What difficulty did you encounter with the adjust-mss command? &nbsp;I've used it extensively, and once an appropriate value is found, I've never had to remove it.<br />

Hi Expert currently office is using DMVPN tunnels. With 2800 routers at remote office. often remote office stop reach the internet and we would have to tweak config on tunnel using ip tcp adjust-mss and at times it would work but at times we would have to remove the ip tcp adjust-mss from remote routers for the office to once again work after it stops. please advise how to correct <br />

Help with MTU issue using DMVPN

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
