To do… Use the command… Remarks
Configure the destination
address for the tunnel
interface
destination ipv6-address
Required
By default, no destination address is
configured for the tunnel.
z To encapsulate and forward IPv4 packets whose destination address does not belong to the
network segment where the receiving tunnel interface resides, you need to configure a static route
or dynamic routing for forwarding those packets through this tunnel interface. If you configure a
static route to that destination IPv4 address, specify this tunnel interface as the outbound interface,
or the peer tunnel interface as the next hop. A similar configuration needs to be performed at the
other tunnel end. If you configure dynamic routing at both ends, enable the dynamic routing
protocol on both tunnel interfaces. For the detailed configuration, refer to Static Routing
Configuration or other routing protocol configurations in the Layer 3 - IP Routing Configuration
Guide..
z Two or more tunnel interfaces using the same encapsulation protocol must have different source
and destination addresses.
z If you specify a source interface instead of a source address for the tunnel, the source address of
the tunnel is the primary IP address of the source interface.
Configuration Example
Network requirements
The two subnets Group 1 and Group 2 in the private network running IPv4 are interconnected over the
IPv6 network by using an IPv4 over IPv6 tunnel between Switch A and Switch B.
