ANY answers why I can get some pings to work not others only on the secondary subnet

Thank you for any help you may provide.
 
Where are you sending the ping from. If its from the router then by default its uses the primary IP address as its source IP address. Therefore a device on the secondary subnet may not know how to get back to that source address.

Try with extended ping, use the secondary address as the source IP.
 
If thats the case is there any way to make the secondary IP
on the server that is being added report back to the primary subnet?????

I am setting this up

64.132.148.49 255.255.255.240 Primary
64.132.148.93 255.255.255.224 Secondary

System 64.132.148.73 255.255.255.224
DG .93
It will not answer a ping from the router and I need it to get to the primary subnet

Thanks for any help.
 
I am sorry, I do not understand the problem. Which device do you have problems reaching? As mentioned in a previous post you should use extended PING from the router if you want to PING the server. What operating system are you running on the server? Could you not assign addresses from both subnets on the server?

I am trying to setup a server.

Primary 64.132.148.49 255.255.255.240
Secondary 64.132.148.93 255.255.255.224

server is 64.132.148.73 255.255.255.224

Default gateway is 64.132.148.93

When I ping from server no answer when ip ping from router no answer.
I have not done an exstended ping how is it done???
How can I get this server to route through my router????
Thank you for any help that you may provide.

I've just looked at my PC, Win98 to see what command format an extended ping takes, and its not a supported feature.
I looked at PING /?

However from the router you can do this, just enter `ping' then return, the router will prompt you for the additional details. When asked for extended options select Y and give the source IP address you are to use. It has to be one the exists on the router.

Going back to the original problem, you should be able to ping from one server to another across the router, the problems with secondary addresses occur when pinging from or to the actual router addresses.
 
I now know how to do extended pings still the same results.
how do I get server with the IP of

64.132.148.73 255.255.255.224
Default gateway 64.132.148.93

to route through my router?????????? and see it.

Please note this is the second subnet address ????
Have this route through a router that has primary and secondary subneting on it.
Primary works just fine.
Secondary will not
any help please I have been on this for two weeks
Just a note Cisco has not given me an answer ether.
Need to talk to a master networker or someone that is very knowlagble in routeing with cisco.
please there must be a guru out there???????

FIXED FIXED FIXED
finnaly fixed the access-list group 13 needed to have every IP in it that you are going to use in the subnet.
Give it a permit and it worked.
Thanks.
