About Keep-Alive Settings
The tunnel keepalive mechanism enables, extends, and implements an interface-specific
command for tunnel interfaces, and provides the ability to bring down the line protocol of a
tunnel. The tunnel keepalive mechanism also addresses these additional requirements:
• The tunnel keepalive mechanism functions even if the far tunnel endpoint does not support
keepalives.
• The tunnel keepalive mechanism originates keepalives.
• The tunnel keepalive mechanism processes keepalives.
• The tunnel keepalive mechanism replies to keepalive packets of the far end, even when the
line protocol of the tunnel is down.
