Relative Route Priorities
ExtremeWare XOS 10.1 Concepts Guide 179
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 35 lists the relative priorities assigned to routes depending upon the learned source of the route.
NOTE
Although these priorities can be changed, do not attempt any manipulation unless you are expertly
familiar with the possible consequences.
To change the relative route priority, use the following command:
configure iproute priority [rip | blackhole | direct | bootp | icmp | static |
ospf-intra | ospf-inter | ospf-as-external | ospf-extern1 | ospf-extern2] <priority>
Configuring IP Unicast Routing
This section describes the commands associated with configuring IP unicast routing on the switch. To
configure routing:
1 Create and configure two or more VLANs.
2
Assign each VLAN that will be using routing an IP address using the following command:
