The show isis database detail Command
The show isis database detail command shows the complete LSP and the values for the individual fields. The command has the same syntax as the show isis database command in the preceding section. Example 10-12 shows output for the show isis database detail command. The example shows, for each LSP, the area and the IP address of the transmitting interface and the metric cost to the IP routes it knows. The default metric is a cost of 10; therefore, a metric of 20 indicate..
This section explains two key rules that a PIM-DM router must follow to decide when it can request a prune. Before explaining another example of how PIM-DM reacts to changes in an internetwork, a couple of new multicast terms must be defined. To simplify the wording, the following statements define upstream router and downstream router from the perspective of a router named R1. ■ R1’s upstream router is the router from which R1 receives multicast packets for a particular..
Three broad categories of CAC tools exist: 1. Local The node makes an admission decision based on local information or conditions at the node. 2. Measurement-based A decision on admitting a new flow is reached based on a combination of configuration information and reported information of other entities (such as calls, sessions, flows, bandwidth, memory use, and time slots). 3. Reservation-based Reservation of resources i..
Configuring OSPF for IPv6 is similar to the IPv4 configuration: Router1#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router1(config)#ip cef Router1(config)#ipv6 cef Router1(config)#ipv6 unicast-routing Router1(config)#ipv6 router ospf 1 Router1(config-rtr)#router-id 1.0.0.1 Router1(config-rtr)#area 0 range AAAA:5::/64 Router1(config-rtr)#exit Router1(config)#interface FastEthernet0/0 Router1(config-if)#ipv6 address AAAA:5::1/64 ..
Automatic summarization, also called auto-summary, causes a router to automatically advertise a summary route under certain conditions, without the use of the ip summary-address command. When using auto-summary, if a router has interfaces in more than one Class A, B, or C network, then that router will advertise a single summary route for an entire Class A, B, or C network into the other classful network, rather than advertise routes for the individual subnets. The following ..
