Adds and deletes routing table entries.
|
|
|
|
The Routes() function adds a route to or deletes a route from the routing table.
|
|
Routes are determined by comparing the SubnetAddress with the destination IP
|
|
address and arithmetically AND-ing it with the SubnetMask. The gateway address
|
|
must be on the same subnet as the configured station address.
|
|
The default route is added with SubnetAddress and SubnetMask both set to 0.0.0.0.
|
|
The default route matches all destination IP addresses that do not match any
|
|
other routes.
|
|
A zero GatewayAddress is a nonroute. Packets are sent to the destination IP
|
|
address if it can be found in the Address Resolution Protocol (ARP) cache or
|
|
on the local subnet. One automatic nonroute entry will be inserted into the
|
|
routing table for outgoing packets that are addressed to a local subnet
|
|
(gateway address of 0.0.0.0).
|
|
Each instance of the EFI UDPv4 Protocol has its own independent routing table.
|
|
Instances of the EFI UDPv4 Protocol that use the default IP address will also
|
|
have copies of the routing table provided by the EFI_IP4_CONFIG_PROTOCOL. These
|
|
copies will be updated automatically whenever the IP driver reconfigures its

instances; as a result, the previous modification to these copies will be lost.
