit index explicit replication (BIER) operations, administration, and maintenance (OAM) detection method includes a bit forwarding ingress router (BFIR) obtaining a detection request packet based on a first BIER OAM packet, and sending the detection request packet to at least one bit forwarding egress router BFER. The detection request packet includes a first packet and a first packet header. The first packet is a packet obtained by encapsulating the first BIER OAM packet. The first packet header includes a bit string, and the bit string indicates the at least one bit forwarding egress router BFER that is to be measured.

Claims20

Dependent claims

A method, comprising:

obtaining, based on a first bit index explicit replication (BIER) operations, administration, and maintenance (OAM) packet, a detection request packet, wherein the detection request packet comprises a first packet, a first packet header, and a second packet header, wherein the first packet is based on encapsulation of the first BIER OAM packet, wherein the first packet header comprises a bit string, wherein the bit string indicates a bit forwarding egress router (BFER) that is to be measured, wherein the first packet comprises a first destination address that is a valid address that can be identified by the BFER, wherein the second packet header comprises a second destination address that is a next hop for BIER forwarding, wherein the first destination address is configured to not be updated, and wherein the second destination address is configured to be continually updated;
and
sending the detection request packet to the BFER.

An apparatus, comprising:

a memory configured to store instructions;
and
one or more processors coupled to the memory and configured to execute the instructions to:
obtain, based on a first bit index explicit replication (BIER) operations, administration, and maintenance (OAM) packet, a detection request packet, wherein the detection request packet comprises a first packet, a first packet header, and a second packet header, wherein the first packet is based on encapsulation of the first BIER OAM packet, wherein the first packet header comprises a bit string, wherein the bit string indicates a bit forwarding egress router (BFER) that is to be measured, wherein the first packet comprises a first destination address that is a valid address that can be identified by the BFER, wherein the second packet header comprises a second destination address that is a next hop for BIER forwarding, wherein the first destination address is configured to not be updated, and wherein the second destination address is configured to be continually updated;
and
send the detection request packet to the BFER.
