Modify the ldp hello message sending interval, the default 5S 4 is IPv4 . If it is 6 or IPv6 , the LSR uses this value to determine whether the message is V4 or V6 , and then selects a complex equalization algorithm according to different IP versions. Area Address: 49.0001 16 Router(config-if)#tunnel mode mpls traffic-eng RFC3209 RSVP-TE Extensions to RSVP for LSP tunnels describes the extension of MPLS TE function by RSVP protocol . Host MPLS TE status Interface eth 0/2 Impact of route summarization on MPLS Interface tunnel0 Look at the example above: A is in the area 49.0001 , B is in 49.0002 , because they are in different areas, so they become Level 2 adjacencies. Maintain adjacencies in the region at the same time. If A is configured: R4 routing table: Integrated IS-IS and OSPF are 20 century 80 late-defined, which is about 1988 years. OSPF actually evolved from an earlier version of IS-IS , but it uses IP as a precondition. The core concepts of OSPF , such as the proliferation of link state information, the SPF algorithm, and the use of designated routers in the broadcast link, are borrowed from the IS-IS early version. Set-overload-bit suppress interlevel external Basic Experiment 1 ( OSPF ) Interface Loopback0 Or Tunnel Id Every downstream neighbor 30S sending RESV message Ip cef State: Oper; Msgs sent/rcvd: 9/9; Downstream !

Eventually this data was passed to R4 . Is-type command such as is-type level-1 The metric configuration only affects the tunnel endpoint router itself, and does not advertise to other neighbors. 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 ,ccna book pdf, it is ip ospf cost .
