Example: Configuring DHCP Relay in a Bridge Domain VLAN Environment
The following example configures DHCP relay in a VPLS environment to trust only the MAC addresses learned on the listed interfaces.
 | Note: This is not a complete router configuration. |

Only MAC addresses learned on the five listed Gigabit Ethernet interfaces will be trusted for DHCP relay purposes.
