DXS-3326GSR Gigabit Layer 3 Switch
OSPF ExtT2 (1-999)
Enter a value between 1 and 999 to set the route preference for OSPF AS external
route type 2. The lower the value, the higher the chance the specified protocol will be
chosen as the best path for routing packets. The default value is 115.
Click Apply to implement changes made.
Static ARP Settings
The Address Resolution Protocol (ARP) is a TCP/IP protocol that converts IP addresses into physical addresses. This table
allows network managers to view, define, modify and delete ARP information for specific devices.
Static entries can be defined in the ARP Table. When static entries are defined, a permanent entry is entered and is used to
translate IP address to MAC addresses.
To open the Static ARP Settings window, open the Configuration folder, and then open the Layer 3 IP Networking
folder and click on the Static ARP Table link.

The following fields can be set:
Parameter Description
IP Address
The IP address of the ARP entry.
MAC Address
The MAC address of the ARP entry.
After entering the IP Address and MAC Address of the Static ARP entry, click Apply to implement the new entry. To
completely clear the Static ARP Settings, click the Clear All button.
RIP
The Routing Information Protocol is a distance-vector routing protocol. There are two types of network devices running
RIP - active and passive. Active devices advertise their routes to others through RIP messages, while passive devices listen
to these messages. Both active and passive routers update their routing tables based upon RIP messages that active routers
exchange. Only routers can run RIP in the active mode.
Every 30 seconds, a router running RIP broadcasts a routing update containing a set of pairs of network addresses and a
distance (represented by the number of hops or routers between the advertising router and the remote network). So, the
vector is the network address and the distance is measured by the number of routers between the local router and the
remote network.
