Packet Tracer Help

Currently I am working on a network I have devoloped. I have two routers, one company one remote. On the company router I have 2 switches and a server connected to it. And off those switches are two department computers on each switch. I'm not sure what else I am missing and am having a difficult time. My .pkt file is attached, along with my IP addressing scheme. Im having trouble with the two switches. I'm not sure how to set up trunking, as I'm more familiar this the concept when there are three switches connected. Any assistance would be greatly appreciated.

    you are doing inter-vlan routing.

    One Problem  is with default getway of PCs are mixed up with IPs on Router sub-interfaces. f.e

    interface FastEthernet1/0.1 has ip address 172.16.15.2 but PC Sales IP is 172.16.15.2 and default gateway is 172.16.15.1.

    Change IP 172.16.15.2 to 172.16.15.1 on interface FastEthernet1/0.1

     

    basically; PCs default gateway IPs should match IPs on routers (or router sub-interfaces)

     

    Fix that for all PCs ( I think all PCs) by flipping IPs

     

    Problem 2 - 2 links between switches should be trunks (you have just one link). No big deal here.

     

    You have enabled RIP but there are no networks command statments. I did not check the other router but he will not see 172.16.15.0 networks.

    With RIP is probably good idea to run version 2 and no auto-summary.

    looks like you got RIP 2  with 172.16.0.0 on 2 routers;

    now you need add network 215.15.15.0 on each.

     

    also add no auto summary under RIP. You have class B network separated by Class C, you need no auto summary command to disable auto summarization and to avoid problems.

     

    so both routers should have something like that

    router rip

    version 2

      network 172.16.0.0

    network 215.15.15.0

    no auto-summary

    Re: Packet Tracer Help

    can you ping every PCs and Servers ? and between Vlans ?

    if Yes, you are OK; unless you want to add to it.

     

    Save your work.

    Re: Packet Tracer Help

    S2(config)#interface FastEthernet0/2

    S2(config-if)#

    S2(config-if)#switchport mode trunk

    S2(config-if)#

     

    and SW 1 has 3 Trunk ports: 1, 2 , 3
