Hi, I recently configured a GRE tunnel between two networks. On one of two sides of the tunnel I have a router with a public IP which refreshes from time to time or when it reboots. I configured the other side of the tunnel with the command tunnel destination "hostname". I noticed that during the configuration, the hostname is resolved and what it is actually configured is the IP. So everytime the public IP is refreshed, the tunnel is closed because the tunnel destination address is wrong.
What is the ideal solution for this problem?
Thank you!
