Claim 0:
1. A protocol processing method, comprising:
carrying a leaf-transfer capability identifier in a routing in fat tree (RIFT) protocol, wherein the leaf-transfer capability identifier is configured to indicate that, a first node, that is a leaf node carrying the leaf-transfer capability identifier, supports other leaf nodes within a network to access the network through the first node, and transfers messages to other nodes;
establishing a neighbor relation between two leaf nodes carrying the leaf-transfer capability, wherein in response to all the leaf nodes in a subnet of the network supporting the leaf-transfer capability, a current link, which is an east-west link, supports the leaf-transfer capability;
flooding, by the leaf node, local prefix information of the leaf node on the link supporting the leaf-transfer capability via a prefix topology information element (Prefix TIE); and
after receiving the Prefix TIE, executing, by the leaf node, routing computation of routing in fat tree shortest path first (RIFT SPF), wherein a topology in the routing computation needs to contain the link supporting the leaf-transfer capability.
