The process of downstream site is pre-configured with by debugging logical constraint, the debugging logic.Binary tree signal shown in Figure 3
Figure, wherein, the binary tree is to be directed to MPLS (Multi-Protocol Label Switching, multiprotocol label switching)
Occur private network in L3VPN (Layer3 Virtual Private Network, VPN) and forward obstructed failure structure
, parallelogram represents location-independent logical node (abbreviation location-independent logic), and ellipse represents the (letter of analysis decision node
Claim analysis decision point), it is trapezoidal to represent positioning conclusion node (also referred to as leaf node, referred to as positioning conclusion).
In order to more fully understand the binary tree schematic diagram shown in Fig. 3, below with the basic networkings of MPLS L3VPN shown in Fig. 4
Structural representation exemplified by illustrate, MPLS L3 VPN, MPLS L3VPN are a kind of three-layer VPN technologies, and it uses BGP
(Border Gateway Protocol, Border Gateway Protocol) issues the private network of user site on service provider backbone
Route, the private network message between user site is forwarded on service provider backbone using MPLS, passes through service so as to realize
The backbone network connection of provider belongs to same VPN, the user site positioned at diverse geographic location.
Above-mentioned networking includes CE (Customer Edge, customer network edge) equipment：CE1 and CE2, PE (Provider
Edge, service provider network edge) equipment：PE1 and PE2, and P (Provider, service provider network) equipment.
Wherein, CE equipment is the user network side apparatus being directly connected with service provider network, due to " the sense of CE equipment
Know " presence less than VPN, it therefore, there is no need to support MPLS；
PE equipment is the service provider network side apparatus being connected with CE equipment, in MPLS L3VPN networks, to VPN's
All processing all occur in PE equipment；
P equipment is the backbone equipment in service provider network, is not joined directly together with CE equipment.P equipment only needs taking
User network message is transmitted to correct far-end PE equipment in business provider backbone network, it is not necessary to safeguard and handle VPN information.
When message is from one end CE equipment to other end CE equipment, local PE equipment, local PE equipment root can be reached first
Routing table corresponding to VPN is looked into according to purpose IP to be forwarded, and private network tags can be stamped after list item is found and public network label is turned
Hair, hereafter message is forwarded according to the corresponding Label Forwarding Information Base of label lookup is entered.
Obstructed failure is forwarded for occurring private network in MPLS L3VPN, its reason can substantially be divided into two major classes, Yi Leishi
Cause because VPN route study is abnormal, another kind of is due to that public network Tunnel iteration causes extremely, and public network Tunnel iteration is abnormal
Include the failure of public network tunnel building and iteration two kinds of situations of failure again.The right-hand branch of binary tree shown in Fig. 3 is used to check private
Whether net route learning is abnormal, and left-hand branch is used to check whether public network Tunnel iteration is abnormal, private network occurs in MPLS L3VPN
Obstructed failure is forwarded to can be understood as a kind of fault type, therefore the binary tree shown in Fig. 3 forwards L3VPN VPN traffics not
It is logical to be identified as location-independent logic, represented with parallelogram.Route learning between CE is identified as one-level analysis decision point, user
Ellipse represents.
Positioning conclusion in present embodiment includes two kinds, and one kind is non-code issue, i.e. network connection has rear gate chain
