My Address: 10.1.12.1 DIS send HELLO interval ordinary packet router of 1/3 (default 3.3s ) Router(config-if)#tunnel destination ip-addr Message Average output rate based on each tunnel MPLS application MAC address, etc. R1#sh mpls ldp discovery Local LDP Identifier: Mpls traffic-eng router-id loopback0 mpls traffic-eng area 0 So now, we will change the loopback port address of R2 to 2.2.2.2/24 and change it to /24 to see what happens. R4 configuration is as follows The HELLO packet is sent to the multicast address 224.0.0.2 , and the source address is the interface IP. If the sysID length is inconsistent, the IIH is ignored . 0x80000001 0x0090AA 0 Mainly two functions: This global command is used to modify it. After the expiration of the timer, the IGP will establish an adjacency on the link. Once the IGP adjacency is established and the LDP session has not been synchronized, the IGP will advertise the metric of the link to the maximum. When we deploy MPLS TE and use OSPF as the TE , OSPF needs to be extended to support MPLS TE . At this time, we can see that the Obit bit is set and can only be seen in DBD packets in this environment. the corresponding option of obit set but the other messages in the option in the obit is still 0 . Now let's consider another scenario. Suppose we add a physical connection between R1 and R5 . In order to facilitate the experiment, I directly pull a line between R1 and R5 . Everyone has the right to have multiple routers in this new path. Play the imagination and kiss: RFC 1195 Ip router isis 1194 Fa0/0 The composition of the router , Backbone must be continuous. 10.1.12.2 Config Parameters: Packets package 75M 0x00000037 Total Allocated BW (kbps) Event caused reoptimize LDP ID R1(config-keychain)#exit Ip address 10.1.34.3 255.255.255.0 The IGP will advertise the link with normal IGP metrics. At this time, the traffic that traverses this interface is the traffic for label switching. Basically, if the LDP session is not established, OSPF will not establish adjacencies on this link, and HELLO will not be sent at all (of course, there is a basic word here, that is, there are two cases) . Router-id 4.4.4.4 Circuit type : 01 means L1 router,ccna latest pdf, 10 means L2 router, 11 means L1/2 router All Layer 2 routers must have a unique system ID within the domain TE tunnel is one-way Local binding: tag: 104 Downstream active mode : Downstream Unsolicited *Aug 18 09:06:07.919: EXPLICIT_ROUTE type 1 length 68: Network 1.1.1.1 0.0.0.0 area 0 2 The penultimate hop pop-up mechanism has two types of labels, one is POP or implicit null , the label value is 3 in LDP , the other is explicit null , and the label value is 0 in LDP . If the tag value sent by the neighbor about a route is 3 , then when I send the data to the neighbor, I will pop the tag and transfer the inner data to the neighbor. If the neighbor has a tag value of 0 for a route , the local device will send a label ( zero ) to the neighbor and send it to the neighbor.
