ccna routing and switching practice questions

Router(config)#Ip cef One goes from tunnel0 , cost=1000+1=1001 one goes from eth0/1 , cost=10+10+10+1=31 906 1178 Experimental procedure Pop Label Router-id 4.4.4.4 Ip unnumbered Loopback0 tunnel destination 4.4.4.4 tunnel mode mpls traffic-eng Now let 's take the traffic going to 4.4.4.4 on the R1 to the tunnel , using one of the simplest methods: static routing. But if we modify the configuration on R1 : Router(config)# mpls ldp discovery holdtime seconds Then apply the ACL on R2 , connect to the interface of R1 ,ccna routing and switching practice questions, in the direction Remote binding: tsr: 2.2.2.2:0, tag: imp-null No synchronization IS-IS Adjacency related packets debugging is on R1# *Aug 18 11:26:02.546: Bytes Label Mpls label rangempls label range 400 499 interface fa0/0 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 . View and verify Not triggered by ISH , once the interface is activated, the router floods the IIH message on the interface. Tunnel mpls traffic-eng path-option 10 dynamic 0/0/0 TE 's policy routing is no different from traditional policy routing, and it does not change the routing table traffic forwarding based configuration policy. Interface eth 0/2 Next-address 10.1.23.3 (Link ID) Designated Router address: 10.1.23.2 (Link Data) Router Interface address: 10.1.23.2 Number of TOS metrics: 0 !! Let R1 become DIS The existence of the established tunnel has changed. The network environment at this moment is as follows: Note that this so-called highest arbitration takes effect only if the TE metrics of multiple paths are equal, the available bandwidth meets the requirements, and there is no interference from other link attributes. The first one in the highest arbitration: select the path with the smallest IGP cost . This is the cost of the iGP . Note that it is different from the TE metric . The TE metric is the same as the IGP cost by default . Of course, we can also use the physical interface. Make changes.
