Let's make a small summary below: Interface eth 0/1 Pay attention to the distinction between autoroute and here . The autoroute feature is not activated in our configuration above . Autoroute feature and autoroute *Aug 18 11:26:02.546: SRM : used to control the delivery of LSPs to adjacent routers during the update process. Next, add a PVC between R2 and R3 : Interface fas1/0 Ip router isis Network 10.1.34.4 0.0.0.0 area 0 *Aug 18 11:26:02.546: 5 !!

This brings great convenience to our network maintenance and troubleshooting. Net 49. 0001 .0000.0000.0001.00 ! There are three types of PDUs : the IS-the IS of ES-IS and CLNP ! Configuration command !!tunnel establishment and retention priority Used to confirm and request link status information Network 2.2.2.2 0.0.0.0 area 0 The configuration of R2 is as follows: Ip router isis encapsulation frame-relay There have been a lot of talks about ATT-bit before, so I won't be embarrassed here. I have tested on CISCO IOS Version 12.4(10) -- C3640-JK9O3S-M . On R1, which is L1 router , with default-information originate , I can't generate default route. The distribution of the label is like this: Interface eth 0/1 1.0.0.0/24 is subnetted, 1 subnets Record Route: NONE Ip cef The load of the routing processor is low in large areas R3.02-00 Interface Ethernet0/0 75000 I/E When there is a problem with the path of R1-R2-R5 , for example , the link between R2-R5 is DOWN , then the TE tunnel will switch to the path-option of the next priority , that is, the dynamic setting mode. Therefore, it will switch to R1-R3-R4-R5 . RFC 3719 1 10.1.12.2 12 msec 4 msec 4 msec RFC 3784 The main function of the ES-IS protocol is to provide mapping of NSAP addresses to SNPA addresses for network devices . Message 2.0.0.0/32 is subnetted, 1 subnets (Link ID) Network/subnet number: 2.2.2.2 (Link Data) Network Mask: 255.255.255.255 Number of TOS metrics: 0 *Aug 18 04:37:06.239: parameter id=127, flags=0, parameter length=5 Mpls traffic-eng router-id loopback0 mpls traffic-eng area 0 Bandwidth: 2000 The LDP neighbor establishment first sends the HELLO packet (the HELLO packet uses UDP , the source port is 646 ). The LDP ID is 6 bytes ( 4 bytes of IP plus 2 bytes of LABEL SpaceID ) 10.1.23.2 Allocation pattern (the Label Allocation) : independent control mode (Independent Control) 10.1.23.3 Ok, now when R1 is going to ping 4.4.4.4 , R1 has to check its own FIB , which is the CEF table. Note that this is an IP lookup: Interface eth 0/1 R1#show mpls ldp discovery detail This TLV , in this way,ccna training kit, provides a simple and reliable mechanism for advertising hostname information. As shown in the figure below, this is an LSP message: Metric , the tunnel 's Metric (for OSPF for the tunnel mouth Default cost = 1000 ) will link status information together with the notice to other neighbors, and also affects other routers routing. ! At 0XFFFFFFFF , this router will suspend the IS-IS process for MaxAge + ZeroAgeLifetime seconds, so that the LSP corresponding to this router in the entire routing domain is deleted. The IS-IS process is then restarted and the LSP is sent starting with sequence number 1 . (In fact, this situation will not arise, because even generate a per LSP , but also to 136 years after the serial number can be from 1 to reach 0XFFFFFFFF .
