The configuration of R5 is as follows: Object name *Aug 18 11:31:44.598: The LFIB table does not contain inbound interface information. Finally, let's complete the configuration of R1 : An IS-IS router can be configured to summarize IP routes into Level 1, Level 2, or both, at the same time, Admin: up 697 Partition repair *Aug 18 11:31:44.598: 75000 The TLVs used are: R1#show ip ospf database opaque-area self-originate Mpls traffic-eng tunnels ip rsvp bandwidth Bandwidth: 2000 Environmental description 10.1.12.2 4 msec 4 msec 0 msec Fspec: ave rate=2000 kbits, burst=1000 bytes, peak rate=2000 kbits History: *Aug 18 04:37:06.239: Peak rate 0 packets, 0 bytes Peak rate Interface fa0/0 !! Backup tunnel i L2 5.5.5.0 [115/20] via 10.1.45.5, Serial0/2 10.1.35.5 -> 1.1.1.1 : FastEthernet1/0 (next hop 10.1.34.4) AutoRoute metric Ip address 2.2.2.2 255.255.255.255 5 1.1.1.1 Only support IP Network Entity Title is the last byte 0 of the NSAP , it is a device identification ( the NSAP port number is 0 thing). So every router is This will cause R2 to calculate the route, from the tunnel0 port to the 5 and 55 route metric becomes 32+1=33 , which is greater than the metric=31 of the route taken from e0/1 . So the routing table of R2 has changed, and the routes of the 5 and 55 network segments have become: Metric: 0 The loopback0 address space of all devices is xxxx/32 , and x is the device number. Run OSPF on the entire network to announce direct connection and loopback interface. lab environment Router-id 1.1.1.1 0/0/1 State: Oper; Msgs sent/rcvd: 26/22; Downstream Up time: 00:09:33 10.1.12.2 TE metric is a parameter used to build a TE topology that is completely different from the IP topology (although by default it is equal to IGP metric ) *Aug 18 11:31:44.598: Tspec: ave rate=20000 kbits, burst=1000 bytes, peak rate=20000 kbits RSVP Resv Info: 4.4.4.0/24 Remote binding: tsr: 2.2.2.2:0, tag: 200 This time we did the test, environmental test just a different,ccna exam structure, TE the Tunnel tail end now is to R4 of 4.4.4.4 . 0 kbits/sec Destination-based load balancing is actually achieved by HASHing the destination and source IP addresses . In other words, it is actually based on source and destination address pairs for load balancing. 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 .
