interface Tunnel 2
no ip address
ipv6 address 2::1/64
tunnel destination 90.1.1.1
tunnel source 60.1.1.1
tunnel mode ipv6ip
no shutdown
The following sample conguration shows a tunnel congured in IPIP mode (IPv4 tunnel carries IPv4 and IPv6 trac):
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
!

tunnel mode ipv6
no shutdown
Conguring Tunnel Keepalive Settings
You can congure a tunnel keepalive target, keepalive interval, and attempts.
NOTE
: By default the tunnel keepalive is disabled.
The following sample conguration shows how to use tunnel keepalive command.
Conguring a Tunnel Interface
You can congure the tunnel interface using the ip unnumbered and ipv6 unnumbered commands.
To congure the tunnel interface to operate without a unique explicit ip or ipv6 address, select the interface from which the tunnel will
borrow its address.
The following sample conguration shows how to use the tunnel interface conguration commands.
