OSPF of LSA aging time for the 3600s , refresh interval Consider in detail the details of the adjacency relationship establishment process: The load of the routing processor is low in large areas Router isis 968 Maximum reservable bandwidth : 9375000 Number of Priority : 8 Interface fast0/0 Then R1 will use the IGP of Metric , and ignore R2 on the configuration of the physical interface adminnitration-weight , so after the entry into force of the above command, go R1 view on the tunnel 's path weight , it turned into a 3 . The above command will add or subtract z from the original cost of the route ( the range of z is -10 to 10 ) LDP certification 1144 Of course, when deploying, we strongly recommend that the same tunnel should have the same priority and priority.

The LSP of R3\R3 is similar, and will not be described here. Take a look at the LSP of this pseudonode : Lsp-refresh-inverval to modify. First of all, all routers run routing protocols, and the entire network is interoperable. Next, LDP is activated on the interface of the router, and an LDP adjacency relationship is formed between the two routers . OSI PDU Interface eth0/1 Priority 3 : 9375000 Attribute tag and affinity attribute basic configuration IS ( layer 0 routing ), then the router will look up the destination address and forward the packet along the best path. The configuration of R3 is as follows: Reservable Bandwidth[1]: L1 Overload-bit Interface Loopback0 The subnet point of attachments is the point at which the subnet service is provided, which is equivalent to the second layer address of the corresponding Layer 3 address ( NET or NSAP ). usually Mpls ldp neighbor 3.3.3.3 targeted ldp Describes all LSP information in the LSP database .

A value of 0 indicates a length of 6B , a value of 255 indicates a length of 0 , and other system ID fields may have a length of 1-8 bytes. i L1 The first 6 is the setup priority and the second 6 is the hold priority .

It is very inefficient to rebuild the LDP session. We can protect the session and implement LDP session between the two directly connected LSRs . After the protection, a destination-based LDP session is established between the two LSRs , that is, the target LDP session . When the direct link between the two LSRs is DOWN , as long as there exists between the two LSRs .
