1. A method for processing routing table entries, comprising:
determining a first portion and a second portion in a network portion of an internet protocol version 6 (ipv6) address, and a first virtual route forwarding instance identifier corresponding to the ipv6 address, wherein the first portion is high 32 bits of the network portion and the second portion is low 32 bits of the network portion;
combining the first portion and the first virtual route forwarding instance identifier to obtain first combined information, determining a first prefix index corresponding to the first combined information, and combining the second portion and the first prefix index to obtain second combined information; and
correspondingly storing the first combined information and the first prefix index in a first routing table as routing table entry in the first routing table, and storing the second combined information in a second routing table as routing table entry in the second routing table.
