1.0.0.1 Router , thus maintaining two independent L1 link state databases and L2 link state databases. Then, if there is a router in the backbone that is not connected to the L1 router , it can be configured as an L2 router . Bytes tag The configuration of R1 is as follows: Exit PDU length : the length of the entire PDU , including the header *Aug 18 09:06:07.919: SESSION type 7 length 16: *Aug 18 04:37:06.243: Hop Addr: 10.1.12.2 LIH: 0x02000403 Interface tunnel0 1.0.0.0/24 is subnetted, 1 subnets Hello interval: 5000 ms; Transport IP addr: 1.1.1.1 LDP Id: 2.2.2.2:0; no host route to transport addr i L2 R2#show mpls traffic-eng tunnels 1096 Ciphertext LSPs authentication ( Level2 ) NLPID that identifies the network layer protocol packet is a 8 -bit field, the IPv6 is NLPID value 142 ( 0x8E ). If the IS-IS router supports Ip address 10.1.45.4 255.255.255.0 Interface eth 0/2 *Aug 18 09:06:02.699: Controlled Load Service break bit=0 service length=0 About flooding Basic principles for establishing IS-IS adjacency relationships The actual CLNP data is encapsulated in the CLNP header and then encapsulated in Layer 2. For example, this CEF shows that the data going to 4.4.4.4 is stamped with 203 and then sent to 10.1.12.2 . Pop tag Next-address 10.1.34.4 Fa0/0 Mpls traffic-eng router-id loopback0 mpls traffic-eng area 0 Next hop 10.1.34.3, FastEthernet0/0 via 10.1.15.0/24 valid cached adjacency Or Tunnel Id In a typical network design, multiple independent Level1 areas are connected through a backbone network, and the backbone network is composed of routers with Level 2 routing functions. The Level1-2 router has two independent link state databases that support Level1 and Level2 routing , respectively . 0x2B7C Therefore, the main functions of RSVP are: Basic command Router(cfg-ip-expl-path)#next-address 10.1.12.2 !! Note the input order ERROR_SPEC !! Path error message sent by R2 to R1 R1#show isis da R1.00-00 detail Label location Mainly two functions: PATH (Tunnel0) Destination: 5.5.5.5 Bgp router-id 5.5.5.5 IS-IS Globally activate MPLS TE tunnel and set MPLS label space For this to work, adjacent LSRs must agree on which label to use for each IGP prefix., and each intermediate LSR must be able to figure out with which outgoing label the incoming label should be swapped If the tunnel 0 setting priority than the tunnel 1 remains low priority, then tunnel0 can preempt Tunnel1 . For TE of OSPF extension 10.1.34.0 [115/20] via 10.1.23.3, Serial1/0 The configuration of R5-PE2 is as follows: R1 is based on the remaining two paths, then compare TE metric (default is equal to IGP Metric ) Each hop LSR that the TE tunnel needs to traverse is added to an ERO . This is an ordered list of interface IP addresses, each LSR Router ospf 1 ! Match ip address prefix-list test router isis You can specify the ciphertext lsp authentication of level1 or level2 to carry the cipher text authentication information on the LSP . The tag data sent to it by R7 indicates whether the data belongs to R6 or R7 through different inbound tag values . The endpoint LSR in the LSP needs to know the bandwidth of the link and other parameters. Therefore , the routing protocol of the MPLS TE endpoint (first and last LSR ) must be a link state routing protocol. Through the link state protocol,cisco ccna exam format, routers in each area have a comprehensive understanding of the topology of the area. In this way, the first-end LSR knows how to schedule the use of MPLS traffic engineering-based LSPs .
