IPv4 Routes

When the device is in Layer 3 system mode, this page enables configuring and
viewing IPv4 static routes on the device. When routing traffic, the next hop is
decided on according to the longest prefix match (LPM algorithm). A destination
IPv4 address may match multiple routes in the IPv4 Static Route Table. The device
uses the matched route with the highest subnet mask, that is, the longest prefix
match. If more than one default gateway is defined, the lowest IPv4 address from
among all the configured default gateways is used.
To define an IP static route:
Click IP Configuration > IPv4 Management and Interfaces > IPv4 Routes.
The IPv4 Routing Table is displayed. The following fields are displayed for each
entry:
• Destination IP Prefix—Destination IP address prefix.
• Prefix Length— IP route prefix for the destination IP.
• Route Type—Whether the route is a local, reject or remote route.
• Next Hop Router IP Address—The next hop IP address or IP alias on the
route.
• Route Owner—This can be one of the following options:
Default
- —Route was configured by default system configuration.
Static
- —Route was manually created.
DHCP
- —IRoute was received from a DHCP server.
• Metric—Cost of this hop (a lower value is preferred).
• Administrative Distance—The administrative distance to the next hop (a
lower value is preferred). This is not relevant for static routes.
• Outgoing Interface—Outgoing interface for this route.
Click Add.
Enter values for the following fields:
• Destination IP Prefix—Enter the destination IP address prefix.
• Mask—Select and enter information for one of the following:
- Network Mask—IP route prefix for the destination IP.
