tunnel ttl
This command configures the TTL (Time to Live) value stored in the IPv4
header of a packet used for tunneling IPv6 traffic. Use the
no
form to
restore the default value.

- The TTL value of the IPv4 encapsulating packet.
(Range: 0-255, where zero means that the TTL value is taken from
the Hop Limit set in the IP header of the encapsulated IPv6 packet)

The command sets the hop limit for the IPv4 encapsulating packet.
However, note that IPv6 over IPv4 tunnels are modeled as a “single-hop.”
That is, the IPv6 hop limit is decremented by only one when an IPv6 packet
traverses the tunnel. The single-hop model serves to hide the existence of
a tunnel. The tunnel is opaque to users of the network, and is not
detectable by network diagnostic tools such as traceroute.
