Unable to ping behind SVI

whartigan1
Level 1
Level 1

I have one I think should be really simple but I can fix it to save my life....

Running a little Cisco 1811 router. 

Int fa0 = Outside interface to Cable Modem

Int vlan1921 = SVI for the local LAN

Everything works swimmingly on vlan 1921. No issue communicating between device or to the internet.

If I create a loopback or another SVI interface I can ping the 1921 SVI Router IP, but I cannot ping any devices behind the SVI... 

If I try to ping the router ip of another SVI or loopback from a device on the 1921 vlan it times out.

Thoughts?

RESOLVED.

In doing ping tests I somehow managed to pick the ONLY two devices in my entire house that are not responding to pings across the SVI's. I have since tested other IP's and can successfully route between SVI's. 

Issue to be troubleshooted local to each device that won't respond... Go figure its my FTP/TFTP server I can't reach of all things...
