Chapter 3 Tunneling Configuration
3-13
Caution:
z
Only one tunnel can automatically be configured at the same tunnel source.
z
No destination address needs to be configured for an automatic IPv4-compatible
IPv6 tunnel.
z
If the addresses of the tunnel interfaces at the two ends of a tunnel are not in the
same network segment, a forwarding route through the tunnel to the peer must be
configured so that the encapsulated packet can be forwarded normally. You can
configure static or dynamic routes. For the detailed configuration, refer to “IPv4
Routing” or “IPv6 Routing” module.
z
When you configure a static route, you need to configure a route to the destination
address (the destination IP address of the packet, instead of the IPv4 address of the
tunnel destination) and set the next-hop to the tunnel interface number or network
address at the local end of the tunnel. Such a route must be configured at both ends
of the tunnel.
z
Before referencing a link aggregation group on the tunnel interface to receive and
send packets, make sure that the aggregation group has been configured.
Otherwise, the tunnel interface will not be up to communicate.
3.4.3 Configuration Example
I. Network requirements
Between SwitchA and SwitchB is an IPv4 network. It is required that an IPv6
connection be established through an automatic IPv4-compatible IPv6 tunnel between
the two dual-stack routers.
