    Ok, ive been letting the routers sit for ahwhile, while i do my studys, but seems the is a problem now.. I can ping the eth int on router a, and i can
    ping the serial interface on router A, but when i try to ping serial int on B, through A, i get a time out.. So i try to ping it from router A it pings perfect, but if i try to do eth int on B from A, Nada. I did a show running-config on both and they seem to be good to me.. Any ideas?

    BTW, when i added routes to my computers, i didnt -p them, so that was what i was originally doing..

    Sounds like a routing problem, did you add all the networks with the network command? Does sh ip ro (show ip route) on routerA show routes to the networks of routerB?
  • pandimuspandimus Member Posts: 651
    When i do a sh ip ro on each router, it only shows the first connection on the opposite router i/e serial 1. I does not show anything on the other router beyond that..

    Oh, i'm pretty sure i added all the networks like your techlab said.

    Please post the interfaces and router rip config of both routers and the show ip route ouput (the routes alone will suffice).

    The network command is used to define the local network, directly attached to the router. Try the following:

    RouterA(config)# router rip
    RouterA(config-router)# no network 192.168.33.0
    RouterA(config-router)# no network 192.169.11.0
    RouterA(config-router)# no timers basic
    ctrl-z and wr ;)

    RouterB(config)# router rip
    RouterB(config-router)# no network 192.168.11.0
    remove timer adjustments if any, ctrl-z and save

    RouterA# clear ip route *
    RouterB# clear ip route *

    Wait a sec and then try again and check if both routers have a route to the far-end ethernet network.

    Exactly. :D

    Does it work from the multi-homed pc also?
  • pandimuspandimus Member Posts: 651
    Well... I am attempting router A to play this same game.. cant seem to get it to ping the other router.

    hmmm, it is still not learning RIP routes. Did you run the clear ip route * command on routerA as well?
  • pandimuspandimus Member Posts: 651
    yes sir

    Is the Ethernet0 interface on routerB in network 192.168.33.0/24 up?

    And the setup is like this:

    Right now I can only suggest going thru both configs again, cause it is weird routerB is learnign RIP routes from routerA but not vice versa.

    If you still have that tftp server running, copy the configs to it, and send them to my email address and I'll have a look. (copy running-config flash) I have pretty much the same config in my lab.
  • pandimuspandimus Member Posts: 651
    i can only get the config from router A, cause i cant telnet into B cause of this problem

  • pandimuspandimus Member Posts: 651
    Actually this is what i get when doing that from Router A

    Do you think the router could be bad?

    icon_redface.gif Sorry about that, I meant copy run tftp not to flash.

    NP you got mail.

    Thanks for your help..

  • WebmasterWebmaster Admin Posts: 10,292 Admin
    Try this:

    RouterA(config)# router rip
    RouterA(config-router)# no timers basic


    RouterB(config)# router rip
    RouterB(config-router)# version 2

    and then clear ip route * on both routers
  • pandimuspandimus Member Posts: 651
    Did i forget to enable version to on router A? icon_redface.gif

    i originally had router b with no timers,(after you said it, then i enabled them in troubleshooting..)

    your a lifesaver..

  • WebmasterWebmaster Admin Posts: 10,292 Admin
    My pleasure :)

    RIP defaults to sending only version 1 packets, but listens to both version 1 and 2. That's why it did accept the routes from the other routerB that is configured to send and receive rip2 only.
  • pandimuspandimus Member Posts: 651
    Sometimes i can be such a dummy.. Well i found one other thing in this situation.. Seems ser 0 on router A is hot.. So if there is a problem with a serial port it may be on router B.. Or i could of just royally messed it up when setting it up..

  • pandimuspandimus Member Posts: 651
    So everything seems to be working..

    I am now using the virtual switch manager to configure my switch.. ITs cool.. you can setup hello time for STP.. max age.. Blocking forwarding.. enable disable. Gotta love it.. I NEED another switch to mess with trunking!!!

    Is there any difference b/w the back to back seriel cable ie two cables or using one complete db60 cable ? icon_redface.gif
  • WebmasterWebmaster Admin Posts: 10,292 Admin
    As long as it's a V.35 cable, no.

    The reason some go for the 'two cables' is that one is often included with the router. I guess for a homelab you should go the most affordable way, which is the back-to back cable.

    I have been looking over these forums for a long time, used the Net+ notes and have passed my A+ and Net+ due to a lot of info from this site. Thanks Webmaster!!

    My Question: I'm attending a CCNA class at University of Central Florida, we have a lab which I have 24/7 access to but it is a pain to get to (due to work, classes and reserved times so everyone has access). The lab has 2 2501 routers, 1 1601, 1 2610, another 2500 series (acts as frame relay so we never do anything else with it) a series 400 fast hub, and a 1900 switch.

    Do to my time restrictions I have deccided to buy my own equipment.

    Off Ebay, I've purchased 1x 2513 Router (IOS 11.x), 3x 2501 Routers (IOS 12.2), a Catalyst 1900 switch (12 10MB ports with 2 100MB ports), all inclusive for $245 shipped to my door. Cables have been alittle extra, and I'm still looking for 3 more aui transceivers. I am worried about VLAN's and what I will need. At school we use 2610 router, hub and switch (or so I'm told, haven't gotten that far yet). I have been looking for a Catalyst 2900 series (a 2926-xl was recommended in the CCNP forums on this site, would any 2900 do?) and a 2600 router, which will also allow me to use them for my CCNP.

    Am I going overboard? I am definately a hands on type of person, and if the 2600 series router and the 2900 switch will give me the experience I need, I am willing to go for it. I was jsut looking for some advice.

    Thanks
