Configuring Tunnel Keepalive Settings

You can configure a tunnel keepalive target, keepalive interval, and attempts.
NOTE: By default, the tunnel keepalive is disabled.
The following sample configuration shows how to use the tunnel keepalive command.
Dell(conf-if-te-1/12)#show config
!
interface TenGigabitEthernet 1/12
ip address 40.1.1.1/24
ipv6 address 500:10::1/64
no shutdown
Dell(conf-if-te-1/12)#
Dell(conf)#interface tunnel 1
Dell(conf-if-tu-1)#ipv6 address 1abd::1/64
Dell(conf-if-tu-1)#ip address 1.1.1.1/24
Dell(conf-if-tu-1)#tunnel source 40.1.1.1
Dell(conf-if-tu-1)#tunnel destination 40.1.1.2
Dell(conf-if-tu-1)#tunnel mode ipip
Dell(conf-if-tu-1)#no shutdown
Dell(conf-if-tu-1)#tunnel keepalive 1.1.1.2 attempts 4 interval 6
Dell(conf-if-tu-1)#show config
!
interface Tunnel 1

Configuring a Tunnel Interface

You can configure the tunnel interface using the ip unnumbered and ipv6 unnumbered commands.
To configure the tunnel interface to operate without a unique explicit IP or IPv6 address, select the interface from which the tunnel borrows
its address.
