C H A P T E R 1 0 IP Unicast Routing
For example, an IP host is configured with a class B address of
100.101.102.103 and a mask of 255.255.0.0. The switch is
configured with the IP address 100.101.102.1 and a mask of
255.255.255.0. The switch is also configured with a proxy ARP
entry of IP address 100.101.0.0 and mask 255.255.0.0,
without the
always
parameter.
When the IP host tries to communicate with the host at address
100.101.45.67, the IP hosts communicates as if the two hosts are on
the same subnet, and sends out an IP ARP request. The switch
answers on behalf of the device at address 100.101.45.67, using its
own MAC address. All subsequent data packets from
100.101.102.103 are sent to the switch, and the switch routes the
packets to 100.101.45.67.
Relative Route Priorities
Table 42 lists the relative priorities assigned to routes depending
upon the learned source of the route. Although these priorities can
be changed, do not attempt any manipulation unless you are
expertly familiar with the possible consequences.
