I have a 2610 with IP 10.10.120.1 router and 3550 series switch. I have configured Vlan on 3550
ip address 10.10.120.10 255.255.255.240)
and i have configured port f0/4 with IP (IP block 10.10.121.188/30)
ip address 10.10.121.189 255.255.255.252
no ip route-cache)
also given default route -
ip route 0.0.0.0 0.0.0.0 10.10.120.1
but when i am connecting laptop with IP 10.10.121.190/30 to 3550 i am not able to ping 10.10.120.1
but if i ping it from 3550 i am able to ping.
on 2610 i have routed - ip route 10.10.121.188 255.255.255.252 10.10.120.10
Please help. what more config i required to connect 2610 with 3550
yes it is 10.10.121.189
from 2610 router i am able to ping 10.10.120.1 but not able to ping 10.10.121.189. Means my connectivity is not ok. i have routed the route on 2610
Not able to find solution.
we need more config info. please post what you can.
from what i see the configuration is not completed.
i do not see what port the 2610 connects to the 3550 with.
i do not see a trunk to the 3550 from the 2610 if the link is to carry multiple vlan traffic.
it looks as if your 2610 is configured for 10.10.120.0/29 only. how does the router know of 10.10.121.188/30 ? i dont see the proper routes or direct connections for the router to communicate with 10.10.121.188/30.

post your config and we can tell you what to add, remove or whatever else may be needed.
Your configuration looks good. Can you check the IP configuration on your laptop and there could easily be a typo like, instead of typing the gateway as 10.10.121.189 you could have plugged in 10.10.121.89
If you don't find anything wrong with the laptop configuration then proceed with the following troubleshooting.
1. Ping the 10.10.121.89 from the laptop. If it doesn't work then you have a physical layer problem or ip configuration error. If this works go to step2.
2. Ping 10.10.120.10 from the laptop. If it doesn't work then there's a IP configuration error on the laptop or switch. If this works then go to step3.
3. Ping 10.10.120.1 from the laptop. If it doesn't work then the problem is with configuration on the router as you already stated you are able to ping the router from the switch.
Hope that helps!
I don't see any 'ip routing' command in the 3550.
If you issue 'show ip route', do you see any routing table on the 3550 ?
Please rate helpful posts.
I read the question and wanted to know why is it that you have assigned the port an IP address. We do not wish to do any routing on the switch so please let the port be a L2 port. The switch port can be changed to L2 port by using the command "switchport". After this set the DG oln your laptop to the IP address 10.10.120.10 and you should be good to go from thereon.
Hope this helps !!!
i want to connect IP base modem to 3550 switch. That's why i am testing this scenario.
But not getting the connectivity through.
My down path will be 2610 to 3550 to my Modem and up path Vise-versa
hi guys thanks for the help, i got my mistake, its rectify now... i have not enabled "ip routing" command on 35550 switch .
Thank's for the support.
In this case too you need not make the port on the 3550 as a L3 port. You can assign an IP address to your Router interface and the switch SVI that you want to use and do a No shut on that interrace and all the devices in that SVI will get the connectivity.
