Mpls traffic-eng tunnels ip rsvp bandwidth *Aug 18 04:37:06.239: Ip cef MPLS TE component 4.4.4.0/24 Overview Peer-to-peer network Net 49.0001.0000.0000.0002.00 AutoRoute: disabled LockDown: disabled Loadshare: 0 bw-based auto-bw: disabled We open interface authentication between R1 and R2 : The above figure encapsulates a three-layer label package. For an LSR , only the first label is processed. Each layer of the label has a bottom of the BoS stack to indicate whether it is already the bottom of the stack of the label, and the last label has BoS=1 . Meanwhile, in order to avoid loops, R2 in the area level1 when injected these routes will be marked downbit , As a result, R3 receive this LSP , for these routes, it will not flood the backbone inside. Interface eth0 1/0 Overview Therefore, the MPLS VPN environment, if we MPLS VPN Backbone inherent R1 to R5 establish a TE the Tunnel , is not 105 All tag mapping messages received locally from the neighbor are saved in the database. *Aug 18 09:06:07.919: peak rate =250000 bytes/sec We see that R1 has learned to 2.2.2.0 , 3.3.3.3.0 and 10.1.24.0 , 10.1.34.0 .

But the forwarding adjacency feature is different. Moreover, the two methods of modifying the metric are not used. The autoroute needs to match the autoroute keyword to modify the metric and only affect the configurator itself. In the forwarding adjacency, the metric is modified directly in the tunnel interface . For example , if ISIS is used , then the isis metric command. If ospf is used , it is ip ospf cost .
