Tunneling
Tunneling is supported on the Z9000 platform.
Tunneling supports RFC 2003, RFC 2473, and 4213. DSCP, hop-limits, flow label values, OSPFv2, and OSPFv3 are also
supported. ICMP error relay, PATH MTU transmission, and fragmented packets are not supported.
Configuring a Tunnel
Configuring a tunnel is supported on the Z9000 platform.
You can configure a tunnel in IPv6 mode, IPv6IP mode, and IPIP mode.
• If the tunnel mode is IPIP or IPv6IP, the tunnel source address and the tunnel destination address must be an
IPv4 address.
• If the tunnel mode is IPv6, the tunnel source address and the tunnel destination address must be an IPv6
address.
• If the tunnel mode is IPv6 or IPIP, you can use either an IPv6 address or an IPv4 address for the logical address
of the tunnel, but in IPv6IP mode, the logical address must be an IPv6 address.
. The following sample configuration shows a tunnel configured in IPv6 mode (carries IPv6 and IPv4 traffic).
FTOS(conf-if-fo-0/84)#ipv6 address 2adb::3/64
FTOS(conf-if-fo-0/84)#ip address 23.22.22.3/24
FTOS(conf-if-fo-0/84)#int tun 23
FTOS(conf-if-tu-23)#no shut

FTOS(conf-if-tu-23)#ipv6 address 3adb::3/64
FTOS(conf-if-tu-23)#
FTOS(conf-if-tu-23)#
FTOS(conf-if-tu-23)#
FTOS(conf-if-tu-23)#exit
FTOS(conf)#ipv6 route 1adb::/64 2adb::2
FTOS(conf)#Apr 19 09:59:54: %STKUNIT0-M:CP %IFMGR-5-OSTATE_UP: Changed
interface state to up: Tu 23
The following sample configuration shows a tunnel configured in IPV6IP mode (IPv4 tunnel carries IPv6 traffic only):
FTOS(conf-if-tu-22)#sho c
!
interface Tunnel 22
no ip address
