*Aug 18 04:37:06.239: Controlled Load Service break bit=0 service length=0 R2.00-00 Election DIS . In this network, the DIS will generate and flood the new pseudo-node LSP on each of the routing layers it participates in (whether L1 or L2 ) and on each LAN it is connected to . Each router on the LAN establishes adjacency with all other routers and DISs , and does not elect to back up the DIS router. The elected DIS does not guarantee that it will always be DIS . The configuration of R1 is as follows: 102 Complete basic IP configuration (configuration omitted) Pop tag Interface tunnel0 Tunnel destination 4.4.4.4 tunnel mode mpls traffic-eng State !! Bandwidth requirement is 20M *Aug 18 11:26:02.546: *Aug 18 09:06:02.699: Layer 3 protocol ID: 2048 CLNP is similar to the IP protocol except that it serves the ISO transport layer. IS-IS ,ccnp switch sample questions, ES-IS , and CLNP are network layer protocols that are encapsulated directly in the data link layer frame. Compared with the OSPF packet in TCP/IP , it is hidden behind the IP header. The encapsulation efficiency of the former protocol packet is higher. If the bandwidth parameter is not followed by the command, the "reservable bandwidth" of the interface defaults to 75% of the physical bandwidth of the interface . *Aug 18 04:37:06.243: tspec parameter id = 127, flags = 0, length = 5 MPLS technology architecture We found that the attached-bit before the LSP generated by R2 is gone, but the Overload-bit is set . Now let's go look at the routing table. The unit of the OSI protocol stack defining data is the protocol data unit PDU , so the OSI view data frame is the PDU of the data link layer . 75000 kbits/sec, If a tunnel1 establish priority than the tunnel2 high hold priority, then tunnel1 be able to seize tunnel2 Version:1 flags:0000 cksum:7931 ttl:255 reserved:0 length:132 UP My Address: 10.1.12.1 Interface fas1/0 [115/20] via 10.1.24.2, Serial0/0 MPLS LDP-IGP synchronization is enabled in the IGP process and applied to all interfaces running the IGP . Ip router isis 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 .
