Switch(config)# 3.On the left router turn LLDP off the interface. limit unnecessary peerings, as shown in Figure 10.10 below. This is done using passive interfaces, which prevents the router from forming routing adjacencies on the specific interface. This functions differently based on the specific routing protocol used but the behavior usually falls within the following two categories: Interface must be up/up Encapsulation must match both sides Outgoing update filter list for all interfaces is not set Incoming update filter list for all interfaces is not set Sending updates every 30 seconds, next due in 10 seconds Invalid after 180 seconds, holddown 180, flushed after 240 Redistributing: rip When using DTP in a switched LAN, the show dtp [interface ] command can be used to display DTP information globally for the switch or for the specified interface. The following output shows the information printed by the show dtp command: Some engineers become confused when their ACL doesn’t perform as expected. The router will look at the top line of the ACL, and if it sees a match, it will stop there and will not examine the other lines. For this reason, you need to put the most specific entries at the top of the ACL. For example, take the ACL blocking host 172.16.1.1: Enter configuration commands, one per line. End with CTRL/Z.

The router can then route packets received from one VLAN to another using these physical LAN interfaces. This method is illustrated below in Figure 10.12: Set an Enable Secret Password Generally speaking, the most common services to enable/disable are listed below with their descriptions in Table 9.1: Switch1(config)#enable password cisco Switch1(config)#do show run 　Gateway Distance Last Update Distance: (default is 120) R2#show ntp status 1.Create VLAN 10 for data and VLAN11 for voice traffic on the switch. 3.Configure the interface for VLANs 10 and 11. Most routing protocols offer the ability to turn off routing updates per interface. We covered the passive-interface command in detail throughout this guide. The actual behavior of this command will vary from protocol to protocol. For RIP, it will prevent route updates from being multicast from the interface it’s applied to, but incoming updates will be received and processed for use in the routing table.
