Once the
The DSL and/or Ethernet interface(s) are reconfigured.
Routes associated with any interfaces that have been removed are deleted. An exception to this is when the negotiated IP address is assigned to the Ethernet interface and the subnet defined by the interface’s IP address is the same as the one defined by the negotiated IP address.
All dynamic ARP entries are removed. All static ARP entries associated with the DSL interface and any removed interfaces are deleted. Static ARP entries for the Ethernet interface are retained if the negotiated IP address is assigned to the Ethernet interface and the subnet defined by the interface’s IP address is the same as the one defined by the negotiated IP address.
The negotiated IP address automatically becomes the primary IP address and the NAPT public IP address.
An active service domain Telnet session is terminated if the interface associated with the session is removed or the IP address of the interface is changing.
All DHCP bindings and BOOTP Relay Agent snoop information are removed if the subnet defined by the Ethernet IP address changes. If the new Ethernet IP address is still in the same subnet, then only the binding and snoop information that conflicts with this IP address is removed.
