Deleting Clients from a Virtual Router's DHCP Binding Table

Use the exclude-primary keyword in the ip auto-configure ip-subscriber
command to specify that the primary interface cannot be assigned to a subscriber.
If you have issued the ip dhcp-external server-sync command to resynchronize
the DHCP external server application with the router and to support creation of
subscriber state information based on lease renewals, you must do either of the
following to ensure that the unicast acknowledgment (ACK) response to the
renewal request has a route back to the DHCP client that generated the renewal
request:
Enable the packet detection feature on the static primary IP interface in the
context of the VR in which the static primary interface resides.
host1:relay(config-if)#ip auto-detect ip-subscriber
Issuing the ip auto-detect ip-subscriber command creates a dynamic
subscriber interface back to the DHCP client when the router receives a
packet with a source IP address that does not match any entries in the
demultiplexer table. This method requires you to configure the primary IP
interface to support creation of dynamic subscribers interfaces, which is
accomplished by issuing the ip auto-configure ip-subscriber
exclude-primary command, as shown in Step 4.
Configure an explicit network route in the context of the VR in which the
static primary interface resides to provide connectivity back to the DHCP
client.
host1:relay(config)#ip route 71.23.0.0/24 fastEthernet 5/5.100
