Physical Bandwidth: Physical bandwidth of the 100000 kbits/sec !! interface Router ospf 1 772 OutLabel : FastEthernet1/0, implicit-null RSVP Signalling Info: Record Route: NONE Each ES belongs to a specific area, when the ES finds the nearest IS by listening to the HELLO ( ISH ) grouping of the intermediate system . Interface loopback0 Interface Ethernet0/0 Send PATH message to the downstream every 30S head end Is-type level-2-only Mpls ip 2.2.2.2 The following is the message format of the IIH in the LAN : 0x0000000C We know that IS-IS actually recognizes two types of networks, one is peer-to-peer and the other is broadcast multi-access network. For NBMA , such as frame relay networks, IS-IS deployment should be cautious, to see what will be wrong: 10.1.12.2 8 msec 4 msec 0 msec LSP overview ! *Aug 18 04:37:06.243: average rate = 250000 bytes/sec, burst depth = 1000 bytes Seq# Checksum Opaque ID Can be modified as the basis for calculating the shortest path of the TE tunnel Interface Loopback0 router Interface Tunnel0 1.1.1.1:0 Min unit = 0 bytes,max pkt size = 1500 bytes Ip vrf forwarding VPN-A Next Hop Interface loopback0 Router-id 5.5.5.5 The configuration of R4 is as follows: Since OSPF is inherently designed to support IP routing, and IS-IS still has some vendors' devices that are not perfectly supported, OSPF is still preferred for a significant portion of the network . However , interest in using integrated IS-IS for IP routing is increasing, and most ISPs in Europe use IS-IS . Many new ISPs are also considering deploying IS-IS . 0 kbits/sec In the standard SPF algorithm, there can be multiple equivalent paths to the same destination. We call it ECMP ( Equal-cost Multipath ). Ip rsvp bandwidth 2000 This command sets the total reservable bandwidth of the interface to 2M. The configuration of R5 is as follows: Interface 13 FastEthernet1/0, Src IP addr: 10.1.13.3 R2#sh isis neighbors Remove ( PoP ) 3bit experimental bits for QoS If the ES and the IS have the same area ID , then all ESs in the same area will establish an adjacency with the layer 1 router on the shared medium . Ip rsvp bandwidth 2000 500 behind 500 is for a single stream, limited to 500K 0x2995 We know that IS-IS actually recognizes two types of networks, one is peer-to-peer and the other is broadcast multi-access network. For NBMA , such as frame relay networks, IS-IS deployment should be cautious, to see what will be wrong: Router isis The first 6 is the setup priority and the second 6 is the hold priority . *Aug 18 09:06:02.699: 10.1.12.2 (Strict IPv4 Prefix, 8 bytes,ccna career, /32) Explicit Route: 10.1.23.3 10.1.34.3 10.1.34.4 10.1.45.4 This NSAP address is still a bit longer, and it is inconvenient to use. The SystemID is mainly used to identify several attributes, such as adjacency information, LSP identifier in IS-IS database, etc. In most cases, We are more suitable for symbols that have literal meanings, such as R1 and R2 , rather than a string of numbers. So CISCO IOS provides us with a very good way: the mapping of the router hostname to the NSAP address. Essentially the mapping of hostname to SystemID . There are two methods of static mapping and dynamic mapping.
