Step S412 if the IPV6 address, then constructs the memory space of 128 of another 16 bytes, enters step S41 4;
Step S414, high 64 bit address of IP routing address information stores IPV6, simultaneously, the memory space by 128 of another 16 bytes of constructing in step S412 comes storing IP V6 to hang down 64 bit address, enters step S416; And
Step S416 for all the other 63 memory spaces, can store some necessary information according to the needs of actual reason forwarding.
Wherein, for the IPV4/IPV6 multiplexing routing table, can form the memory space of 128 of a plurality of 16 bytes by above-mentioned steps S402～step S416 according to the needs of actual routing forwarding, the size of its memory space is not limited in 16 bytes, can set arbitrarily as required.In a plurality of memory spaces, if IPV4 accounts for a memory space, then IPV6 accounts for two memory spaces, and IPV4 and IPV6 route are distinguished according to flag bit.
In step S406, the 65th of memory space is the IPV4/IPV6 flag bit, if this flag bit is 1, what then represent this memory space storage is the routing address information of IPV6, if this flag bit is 0, what then represent this memory space storage is the routing address information of IPV4, but is not limited in this.
In step S412, the IP information stores of route is in low 64 bit address.That the IPV4 route is stored is 32 purpose IP, all the other 32 according to the business of multicast, clean culture and optionally insert source IP, what the IPV6 route was stored is low 64 purpose IP addresses, high 64 purpose IP addresses are stored in another continuous memory space, and promptly the IPV6 route occupies two memory spaces.
In step S416,63 of all the other of memory space can be stored information such as source MAC, purpose MAC and purpose interface according to the needs of actual routing forwarding.
In addition, entire I PV4/IPV6 multiplexing routing table is made up of a plurality of continuous 128 memory spaces of 16 bytes.IPV4 accounts for a memory space, and IPV6 accounts for two memory spaces, and IPV4 and IPV6 route have realized the multiplexing of IPV4 and IPV6 routing table according to mark position to distinguish.
Below, with reference to Fig. 5, Fig. 6 the concrete handling process that generates IPV4 and IPV6 multiplexing routing table is described, wherein, Fig. 5 is the schematic diagram according to the IPV4 of the embodiment of the invention and IPV6 multiplexing routing table, and Fig. 6 is the particular flow sheet according to the concrete processing of the IPV4 of the embodiment of the invention and IPV6 multiplexing routing table device generation IPV4 and IPV6 multiplexing routing table.

Step S602, according to the practical application needs, the memory space of structure IPV4 and the multiplexing route of IPV6;
Step S604 becomes the identical little memory space of size with the memory allocation of IPV4 and the multiplexing route of IPV6;
Step S606, in each little memory space, low 64 storing IP V4 and IPV6 address.And, if the IPV4 route is used a memory space, DIP is stored in low 32, can select to store SIP for high 32; If two memory spaces are used in the IPV6 address, high 64 bit address of IPV6 are stored in the memory space, and low 64 bit address are stored in another memory space;
Step S608, the 65th bit-identify IPV4 and IPV6 route in each memory space.1 expression IPV6 route, 0 expression IPV4 route; And
Step S610, for the remaining space of memory space, according to the needs of actual routing forwarding, the outlet information that storage needs.
In sum, by the present invention, compared with prior art, on the basis that can keep present IPV4 routing table,, and utilize flag bit to distinguish the routing address of IPV4 and IPV6 by two memory space storing IP V4 or IPV6 routing address information.Simultaneously, in the present invention, do not increase extra cost, but effectively realized the multiplexing of IPV4 and IPV6 routing table, thereby not only saved memory space, and expanded support and storage, had very big flexibility and actual application value IPV4 and these two kinds of agreements of IPV6.
Be the preferred embodiments of the present invention only below, be not limited to the present invention, for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
