Layer 1: Port Serial0/1/0 1. Serial0/1/0 receives the frame. Layer 2: HDLC Frame HDLC 1. The device de-encapsulates the payload from the HDLC frame and sends it to the upper layer. Layer 3: IP Header Src. IP: 192.168.1.2. Dest. IP: 192.168.0.2 ICMP Message Type: 0 1. The device looks up the destination IP address in the CEF table. Layer 3: IP Header Src. IP: 192.168.1.2, Dest. IP: 192.168.0.2 ICMP Message Type: 0 1. The CEF table has an entry for the destination IP address. 2. The device decrements the TTL on the packet. Layer 2: Ethernet II Header 0002.1732.6901 >> 000A.F3A8.111A 1. The next-hop IP address is in the adjacency table. The device sets the frame's destination MAC address to the one found in the table. 2. The device encapsulates the PDU into an Ethernet frame. Layer 1: Port(s): FastEthernet/0 1. FastEthernet0/0 sends out the frame.

Configuring IP Addresses A IP Address configure on a network system should work if you test all of your pings on the network and if you use the ip route on the routers where you type is the ip route of the IP Address,Subnet Mask and Serial number.

The unicast transmission is used to refer to one device which will send a message to another device in one to one communications. A unicast packet has a destination IP address that is a unicast address which will then go out to a single recipient froman source IP address that can only be a unicast address because the packet can only originate from a single source.This is regardless of the weather of an destination of an IP address which is a unicast,broadcast or multicast. A multicast is a transmission which is reduced by traffic that allows an host to send a single packet to a selected set of hosts that subscribe to a multicast group. A multicast packet is a packet that has a destination for a certain IP address which is a multicast address. IPv4 has reserved the 224.0.0 to 239.255.255.255 address and has a multicast range. Hosts can receive particular multicast packages called multicast clients and they use services which are requested by a client program to help subscribe to t
