Abstract
The invention discloses a method of acquiring a device interface MRU (Maximum Receive Unit) value. The method comprises steps: a virtual link source device transmits a user datagram protocol (UDP) message whose time to live (TTL) is 1 to the self next-hop device on a virtual link, wherein the destination Internet protocol IP address of the UDP message is the virtual link neighbor IP address; and when a transmitting end receives an Internet control message protocol (ICMP) timeout error message, the unused field MRU value in the ICMP timeout error message is saved, and an UDP message whose TTL is one larger than that of the former UDP message is continuously transmitted to the self next-hop device on the virtual link. Through the scheme of the invention, the virtual link source device adopts the UDP message to acquire the MRU values of other device receiving interfaces on the virtual link, and negotiation between the MTU (Maximum Transmission Unit) value and the MRU value is realized.
Description
Technical field
The present invention relates to dynamic routing technology, espespecially a kind of acquisition equipment interface maximum reception unit (MRU,
Maximum Receive Unit) method and apparatus of value.
Background technology
Dynamic routing protocol is broadly divided into two kinds, and one is Distance Vector Routing Algorithm, and one is link shape
State routing algorithm.Distance Vector Routing Algorithm includes routing information protocol (RIP, Routing Information
Protocol), Border Gateway Protocol (BGP, Border Gateway Protocol)；Link state routing protocols
Ospf (OSPF, Open Shortest Path First), middle system is included by algorithm
System intermediate system (ISIS, Intermediate System-to-Intermediate System).In distance
In vector routing algorithm, each router safeguards a table, lists currently known self arriving in table
The optimal path of each destination, these tables by being exchanged with each other information and be continuously updated between neighbours,
Finally every router has the optimal path arriving each destination.
Owing to Distance Vector Routing Algorithm exists certain shortcoming, such as change when network topology structure
Rear Distance Vector Routing Algorithm needs the long time just can converge to state, has thus engendered link shape
State routing algorithm.In link-state routing algorithm, find by sending and receive HELLO message
Neighbours, carry out the synchronization of LSD (LSDB, Link State Database) between neighbours,
After LSDB synchronization completes, local router utilizes LSDB to build SPF (SPF, Shortest
Path First) tree, finally calculate the optimal path self arriving each destination address.
Wherein, ospf protocol both can set up neighborhood between direct-connected device, it is also possible to leap is many
Platform equipment sets up neighborhood between indirectly connected equipment, i.e. empty chain neighbours.Fig. 1 is showing of empty chain neighbours
It is intended to.As it is shown in figure 1, be empty chain neighbours between router 1 and router 3.
Before carrying out the synchronization of LSDB between neighbours, data base between transmitting terminal and receiving terminal, can be passed through
Summary (DD, Database Description) message carries out MTU (MTU, Maximum
Transmission Unit) value and maximum unit (MRU, the Maximum Receive Unit) value that receives
Consult.Specifically, Data Description (DD) packet is sent to receiving terminal by transmitting terminal；Receiving terminal receives Data Description (DD) packet,
If it is judged that the value of the interface mtu field in Data Description (DD) packet is more than the MRU value of self receiving interface,
Then process ends, does not carries out the synchronization of LSDB；If it is judged that the interface mtu in Data Description (DD) packet
The value of field less than or equal to the MRU value of self receiving interface, then returns Data Description (DD) packet to transmitting terminal,
After transmitting terminal receives Data Description (DD) packet, carry out the synchronization of LSDB.
In said process, for direct-connected device, transmitting terminal sends to receiving terminal (i.e. the neighbours of transmitting terminal)
Data Description (DD) packet in the MTU value that interface mtu field is transmitting terminal, so, transmitting terminal and receiving terminal
Between achieve MTU value and the negotiation of MRU value.For empty chain neighbours, transmitting terminal sends to receiving terminal
Data Description (DD) packet in interface mtu field be 0, so, cannot realize between transmitting terminal and receiving terminal
Negotiation between MTU value and MRU value, it is possible to cause transmitting terminal and receiving terminal carrying out
In the synchronizing process of LSDB, receiving terminal cannot the message of receiving end/sending end.Such as, in Fig. 1, if
The MTU value of the interface 1 of router 1 is more than MRU value or the router 3 of the interface 2 of router 2
The MRU value of interface 3, then in the synchronizing process carrying out LSDB, router 3 possibly cannot connect
Receive the message that router 1 sends.
