Abstract
In an example, a spine node may receive a first internet protocol (IP) packet sent by the first leaf through a first interface. The spine node may obtain a forwarding entry for forwarding the first IP packet; wherein, the forwarding entry comprises a fast bypass tag field and an egress interface field instructing a second interface for forwarding the first IP packet. The spine node may determine a third interface from a fast recovery leaf node group in response to determining that the second interface fails and the value of the fast bypass tag field is a first value, wherein the third interface is different from the second interface and is connected to a second leaf node. The spine node may send a second IP packet, which includes a destination media access control (MAC) address and the first IP packet, to the second leaf node through the third interface.
