The routing table of R3 is as follows (omit direct route): Outgoing !! Set overload-bit to suppress external routing ! The configuration of R3 is as follows: Version:1 flags:0000 cksum:7931 ttl:255 reserved:0 length:132 !! It can be seen that the f0/0 port has been separated by 33M. *Aug 18 09:06:07.919: Path MTU: 4294967295 Or Tunnel Id For certification The default on the point to point link 10S sent once IIH . On C , first look up the LFIB table and find that the label is to be popped up, so it will pop up the label and pop up and find it is an IP packet, so go check FIB again. Ip router isis ! Downstream on-demand mode : Downstream On Demand The TTL is placed in the label header. Turning off TTL propagation prevents the MPLS network from being exposed (by traceroute ). O 2.2.2.2 [110/2] via 10.1.23.2, 00:09:07, FastEthernet0/0 Fa0/0 Last update from 10.1.123.2 on FastEthernet0/0, 00:01:32 ago Routing Descriptor Blocks: Router-id 2.2.2.2 7 Tib entry: 10.1.34.0/24, rev 12 A label switch router (LSR) Label space (the Label Space) : based platform (Per-Platform) The loopback interface of R2 and R3 comes from this area, so there is no problem with the route of L1 ,ccna 1 practical exam, but is the direct link of R2-R4 and R3-R4 coming in? That's because these are the direct connections of R2 and R3 . You can configure the interface to be on S1 and 0 of R2 and S1/0 of R3 . *Aug 18 09:06:07.919: Tun Sender: 1.1.1.1 LSP ID: 247 It has been verified by experiments. Use debug mpls traffic-eng tunnels events and debug mpls traffic-eng tunnels reoptimize . ! Downstream on-demand mode : Downstream On Demand Detailed LSP header Fa0/0 Active Now, shut down the e0/1 port of R2 . Let's take a look at the routing table for R1 : Remote binding: tsr: 2.2.2.2:0, tag: 202 tib entry: 10.1.23.0/24, rev 12 Traditional IP routing only considers metric when routing . For example, if we are running OSPF in the above figure , then R1 to 1.0/24 and 2.0/24 will preferably be from R2 to R3 . Path because the metric is small. Then this directly causes the idle of another optional path and the excessive congestion of the main path. The maximum bandwidth is the total bandwidth of the link. In CISCO IOS , this value matches the physical link or the configured bandwidth value. AutoRoute defect 302 BW (kbps) ! The maximum reservable bandwidth is 75M , which is 75% of 100M . OSI network layer addressing is achieved by using two types of hierarchical addresses: NSAP and NET . <0x0-0xFFFFFFFF> Attribute flags 3.3.3.0/24 Note that this 303 obviously, is R3 assigned to this allocation result and then to R4 , R4 is with R3 label assigned to pressure to MPLS TE overview FastEthernet0/0 (ldp): xmit/recv Enabled: Interface config 1.0.0.1 OSPF Therefore, the main functions of RSVP are: If the MPLS payload is an IPv4 or IPv6 packet, CISCO IOS is used in a destination-based load balancing environment. Local binding: tag: imp-null 10.1.123.3 The NSAP address of ID49.0001 , which enables seamless, collision-free, and non-destructive reconfiguration of the router's new NSAP address. We know that by default, IS-IS is level1 area much like a Stub (but allow people to re-advertise external routes coming in, so just say they look like), Area within the L1 router through a default route to reach outside the region, which have A suboptimal path may be generated because he is looking for the nearest L1\L2 router in the region .
