The summary route is 10.1.0.0/16 and is advertised to B. ! Once LDP is activated, the LSR generates a label locally for the prefix in the routing table, and then bundles it with the prefix to send the label mapping message to all LDP neighbors. When I receive the remote binding from the LDP neighbor ,ccna exam questions and answers 2015 pdf, I bundle the tags and the local bindings that are localized for the specific prefix into the LIB . For the LAN interface, a 1- byte circuit ID is appended to the 6- byte SysID of the specified intermediate system ( DIS ) to form a 7- word. If the weight issue orders without the level parameter, the default is as shown level2 parameters, that is, inject external routes into level2 in this way level2 area can learn to this external routes, but level1 area in Can't learn because R2 is at level1 L1\L2 router will inject this external route in Level1 area and Bacbbone.

View MPLS forwarding table ( LFIB ) 75000 LDP discovery sources: Support for diagnosis of LSP tunnel Mpls traffic-eng tunnels ip rsvp bandwidth NSAP address to host name mapping Prefix The composition of the router , Backbone must be continuous. * 0x0000000F If a router has insufficient resources, it may not be able to maintain a complete link state database. Data traffic arriving at this device may not be able to be forwarded normally. Therefore, it has the ability to inform or alert other routers. The specific method is to It produces LSP in the Overload-bit set. It was set overload field that LSP does not diffuse in the network and is calculated by the overload routing the router will not use the LSP . In other words, overload router is bypassed transmission path ( Bypass ), and those with overload router as the last hop of the route (directly connected local network segment) involved in the calculation only. In addition, the white point is that the IS-IS router that receives the LSP can still generate a route to the direct connection of the overload router, but will not go to other destinations through this router.
