Greetings-
I'm have an issue with and EIGRP configuration. I know I'm missing something obvious but too wrapped up to see what it is. I have a site with DMVPN tunnels back to 2 hubs, (I only care about one tunnel,100, if it works the other should). I'm getting one network advertised to the hub, but can't see the other, and I can ping some of the devices on the second network, (the one that works), but not all.
10.87.32.0/21 works fine advertising to hub
10.87.40.0/21 can ping some, but not all devices, no route advertisements on core
I also tried changing the summary address to 10.87.32.0/20 and that did not help, (it did show up as 32/0 on core but still had issues routing to high range on site). Believe I also tried adding a loopback on the 10.87.40.0/21 and could see it, (as well as some other specific devices on that network), but not the network route
If anyone has a moment to look I'd appreciate it, and have attached the relevant parts of the config, (I think). I'm hoping I'll either come up with a quick answer myself, or will just resort to banging my head against the wall......some details below, attaching relevant portions of config as well. Thanks,

Hello,
is the below from the running config ? Your Tunnel100 is 'shutdown', is that supposed to be that way ?

Hi,
Thanks for looking---it's right "for now", this was for a hot-cut to a new router/circuit. The tunnel was up and working fine, I had to shut it down when I backed out the changes and copied the config after that.
