Restoring IOS and issue of lack of PCs

hi, all. i have not been here for a long time.

REAL LAB (not a simulator)

Case- i had a lab in order to implement a very basic VLAN between two switches separately connected to two cisco 1700 routers.
What is required from me was establishing communication of VLAN1; VLAN 2 on a switch under a single 1700 with the one other.
(inter-vlan routing)

what i did is!

. i performed the back-to-back communication part between routers. Broke their forgotten passwords. Allowed two routers to speak each other.

.connected to each switch and renewed their configurations. assigned VLANs.

. connected to the router on the left and set the encapsulation and assigned IP addresses for each VLAN of the PCs under this router (subif)

what i couldn't!

.connected to the router on the right. however, encapsulation command didn't work on this.

. need at least four computers to link them with routers.

Question 1 ) how to set up computers when there is only one laptop?

Question 2) how to solve the issue of encapsulation command? IOS restore? What steps should i apply for this?

1. You don't need computers. You can do extended pings setting the source address if you need to test reach-ability.

2. What type of 1700? Not all of them support router on a stick set up.

1) could you give me an example for this? how to and where should i do extended ping?

2) both 1700 looked same as box. However, while one of them swallowed the command, the other didnt. Due to IOS version difference. How to IOS upgrade?

1. Using the Extended ping and Extended traceroute Commands - Cisco Systems

2. You are going to have to be a bit more specific. What model do you have? A lot of routers look alike.

Well, i read the description on the link. but, how does it do with the computers?

You don't do it with computers. You just ping from the router using the segment the computer would sit on as the source. When the packet is routed it will have a source address as if it were a host on that segment rather than the default behavior of using the outgoing interface address as the source.

No offense but for a CCNA you seem pretty clueless.

^ I was thinking the same.

i got that part. However, how would this do with the computers? lets say, i linked each switch with each router. But, each switch also has to be connected to the computers. When there is not enough computers(only a laptop), how would extended ping do this job?

Whose IP address could be the source address for extended ping?

Use your router as if it were a host to ping to other networks.

Agreed. OP - you're asking questions that you should already know the answer to. Either you put CCNA on your cert list or you brain dumped your way through. If the latter is the case, I suggest you take CCNA off your cert list and knuckle down.
