Since we have configured link protection on R2 to protect the link between R2-R4 , when the E0/1 port of R2 is shut down , the path error message sent by R2 to R1 indicates that R1 does not need to be removed. Drop the tunnel . So R1 of the tunnel will not be removed.

Which neighbor's remote label is it? The answer is C , because C is the next hop of the E router to X , and E will use the routing table to determine who's label bundle is "better". Next, let's take a look at the details of these LSPs : Router ospf 1 Hostname: R1 Router ID: Collects reachable NSAP prefix information, which is only used for inter-area ISO CLNP roads. In the default implementation mode, the IIH packet is filled to the outbound interface MTU size (using the method of adding padding , as shown above). The router compares the local interface MTU with the received IIH size to ensure that it can be processed before forming the adjacency. The largest possible packet of neighbors. The above command will add or subtract z from the original cost of the route ( the range of z is -10 to 10 ) *Aug 18 04:37:06.243: SESSION type 7 length 16: Routing information diffusion and database synchronization Network 1.1.1.1 0.0.0.0 area 0 R3#show ip ospf database router 2.2.2.2 Experimental needs Removal Trigger: configuration changed ... ... ... ...

In OSPF , the router on the LAN only establishes adjacency with the DR . MPLS label Labels 0-15 are all reserved labels. Here are some reserved tags that have a specific role: Ip access-list standard accept-ldp permit 1.1.1.1 0 kbits/sec The maximum number of regional addresses configured by a single router must be the same as that of neighboring neighbors. By default, CISCO IOS routers support the maximum number. SNPA ( Subnetwork point of attachment ) Reservable Bandwidth[4]: Is a group or flow of packets that are forwarded along the same path and are treated the same with regard to the forwarding treatment.

Since then a series of improvements and extensions have been made. The large-scale development of the IS-IS protocol in major ISP networks began in 1995 , and another important reason was the US government 's interest in ISO CLNS . Although integrated IS-IS has dual routing capabilities, it is interesting to note that most of today's world's largest ISP networks use IS-IS protocols only for IP routing.
