tunnel mode ipv6ip
no shutdown
The following sample configuration shows a tunnel configured in IPIP mode (IPv4 tunnel carries IPv4 and IPv6 traffic):
DellEMC(conf)#interface tunnel 3
DellEMC(conf-if-tu-3)#tunnel source 5::5
DellEMC(conf-if-tu-3)#tunnel destination 8::9
DellEMC(conf-if-tu-3)#tunnel mode ipv6
DellEMC(conf-if-tu-3)#ip address 3.1.1.1/24
DellEMC(conf-if-tu-3)#ipv6 address 3::1/64
DellEMC(conf-if-tu-3)#no shutdown
DellEMC(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 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.
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.
The following sample configuration shows how to use the interface tunnel configuration commands.
Configuring Tunnel Allow-Remote Decapsulation
You can configure an IPv4 or IPV6 address or prefix whose tunneled packet is accepted for decapsulation.
If you do not configure allow-remote entries, tunneled packets from any remote peer address are accepted.
You can configure up to eight allow-remote entries on any particular multipoint receive-only tunnel.
The following sample configuration shows how to configure a tunnel allow-remote address.
DellEMC(conf)#interface tunnel 1
DellEMC(conf-if-tu-1)#ipv6 address 1abd::1/64
DellEMC(conf-if-tu-1)#ip address 1.1.1.1/24
DellEMC(conf-if-tu-1)#tunnel source 40.1.1.1
DellEMC(conf-if-tu-1)#tunnel mode ipip decapsulate-any
DellEMC(conf-if-tu-1)#tunnel allow-remote 40.1.1.2
DellEMC(conf-if-tu-1)#no shutdown
DellEMC(conf-if-tu-1)#show config
!
