I have an interesting issue occurring. One of the sites connected to our DMVPN has been exceedingly flakey today. A continuous ping to the spoke router shows intermittent time outs, however a continuous ping to the outside interface of the ASA onsite is fine.
I notice the TTL values on the ping to the ASA are constantly changing from 239 to 240. Could this be what is causing the issue? If so i'd love to know why this is occurring.
Just FYI, the spoke hasn't had any previous issues and has been running more or less without issue for the past 2 years. No other sites on the same DMVPN are experiencing any issues either.
