RIP Entries

[Wasantha]

Hi Guyz,

I have configured RIPv2 in a router on PT, When i execute show ip route command ,the routing table shows  two exit interfaces to same destination. How could i solve this. Please Help me...  I have attached Screen shot with this..

Here are two options. The first is using an "offset-list" which will raise or lower the metric in this case hop count and make the route less desirable from one of the interfaces. The second is a "distribute-list" where you could filter the route from one of the interfaces. 

offset-list {access-list-number | access-list-name} {in | out} offset [interface-type interface-number]

distribute-list {access-list-number | prefix prefix-list-name [gateway prefix-list-name]} in [interface-type interface-number]

One other option is the "maximum-paths" command. You can set this to "1" under the routing process and it will only accept one path per route.

Hi Troy,
Is this all Commands works in Packet Tracer.?

Hi Troy,

Thanx for your help. could you please tell me how to execute that command. I mean please can give me example. 

Thank You.

Sorry for the delay. The above commands are not only Packet Tracer commands they are RIP commands. Here is an example below:

(If we want to add to the hop count from a neighbor's routes in on S0/1/0)

1. Create an ACL

access-list 1 permit 172.16.2.80 0.0.0.3

2. Add the "offset list" to the RIP process

router rip

version 2

network 172.16.0.0

offset-list 1 in 5 Serial 0/1/0  <---- **This will add 5 hops to the count coming in on S0/1/0**

3. The route will now show in one direction "S0/0/1".
