The following sample configuration shows a tunnel configured in IPIP mode (IPv4 tunnel carries IPv4 and IPv6 traffic):
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
tunnel mode ipv6
no shutdown
Configuring Tunnel keepalive
Configure the tunnel keepalive target, interval and attempts.
By default the tunnel keepalive is disabled.
The following sample configuration shows tunnel keepalive command:
Dell(conf-if-te-0/12)#show config
!
interface TenGigabitEthernet 0/12
ip address 40.1.1.1/24
ipv6 address 500:10::1/64
no shutdown
Dell(conf-if-te-0/12)#
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
ip address 1.1.1.1/24
ipv6 address 1abd::1/64
tunnel destination 40.1.1.2
tunnel source 40.1.1.1
tunnel keepalive 1.1.1.2 attempts 4 interval 6
tunnel mode ipip
no shutdown
Configuring the ip and ipv6 unnumbered
Dell Networking OS supports configuring the tunnel interface.
You can configure the tunnel in ip unnumbered and ipv6 unnumbered command. To configure the tunnel interface to operate
without a unique explicit ip/ ipv6 address, select the interface from which the tunnel will borrow its address.
The following sample configuration shows the IP unnumbered command:
Dell(conf-if-te-0/0)#show config
!
interface TenGigabitEthernet 0/0
