Configured Areas: 1 MPLS LDP-IGP synchronization can be used to solve this problem. Note that the MPLS LDP-IGP solution cannot be used for BGP label distribution. The global configuration command metric-style wide allows the cisco router to run the appropriate IOS version to send LSPs carrying the width. Negotiating Label space Bandwidth: 0 Router ospf 1 Each LSP has a maximum expiration time ( MaxAge ) in the LSDB . If this time expires, if no new LSP is received. Global Pool Sub Pool Two addresses are configured on the R5 interface: 10.1.35.5 and 10.1.35.55 to simulate two different source hosts. !! activation level1 of MPLS TE You can specify the ciphertext lsp authentication of level1 or level2 to carry the cipher text authentication information on the LSP . Mpls traffic-eng tunnels ip rsvp bandwidth LOOP Detection 2.2.2.0 [115/20] via 10.1.123.2, FastEthernet0/0 3.0.0.0/24 is subnetted, 1 subnets 2.2.2.2/32 O The configuration of R1 is as follows: R2-PE1#show mpls ldp neighbor *Aug 18 04:37:06.239: version:1 flags:0000 cksum:7B25 ttl:255 reserved:0 length:132 55.55.55.55 and 5.5.5.5 will no longer take the tunnel . MOSPF extension provides support for IP multicast routing InLabel : - Net 49. 0001 .0000.0000.0001.00 The configuration of R2 is as follows: *Aug 18 09:06:07.919: version=0 length in words=10 PDUtype : PDU type. This is a 5- bit field that identifies the type of IS-IS packet. A value of 15 indicates L1 LAN IIH ; a value of 16 indicates L2 LAN IIH ; a value of 18 indicates L1 LSP ; a value of 20 indicates L2 LSP ; a value of 24 indicates L1 CSNP ; a value of 25 indicates L2 CSNP ; a value of 26 indicates L1 PSNP A value of 27 indicates L2 CSNP . Mpls traffic-eng router-id loopback0 mpls traffic-eng area 0 LSP ID LSPID LSP Seq Num LSP Checksum LSP Holdtime ATT/P/OL End LSP ID : End LSP ID . Indicates the last LSP ID of the LSP range described in the TLV field . To support regional repair Device Internet segment 10.1.xy.0 / 24 , where xy is the device number, X small y large Downstream active mode : Downstream Unsolicited Routers in the network must identify all in order to perform appropriate operations 1.0.0.0/24 is subnetted, 1 subnets Ok, now let's analyze, when R1 wants to send data to R4 's Loopback 4.4.4.4 , how the data is transmitted. First analyze the control level: EXP In the routing table, R3 goes to 1.1.1.1 and uses 10.1.34.4 and 10.1.23.2 equivalent load balancing. PATH NET For the first layer LSP database, you use the first 1 layer CSNP and PSNPs , for the first 2 used in the first layer 2 layer CSNP 17 After receiving the label from the tail router, the penultimate hop router uses the label as the outbound label of the TE tunnel , and assigns a label to the tunnel and places the label in the label object in the RESV message. Send it to its own upstream router. Network 10.1.23.3 0.0.0.0 area 0 Interface Loopback0 The subnet point of attachments is the point at which the subnet service is provided, which is equivalent to the second layer address of the corresponding Layer 3 address ( NET or NSAP ). usually 0xA538 Mpls traffic-eng tunnels mpls label range 200 299 Network 10.1.34.3 0.0.0.0 area 0 We see that R5-PE2 assigns a 505 label to VPN customer route 6.6.6.6 . Interface 1.1.1.1/32 Next, R2 receives the tag packet. R2 knows that this is a tag packet from the type field of the Layer 2 Ethernet frame header of this packet, so it looks for its own LFIB table: 0x2D6E 0 kbits/sec Uptime: 12 seconds Tunnel mpls traffic-eng path-option 10 dynamic MPLS TE traffic forwarding Priority 3 : 9375000 ! ! The NSAP address of ID49.0001 , which enables seamless, collision-free, and non-destructive reconfiguration of the router's new NSAP address. Attribute tag and affinity attribute 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 ,ccna model question papers with answers pdf, but also to 136 years after the serial number can be from 1 to reach 0XFFFFFFFF .
