CMIT 350 Routing lab. Name(s): ___________________________________ Use the appropriate commands to do these. On all of the routers set the interfaces' IP addresses but do not enable the RIP routing protocol. Can A ping B's S1 interface:____ Can A ping B's S0 interface:____ Can A ping B's E0 interface:____ Which networks are in A's routing table:______________________________ What "code" of network are they:______________________________ A knows a packet for 201.100.11.2 (i.e. B's S1) must be in the 210.100.11.0/24 network and so sends it out its S0 because that is where the 210.100.11.0/24 network is. A doesn't know that 201.100.11.2 is at the other end of its S0 or that B's S1 is there. Does A know anything about networks 199.6.13.0/24 or 219.17.100.0/24:____ So, even though A can "get to" B via the 201.100.11.0/24 network it can't get to the "far sides" of B because it doesn't know anything about that far side. A doesn't know where the 199.6.13.0 and 219.17.100.0 networks are, so any attempt to ping/access them goes nowhere; A won't send the packet out any interface. Do you think A can ping/access any other router:_____ None of the routers can now access anything except what's on their connected networks. [On A, add a static route to B's E0 network: Blast! this simulator doesn't support ip route command, so skip this section. ip route 219.17.100.0 255.255.255.0 201.100.11.2 "to get to the 219.17.100.0/24 network, go to B's S1" This static route will now be in the routing table. A will be able to ping B's E0 interface. ] [On A, add a default gateway of B's S1 interface. Blast! this simulator doesn't support ip default-gateway command, so skip this section. ip default-gateway 201.100.11.2 "if I don't know a route [and no routing protocol is enabled], send packet to B's S1" A will be able to ping B's E0 interface and anything that B knows to get to. If RIP routing is enabled, use the ip default-network command instead to define the gateway of last resort. Blast! yeah, unsupported, skip. ip default-network 201.100.11.0 "the route to this network is the default route, i.e. use it if there's nothing else" A will be able to ping B's E0 interface and anything that B knows to get to. ] Enable RIP on A and B. Have A advertise all three of its networks, but have B advertise only its S1 and E0 networks. What has been added to A's routing table:__________________________________ What "code" is it:_____________ The [120/1] is the administrative distance and the hop count. To get to this network, what interface will be used and to what address:_______________________ Does A know that B has an E0 interface:_______ Why wasn't B's S1 network added to A's routing table by RIP:______________ Can A ping B's E0 interface now:____ Can A ping B's S0 interface now:____ On B, add its S0 network to the RIP advertisements. What has been added to A's routing table:_____________________________ Can A ping B's S0 interface now:____ Can A ping C's S1 interface:____ Can A ping C's S0 interface:____ Enable RIP on C, D and E, adding all their networks. How many network routes has A learned about thru RIP:_____ How many hops is the furthest network from A:_____ Do a traceroute from A to E's E0. How many hops:____ Are all the interfaces along the path mentioned:____ How would you categorize/describe the interfaces that are used along the path:________________________________________________ How many hops from A to the far side of B:_______
