The following sample conguration shows a tunnel congured in IPIP mode (IPv4 tunnel carries IPv4 and IPv6 trac):
Dell(conf)#interface tunnel 3
Dell(conf-if-tu-3)#tunnel source 5::5
Dell(conf-if-tu-3)#tunnel destination 8::9
Dell(conf-if-tu-3)#tunnel mode ipv6
Dell(conf-if-tu-3)#ip address 3.1.1.1/24
Dell(conf-if-tu-3)#ipv6 address 3::1/64
Dell(conf-if-tu-3)#no shutdown
Dell(conf-if-tu-3)#show config
!
interface Tunnel 3
ip address 3.1.1.1/24
ipv6 address 3::1/64
tunnel destination 8::9
tunnel source 5::5

Conguring Tunnel Keepalive Settings
You can congure a tunnel keepalive target, keepalive interval, and attempts.
NOTE
: By default, the tunnel keepalive is disabled.
The following sample conguration shows how to use the tunnel keepalive command.
Dell(conf-if-gi-1/12)#show config
!
interface GigabitEthernet 1/12
ip address 40.1.1.1/24
ipv6 address 500:10::1/64
no shutdown
Dell(conf-if-gi-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

Conguring a Tunnel Interface
You can congure the tunnel interface using the ip unnumbered and ipv6 unnumbered commands.
To congure the tunnel interface to operate without a unique explicit IP or IPv6 address, select the interface from which the tunnel borrows
its address.
