Remove as much of the rot as you can, then treat the inside of the hole with a fungicide (most rot is caused by fungus). After this, cover the hole with a metal flap to keep water and animals out. Do not fill the hole in as this can cause the fungus that is causing the rot to be trapped in the hole and the hole will continue to rot.

Every 6 months or so, check under the flap for more rot. Treat the hole with fungicide at each check.
