Tunnel Configuration Examples

ExtremeWare XOS supports two types of tunnels, IPv6-in-IPv4 tunnels (known as configured tunnels or
6in4 tunnels) and IPv6-to-IPv4 tunnels (known as 6to4 tunnels). Both types of tunnels can be used to
connect regions of IPv6 routing across a region of IPv4 routing. From the perspective of the router, the
tunnel across the IPv4 region is one hop, even if multiple IPv4 routers are traversed during transport.
A 6in4 tunnel connects one IPv6 region to one other IPv6 region. Multiple 6in4 tunnels can be
configured on a single router to connect with other IPv6 regions. Dynamic and static routing can be
configured across a 6in4 tunnel. Hosts in the IPv6 regions need know nothing about the configured
tunnel, since packets destined for remote regions are sent over the tunnel like any other type of routing
interface.
A 6to4 tunnel connects one IPv6 region with multiple IPv6 regions. Only one 6to4 tunnel can be
configured on a single router. Hosts in the IPv6 regions connected by 6to4 tunnels must be configured
with 2002::/16 6to4 addresses in order for traffic to flow. ExtremeWare XOS does not support 6to4 relay
router functionality.
