The ACL filters out LDP packets. This prevents LDP adjacency between R1 and R4 from being established. Let's observe the phenomenon. Reservable Global Pool BW: 75000 kbits/sec Integrated IS-IS ( IS-IS ) enables the IS-IS protocol to propagate routing information for protocols other than CLNP .

If a router does not recognize a TLV , it will be ignored. *Aug 18 09:06:07.919: SESSION_ATTRIBUTE type 7 length 16: Note: a FEC can contain multiple streams, but not a stream of a FEC , such as looking at a host Sina website, which is a stream and looking at Sina's video, which in turn is a stream, the two streams When Sina sends to a remote host, the path should be the same, so one FEC has multiple streams, but each stream does not belong to a separate FEC.

CSPF calculates the path 4B is an unsigned integer. Starting from 0 , increase by 1 each time . When a router is first connected to the network, the sequence number of the first LSP it generates is 1 . The LSP sequence number generated when the network changes is also incremented by 1 . The LSP sequence number plays a key role in the data synchronization process, mainly in distinguishing between old and new LSPs .

In the figure above, the red path is calculated by CSPF . The configuration of R2 is as follows (all configurations are omitted from the configuration of interface IP ): In R1, this L1 router attempts to perform route summarization. The result is a failure. This is similar to OSPF . Routers in the area cannot be routed. Because we want to flood the LSP , the routers in the area must know the area. For details of the topology,ccna rack rental, if the L1 router is allowed to perform route summarization, does it lose the nature of the link state routing protocol?

Eventually this data was passed to R4 . R2.00-00 Router ospf 1 The R2 re-released 2.2.2.0 external route is still there; the inter-area route is gone, except for a R2 local direct connection of 24.0 ; in addition, R1 still does not use R2 as the next hop of the default route.

Going is the tunnel . therefore: 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. Mpls ip interface fast1/0 Mpls traffic-eng signalling advertise implicit-null [acl x] 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.
