Usage Information Enabling tunnel keepalive causes ICMP echo packets to be sent to the keepalive
target. The ICMP echo will be sourced from the tunnel interface logical IPv4 or IPv6
address and will be tunnel encapsulated. The response will be accepted whether it
returns tunnel encapsulated or not.
When configuring tunnel keepalive at both end points of a tunnel interface it is
recommended to set the tunnel keepalive target to the logical IPv4 or IPv6 address of
the far end tunnel peer, rather than to the tunnel destination. This reduces the chance
of both ends of the tunnel staying in keepalive down state. If both ends get into a
keepalive down state that does not clear in a few seconds, then performing shutdown -
no shutdown sequence on one end should bring both ends back to up.
