Table 6-4 Configuring static routes
Procedure Steps
Adding a static route 1.Select the Destination IP field of an inactive route
2.Edit the IP address
3.Select the Len field
4.Enter the subnet mask value of the destination network. Value 0 to32.
The subnet mask is determined by the number of 1’s left justified in a 32-bit
submask field, with the rest of the field set to zeros. The subnet mask
describes how many bits in the destination IP network address are valid, and
are to be matched against incoming packet’s destination address.
5.Select the Next Hop IP field 2 or select the Interface field 3 to enter either the IP
address for routers on numbered interfaces or to enter the egress port.
Enter the IP address for routers on numbered interfaces (Ethernet).
This is the IP address of the router where incoming matching destination IP
packets are sent. This IP address must be on the same subnet as one of the
numbered ports.
Or
Set the egress port to either NET1, NET2, ENET-0, Bundle0. This identifies
the physical WAN or LAN port associated to the route.
6.Set the
Metric
field 4
The metric specifies the route cost. Enter a number between 1 and 255 to
define the hop count. Use this count to create preferential hops for prioritizing
routing entries.
If more than one route of equal cost is found for a particular destination, the
routing engine will distribute the packets equally among the available routes
using a round-robin algorithm. See “Setting the Metric parameter for Load
Balancing” below.
If multiple routes are found with unequal costs then the route with lesser cost
metric is chosen.
7.Set the
Action
field 5 to Add
If this new route is accepted by the routing engine the status field 6will change
from Inactive to Active.
If the route is not accepted, the action field 5 will change to Modify. You will
have to change one of the settings in the route and try to add it again.
