[Truncated Output] Walkthrough Figure 10.6 shows a packet leaving Host X destined for Host Y. Note that the next-hop MAC address belongs to Router A (using proxy ARP); however, the IP address belongs to Host Y. When the frame reaches Router B, the Ethernet header and trailer will be exchanged for the WAN protocol, which you can presume is HDLC here. Maximum number of concurrent server connections allowed: 16 Server idle time-out: 180 seconds VLAN and Trunking 5.4.d Login banner Cisco routers use the longest prefix match rule when determining which of the routes placed into the routing table should be used to forward traffic to a destination network or node. Longer, or more specific, routing table entries are preferred over less specific entries, such as summary addresses, when determining which entry to use to route traffic to the intended destination network or node. Router#show ip bgp ? The first step in troubleshooting routing is verifying that the routing protocol is enabled and properly configured. This can be done either by inspecting the current running configuration (i.e., the show run command) or by using show commands associated with each particular routing protocol. Some of these options are listed below: R1#show ipv6 interface brief R1#show ipv6 interface f0/0 R1#show ipv6 neighbors Router(config)#ip dhcp excluded-address 172.16.1.1 172.16.1.10 Router(config)# Verifying Dynamic Secure MAC Addresses R1(config)#ntp master ? exec-wait Delay EXEC startup on noisy lines finger Allow responses to finger requests 4.Issue an ipconfig /all command to check whether an IP address has been assigned to your PC. You may need to issue an ipconfig /renew command if an old IP address is still in use. ip route 192.168.1.0 255.255.255.0 Ethernet0/2 %LINK-5-CHANGED: Interface Vlan1, changed state to up another protocol. For example, RIP might consider a path that is only two hops long as the most optimal path to a destination network,cisco 350-501 book, even though the links were 64Kbps links, while advanced protocols such as OSPF and EIGRP might determine that the most optimal path to that same destination is the one traversing four routers but using 10Gbps links. show interface trunk Switchport: Enabled Administrative Mode: trunk Operational Mode: trunk Troubleshooting static routes Switch#show lldp neighbors Capability codes: You can verify the native VLAN with the commands (issued per interface) illustrated in the output below: VLAN Trunking Protocol (VTP) is a Cisco proprietary Layer 2 messaging protocol that manages the addition, deletion, and renaming of VLANs on switches in the same VTP domain. VTP allows VLAN information to propagate through the switched network, which reduces administration is permitted access to a switch port, as well as to limit the number of MAC addresses that can be supported on a single switch port. The methods of port security implementation described in this section are as follows: Switch1(config)#int FastEthernet0/4 Switch1(config-if)#switchport mode trunk Switch1(config-if)#switchport trunk allowed vlan ?

Verifying that the routing table is valid The Shortest Path First Algorithm 172.16.0.0 NTP uses the concept of a stratum to describe how many NTP hops away a 3.6.dFloating static Routing protocol algorithms operate using either a flat routing system or a hierarchical routing system. A hierarchical routing system uses a layered approach wherein routers are placed in logical groupings referred to as domains, areas, or autonomous systems. This allows different routers within the network to perform specific tasks, optimizing the functionality performed at those layers.
