The latest IOS version can be set to 255. If the maximum number of area addresses supported by the two routers is inconsistent, that is, the MAX.Areas field does not match, the IIH message is ignored .

L1 (inside the area) and L2 (in the area) Net 49. 0001 .0000.0000.0001.00 IS ( layer 0 routing ), then the router will look up the destination address and forward the packet along the best path. !! Use the dynamic calculation method to establish the tunnel PATH RFC 3719 State 100 . An MP-iBGP connection is established between R2 and R5 . 0xA339 i L1 2.2.2.0 [115/10] via 10.1.123.2, FastEthernet0/0 5.0.0.0/24 is subnetted, 1 subnets *Aug 18 09:06:02.699: Layer 3 protocol ID: 2048 We see that on R2 , about 5.5.5.5 and 55.55.55.55, the R5 is the "rear" network at the end of the tunnel . The outgoing interface is tunnel0 . This means that when R2 receives data destined for these two network segments, it is placed directly into the TE tunnel . Compared to the way static routes are placed, the advantages of autoroute are shown. RESV The IS-IS adjacency relationship is established differently for different network types. IS-IS supports the following two types of networks: If it is a frame relay primary interface or a P2MP sub-interface, it is required to be a fully interconnected PVC . For details, see the relevant sections of this document. Network 10.1.23.2 0.0.0.0 area 0 mpls traffic-eng router-id loopback0 mpls traffic-eng area 0 P Address Interface Tunnel0 ISO 10589 requires that the hello data be padded to the MTU size of the output interface , which means that the same MTU is usually used at both ends of the adjacency relationship. SRM and SSM are used to coordinate diffusion and database synchronization Just throw the next hop of the traffic that meets the conditions to the tunnel interface. Net 49.0001.0000.0000.0001.00 Explicit Route: 10.1.45.5 5.5.5.5 *Aug 18 04:37:06.239: Error Code: 24 (Routing Problem) Active Path Option Parameters: Egress LSRs — Egress LSRs receive labeled packets, remove the label(s), and send them on a data link. Ingress and egress LSRs are edge LSRs. Send PATH message to the downstream every 30S head end You can specify the ciphertext lsp authentication of level1 or level2 to carry the cipher text authentication information on the LSP . Reservable Bandwidth[7]: Experimental results: Path option 10, type dynamic (Basis for Setup, path weight 20) Pop tag Since the IP prefix in the IS-IS area is the leaf of the SPF tree, part of the route calculation ( PRC ) is more, usually this means that in one BW (kbps) CSNP (Complete Serial Number PDU ) * 0x0000002B Error metric About LDP and IGP synchronization 0x00000029 Impact of route summarization on MPLS Ip cef Bw[0]: RESV Net 49.0001.0000.0000.0002.00 Point2point *Aug 18 11:31:44.598: 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 . Regional separation Intermediate LSRs - Intermediate LSRs receive an incoming labeled packet, perform an operation on it, switch the packet, and send the packet on the correct data link. IS-IS packet format We see that the forwarding aspect of the data is this: TCP connection: 3.3.3.3.41954 - 1.1.1.1.646 Mpls traffic-eng tunnels ip rsvp bandwidth In CISCO IOS ,ccna routing switching pdf free download, a re-optimization of a TE tunnel is done every 1 hour by default . Receives packets from other L2 routers in the area and forwards the packets to the L2 routers of other areas according to the destination address (or to the L2 router of the same area ).

Or Tunnel Id PSNP Provide a loop-free network If the L1 / L2 router redistributed external routes to Level-1 , the Level1 area in you can learn the route, but R2 does not route injection Level2 area is Backbone of 5 C 10.1.24.0 is directly connected, Serial0/0 C 10.1.45.0 is directly connected, Serial0/2 C 10.1.34.0 is directly connected, Serial0/1 i L2 10.1.123.0 [115/20] via 10.1.34.3, Serial0/ 1 ! *Aug 18 11:31:44.598: *Aug 18 09:06:02.699: parameter id=127, flags=0, parameter length=5 Mpls ldp router-id interface [force] All Layer 1 routers must have a unique system ID in the zone Cisco Router 's ISO addressing The table eventually forwards this IP packet.

There are two options for R1 to R5 : MPLS TE tunnel Ip cef *Aug 18 04:37:06.239: The LSR route may receive multiple labels of a specific prefix ( distributed by multiple LDP neighbors), but he only needs to use one of them. The IP routing table is used to determine the next hop of the IPv4 prefix ( the construction of the LFIB needs one). IGP routing table, because the next hop of LFIB is calculated from the IGP table). The LSR uses this information to create its LFIB . The label bundled locally in the LFIB is used as an inbound label, and the label advertised by the LDP neighbor is used as an outbound label.
