31.3.2 DHCPv6 Relay option37, 38 Example
Example 1:
When deploying IPv6 campus network, DHCPv6 server function of routing device can be used
for IPv6 address allocation if special server is used for uniform allocation and management for
IPv6 address. DHCPv6 server supports both stateful and stateless DHCPv6.
Network topology:
In access layer, layer2 access device Switch1 connects users in dormitory; in first-level
aggregation layer, aggregation device Switch2 is used as DHCPv6 relay agent; in second-level
aggregation layer, aggregation device Switch3 is used as DHCPv6 server and connects with
backbone network or devices in higher aggregation layer; in user side, PCs are generally
loaded with Windows Vista system, thus having DHCPv6 client.
