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
ip auto-configure ip-subscriber
ip auto-detect ip-subscriber
ip dhcp-external server-sync
ip route
ip route-map ip-subscriber
set ip interface-profile
You can delete clients from a virtual router's DHCP binding table. You can delete all
clients or a specific client.
NOTE: This command is deprecated and might be removed completely in a
future release. The function provided by this command has been replaced
by the dhcp delete-binding command.
To delete clients from a virtual router's DHCP binding table, issue the dhcp-external
delete-binding command in Privileged Exec configuration mode:
To delete all clients:
host1#dhcp-external delete-binding all
To delete a specific client:
host1#dhcp-external delete-binding binding-id 3972819365
