Advertising Subnets Assigned To Clients - HPE FlexNetwork HSR6800 Configuration Manual

If the address pool is applied to a VPN instance, the VPN instance must exist.
To bind the gateways to the DHCP server's MAC address:
Step

2. Create a DHCP address pool
and enter its view.
3. Bind the gateways to the

Advertising subnets assigned to clients

This feature enables the route management module to advertise subnets assigned to DHCP clients.
This feature achieves symmetric routing for traffic of the same host.
As shown in
The BRAS devices send accounting packets to the RADIUS server. To enable the BRAS devices to
collect correct accounting information for each RADIUS user, configure the DHCP server to
advertise subnets assigned to clients. The upstream and downstream traffic of a RADIUS user will
pass through the same BRAS device.
