Abstract
The present disclosure provides a method and apparatus for failure detection and a PE device, and in particular, relates to the field of communication technology. The present disclosure is applied to the first PE device in EVPN. The first PE device is connected to the second PE device through the SRv6 PW tunnel. The method includes: generating an SRv6 packet, wherein a first indicator included in the SRv6 packets indicates that an inner packet of the SRv6 packet is a BFD packet; sending the SRv6 packet to the second PE device, so that when the second PE device is a tail node, the second PE device establishes a BFD session with a head node based on the BFD packet, and when the head node detects that the PW tunnel between the head node and the tail node fails through the BFD session, the head node switches a service flow to a backup tunnel; or, when the second PE device is a splice device, the second PE device transparently transmits the BFD packet to the tail node, so that the BFD session is established between the head node and the tail node, and when the head node detects that the PW tunnel between the head node and the tail node fails through the BFD session, the head node switch…
