Network requirement
There are two egresses of a LAN connecting to the Internet. In general, load
balance and backup should be enabled for these two egresses. All streams from
subnet 1 to the Internet are transmitted through GigabitEthernet 0/1 and all
streams from subnet 2 to the Internet are transmitted through GigabitEthernet 0/2.
If GigabitEthernet 0/1 is disconnected, the data streams on this interface should
be transferred to GigabitEthernet 0/2, and vice versa.
Network topology
As shown in Figure 2, Device1 connects to subnets 1 and 2 through G0/3 (routed
port), and connects to the Internet through G0/1 and G0/2 with the next hop of
2001::1/64 and 2002::1/64, respectively. Subnet 1’s segment is 2003::/64 and
subnet 2’s segment is 2004::/64.
