Summary:Examples disclosed herein relate to a method comprising receiving a bidirectional forwarding detection (BFD) packet originating from a first network device, wherein the first linked network device and a second linked network device are part of a link aggregation group running a BFD session. The method may include transmitting, from the first linked network device, a BFD synchronization packet to the second linked network device and receiving, at the second linked network device, the BFD synchronization packet, wherein a time-to-live (TTL) value of the BFD synchronization packet is lower than a BFD TTL supported by the BFD session. The method may also include determining that the BFD synchronization packet is a BFD single-hop packet coming from a VLANs using the active forwarding mode and determining not to discard the BFD synchronization packet.
