MPLS coding Different TLV field values ​​can be included in the LSP to advertise various different routing information. Et0/1 The NSAP or Net address is used to distinguish devices. In ISO terminology, the data link layer address ( LAN MAC ,ccna exam guide, Frame Relay DLCI, etc.) is referred to as subnet point of attachments ( SNPA ). Since a network device may be connected to multiple links, multiple SNPA addresses are required, but only one OSI network address is required . 10.1.34.4 3 Tag or VC Maximum reservable bandwidth : 9375000 Number of Priority : 8 Remove: The top label is removed. The forwarding of the message depends on the remaining tags in the tag stack, or it is forwarded as an unlabeled message. !! TE metric , the default is equal to the following IGP metric Prior LSP: Define source R2#show mpls traffic-eng link-management advertisements Show isis lsp-log Mpls traffic-eng tunnels mpls label range 100 199 TE 's policy routing is no different from traditional policy routing, and it does not change the routing table traffic forwarding based configuration policy. The maximum reservable bandwidth is 75M , which is 75% of 100M . Clns host RouterA 49.0001.1111.2222.3333.00 clns host RouterB 49.0001.4444.5555.6666.00 1.1.1.1 Manually reoptimize 16 Interface eth 0/2 IS-IS supports plain text and cipher text MD5 authentication. Let's make a small summary below: As long as the route prefix is ​​learned locally through the IGP , the route prefix is ​​assigned a label ( locally also assigns a POP label to the direct route ) *Aug 18 09:06:02.699: Token bucket fragment (service_id=1, length=6 words ! i L1 2.2.2.0 [115/10] via 10.1.123.2, FastEthernet0/0 10.0.0.0/24 is subnetted, 2 subnets Ip router isis 0/0/0 Interface Tunnel0 Network 2.2.2.2 0.0.0.0 area 0 Ip cef Type 9 flooding range only on this link IGP Area[1] ID:: ospf area 0 System Information:: Looking at the above topology, we need to establish a TE tunnel between R1 and R5 . Under normal network conditions, we want the tunnel path to be R1-R2-R5 , which is an explicit specified path. In order to make the tunnel path have a backup, we can define a path-option , this path uses the dynamic setting method, let CSPF calculate it by itself, then the configuration is as above. For the setting of SystemID , it is customary to encode the interface MAC or IP address of the router into a system ID or a part of it. Loopback IP is commonly used for this purpose in integrated IS-IS . For example, I have configured a loopback : 192.168.1.24/32 , and then I will complete this IP , not enough 3 digits to add 0 in front , forming 192.168. 001.
