4.Now ping the remote network on R1 from R2. Inter-VLAN routing using physical router interfaces Inter-VLAN routing using router subinterfaces trunk link because routers don’t support DTP. If the trunk is configured as an 802.1Q trunk, a native VLAN must be defined if a VLAN other than the default will be used as the native VLAN. This native VLAN must also be configured on the respective router subinterface using the encapsulation dot1Q [vlan] native subinterface configuration command. The leasing process has a number of timers associated with it,spoto ccie lab r&, so you can be sure that you are always going to have an IP address that is updated on every network device. The two important DHCP timers are as follows: Switch1(config)#no cdp run DTP is a Cisco proprietary point-to-protocol that negotiates a common trunking mode between two switches. This dynamic negotiation can also include trunking encapsulation. The two DTP modes that a switch port can use, depending upon the platform, are as follows: hold down, and flush, which were already discussed. SwitchOne(config)#ip ssh authentication-retries 2 Learn how to configure voice VLANs on a Cisco switch. Path Length Figure 10.7 shows the same packet leaving Router A for Router B. There is a route lookup and then the packet is switched out of interface E1. Type 800 indicates that the packet is IPv4. neighbor Neighbor list Gi0/2 1 1 0 Shutdown ------------------------------------------------------------------ R2#show ntp associations Router(config)#ip host R2 192.168.1.2 Router(config)#ip host R3 192.168.1.3 Router(config)#exit The following line of configuration will add VTP pruning to your switch: Packet Forwarding su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area, * - candidate default, Switch#show port-security interface FastEthernet0/1 Port Security : Enabled Router(config-subif)#int g0/1.20 Router(config-subif)#encap dot In the output above, a single client was served by the DHCP server and was assigned the first non-excluded IP address from the DHCP scope: 192.168.1.2. You can also see the lease expiration date and the device MAC address. Maximum number of requests allowed on a connection: 25 HTTP server active session modules: ALL Read the ICND1 cram guide Take today’s exam You can also add an IP address to the switch to allow you to Telnet to it for management purposes. This is referred to as a Switch Virtual Interface (SVI). It is a wise precaution to have this management access in a VLAN other than VLAN 1, as shown in the output below: You can also use the following debug commands as part of your troubleshooting process: Switch(config)#interface vlan1 As stated earlier, Cisco IOS software allows administrators to specify four different actions to take when a violation occurs, as follows: Please note that your switch will need to have a security image which permits basic security settings. that their connectivity to the core site is very slow. What happened? N2 - OSPF NSSA external type 2, E1 - OSPF external type 1, E2 - OSPF external type 2, E – EGP, i - IS-IS, 2.Copy and paste the ACL into Notepad and edit it there. Switch#conf t Network administrators who want to configure a DHCP server also need to configure DHCP scopes as part of this process. A scope is a grouping of IP addresses for a particular section of the network. Each subnet usually has its own scope. Entry address(es): Hop count limit: This parameter marks routes as unreachable when they are more than a predefined number of hops away. The hop count limit for RIP is 15, as it is not usually used in large networks. Unreachable routes are not installed in the routing table as best routes. The hop count limit prevents updates from looping in the network, just like the TTL field in the IP header. DTP is a Cisco proprietary point-to-protocol that negotiates a common trunking mode between two switches. DTP will be described in detail later. The following output illustrates how to configure a switch port to use IEEE 802.1Q encapsulation when establishing a trunk: --------- ----------------- -------------- Switch#show ip ssh show interface trunk 4.Add a next hop address for network 172.16.1.0/30 Known via “static”, distance 1, metric 0 Routing Descriptor Blocks: Walkthrough Now that you understand network routes from the previous section, it will be relatively easy to learn about host routes. A host route is a route for a single host address. It will always have a /32 subnet mask. As with network routes, the ip route command will create static routes for remote hosts by using a mask of 255.255.255.255. Here is an example: 7.Confirm you have exit interface and next hop listed 3.5Compare and contrast static routing and dynamic routing 5.Your IT manager changes his mind and wants only SSH access, so change this on your VTY lines. Only certain models and IOS versions will support the SSH command. Switch(config-if)#switchport nonegotiate Switch1(config-if)#exit Switch1(config)#no lldp ? run Enable LLDP Switch1(config)#no lldp run RouterB#ping 172.16.1.1 Type escape sequence to abort. Cisco IOS Software, C2960 Software (C2960-LANBASE-M), Version 12.2(25)FX, RELEASE SOFTWARE (fc1) An err-disabled port might look something like this: Switch(config-if)#switchport trunk encapsulation dot1q Switch(config-if)#switchport mode trunk Switch(config-if)#switchport nonegotiate Switch(config-if)#exit Switch-1(config-if)#switchport port-security maximum 2 Router#show ip ospf ? R2#show ntp status Most RIP issues are related to the administrator mistyping commands or misunderstanding VLSM. We will cover IP troubleshooting later on, but double-check that your router interfaces are up (physically and logically). Check that your IP address and subnet mask are correct as well. Pinging 192.168.1.1 with 32 bytes of data: The native VLAN is another important element that you should verify on the trunk ports. Misconfigured native VLANs can lead to a lack of functionality or security issues. The native VLAN should match at both ends of the trunk links.

This parameter is usually administratively configured inside the DHCP scope. Whenever a client reboots it will have to ask the DHCP server again for an IP address. The DHCP server is usually configured to re-allocate the same address and extend the lease for the specific client.
