This application provides a communication method and apparatus applied to a first network device. The method includes: obtaining at least one first address, each first address being the address of a second network device and each second network device being a network device that has performed capability negotiation with the first network device; and, based on each first address, performing dynamic capability negotiation for a first service with the corresponding second network device; wherein the at least one first address is an address of the first network device under the enabled dynamic peering function.

A conditional high availability peering among all members of an all-active NGFW cluster is established. Data paths are monitored via a dynamic routing protocol capable of conditional advertisement, such as BGP, to detect network isolation failures. Peering can be temporarily suspended with the remote NGFWs by withdrawing the local IP address used for high availability peering to the remote NGFWs, responsive to the detected data path failure. Responsive to detecting a cure of the failed data path using said dynamic routing protocol, the high availability peering to remote NGFW nodes is automatically restored by resuming advertisement of the local peering IP address of the NGFW, wherein the high availability peering is reactivated for all remote NGFW nodes.

Methods are provided for ensuring that a service node selects a local leaf node to reach remote destinations by leveraging reverse metric to inform the active service node of the topology of the leaf nodes. The methods involve obtaining connection information about a service node. The connection information indicates whether the service node is locally connected or connected via a virtual private network (VPN) tunnel. The methods further involve generating a reverse metric signaling based on the connection information. The reverse metric signaling includes a different metric value for the service node when the service node is locally connected than when the service node is connected via the VPN tunnel. The methods further involve providing the reverse metric signaling to the service node to cause the service node to select an intermediate network device from among a plurality of intermediate network devices to forward data traffic to a destination.
