Description:
vRtrIfDHCPAutoFilter allows the router to automatically build anti-spoofing filter lists. When this object is set to a non-zero value, auto-filtering is enabled and a filter allowing only PPPoE or DHCP traffic is established on the interface. The non-zero value indicates the maximum number of entries that the auto-filter can have. These entries are created by the agent upon snooping a valid DHCP Reply packet and are used to allow traffic sourced by the given DHCP-assigned IP address.
What is vRtrIfDHCPAutoFilter?
Controls whether the router automatically builds anti-spoofing filter lists on the interface based on DHCP or PPPoE session data. When set to a non-zero value, a filter permitting only PPPoE or DHCP traffic is created, helping prevent IP address spoofing.
