IGP Configuration Guide.
pppoe
pppoe subinterface atm
Use to set an IP address for the interface.
Note that you cannot add more than one IP address to bridged Ethernet
interfaces.
Example
host1(config-subif)#ip address 160.1.0.1 255.255.255.0
Use the no version to remove the IP address.
See ip address.
Use to enable or disable MAC address validation on a per interface basis.
When MAC address validation is enabled, the router checks the entry in the MAC
validation table that corresponds to the IP source address of an incoming packet.
The MAC source address of the packet must match the MAC source address of
the table entry for the router to forward the packet.
Use the strict keyword to prevent transmission of IP packets that do not reside
in the validation table.
Use the loose keyword to allow IP packets to pass through even though the
packets do not have entries in the validation table. Only packets that have
matching IP–MAC pair entries in the table are validated. This is the default setting.
The default behavior is not to perform MAC address validation.
Example
host1(config-subif)#ip mac-validate strict
Use the no version to disable the command.
See ip mac-validate.
Use to create a PPPoE major interface.
Example
host1(config-subif)#pppoe
Use the no version to remove the PPPoE major interface.
See pppoe.
