Due to a recent merger, we're faced with setting up a site-to-site tunnel between a Cisco device and Juniper device. We get the tunnel up but it doesn't stay up reliably. It drops without apparent reason and it's been impossible thus far to determine the cause. The Cisco logs merely show a timeout and thus far, I've been unable to locate anything in the Juniper logs (still new to it so I haven't gotten far there yet). Thus I have little to go on. But while I'm searching (and pulling my hair out), I thought I'd run it by the experts to see if anyone had a similar problem just in case..... Attached are the config files for review.
Thank you and perhaps you can save what's left of my hair.
