2. Consider the routing table and ARP table below from a Cisco router. This router has two Ethernet interfaces: Ethernet0/0 and Ethernet0/1. R S Routerfeshow ip route 192.168.10.0/24 is directly connected, Ethernet0/0 192.168.11.0/24 [120/1] via 192.168.10.7, 00:00:11, Ethernet0/0 192.168.50.0/24 [1/0] via 192.168.1.5 C R 192.168.1.0/24 is directly connected, Ethernet0/1 192.168.2.0/24 [120/2] via 192.168.10.7, 00:00:11, Ethernet0/0 Router6>show arp Protocol Address Internet 192.168.10.7 Internet 192.168.1.1 Internet 192.168.1.2 Internet 192.168.1.5 Internet 192.168.1.1 Internet 192.168.1.18 Internet 192.168.1.20 Router6> 41 Age (min) Hardware Addr Type 0030.8540.c460 ARPA 000d.bd4f.1380 ARPA 000d.bd56.2080 ARPA 206 212 1 000c.2983.9ec2 ARPA 10 1 0015.171d.f3d0 ARPA 0015.1780 d1 ARPA 00c0.b773.867e ARPA 206 Interface Ethernet0/0 Ethernet0/1 Ethernet0/1 Ethernet0/1 Ethernet0/1 Ethernet0/1 Ethernet0/1 A route is marked with C (Connected) if the subnet is directly connected to the interface. A route is marked with R (RIP) or S (Static) if the subnet is reached through another router, also called next hop. The address of this router is the one you see after the "via" keyword in the routing table. When a packet arrives, the router checks the destination IP address of the packet to see in which network it falls. There are five entries in the routing table above. The networks are: 192.168.10.0/24, 192.168.11.0/24, 192.168.50.0/24, 192.168.1.0/24 and 192.168.2.0/24. Once the matching route is determined, the destination MAC address in the packet is changed: either put 1- the MAC address of the receiving host if it is a C (directly connected) network, or 2- the MAC address of the next-hop router if it is a S or R network. a) (5 points) Assume that this router receives a packet with destination IP address 192.168.2.5 i) ii) This packet will be sent out which interface (Ethernet0/0 or Ethernet0/1)? What is the value of the Ethernet (MAC) destination address in the packet that is sent out? (specify numerical value, not just a description) b) (5 points) Assume that this router receives a packet with destination IP address 192.168.1.5 i) ii) This packet will be sent out which interface (Ethernet0/0 or Ethernet0/1)? What is the value of the Ethernet (MAC) destination address in the packet that is sent out? (specify numerical value, not just a description) 2.
