[zebra 22981] Re: Configuring RIP

Dear Mr Campbell,

            Thanks a Lot. Whatever you suggested , I tried with that and
     it worked fine. 
 
    That is the true spirit of open source . I queried yesterday , the same day I 
    got reply and it is working the next day.

    Once again , thanks and thanks a lot to Zebra.

Even if  you share RIP routes they will not be able to communicate because they don't  have  a router to move packets from the two seperate subnets.  ie. if  you are trying to move packets from an interface in one subnet to a completely  seperate subnet on another machine you will 1) have to use a router to move the  packets between the seperate subnets or 2) both interfaces will have to be in  the same subnet.  If both devices are in the same Layer 2 network then it  is expected that they will either have a common subnet and simply arp for each  other.  Otherwise if they are in two seperate subnets then it is expected  that there will have to be a router somewhere (even in the same L2 network) to  get the packets moving.  This is because the way IP work
 s if you are not in  the same subnet then you will pass packets for any "remote" network
 to a IP  routing device.
  
 If you  are trying to practive routing what you need to do is add another NIC to each of  the machines.  Then recreate your scenario by connecting an interface on  each box into the same Layer 2 network and put then in the same subnet.   Then run RIP on that interface and test ping the subnets on the other  interfaces. 
  
 eg.
  
 192.168.0.0/24  <----------> Machine1  <----------> 10.1.1.1/30  ===RIP=== 10.1.1.2/30  <----------> Machine2 <----------> 172.16.0.0/16
  
 Because there are no other routers involved the  machines have to share a common Layer 3 interface to route packets between  your netowrks
  
 Hope  this helps.

Subject: [zebra 22979]    Configuring RIP


Hi    All,

      I am new to zebra and also new to    routers.
      So , I am just experimenting with    zebra.

      What I have done is connected    two  desktop machines with Fedora Core    6
      as the OS and connected both the machines    to the  same switch.

      The machine    description are as follows.

      Machine    1

      1. ip     :    192.168.0.254
      2. mask   :    255.255.255.0
      3. Gateway:    192.168.0.254
  
      Machine    2
 
      1. ip       :172.16.16.1
      2. mask     :255.255.0.0
      3. Gateway :    172.16.16.1

      Now using zebra,I configured    the interface on machine 1 as the same information as      
      provided below. I did the same with    machine 2 with ip shown above
         
      After I configured RIP on Machine 1 ,    and tried the following    commands.
                 1. router    rip
                 2. network    192.168.0.0/32
                 3. network    eth0
                 4. redistribute    connected
                 5. redistribute    kernel
                 6. write memory

     On Machine 2, I tried the same    commands and advertised the network 172.16.0.0/16    


     But the problem is that after    distributing the routes from both the machine, I am still    
     not able to ping each other    .
     If I do    ,
                 show ip route on machine 2 , it is as    follows
              
        Network                      Next Hop         Metric      From               Time
     C(i)    172.16.0.0/16           0.0.0.0                1     self
          
      It is not showing any RIP    routes.
 
      Please help me in    configuring rip correctly.
