ONS 15454 IP Addressing Scenarios
•Mask—Enter a subnet mask. If the destination is a host route (i.e., one CTC computer), enter a 32-bit
subnet mask (255.255.255.255). If the destination is a subnet, ad just t he su bne t m ask a cco rding ly,
for example, 255.255.255.0. If the destination is 0.0.0. 0, en t er a su bnet mask of 0 .0.0. 0 to p rov ide
access to all CTC computers.
•Next Hop—Enter the IP address of the router port (in this example , 192 .1 68. 90.1) or the n ode IP
address if the CTC computer is connected to the node di rec tl y.
•Cost—Enter the number of hops between the ONS 15454 and the computer. In this example, the cost
is two, one hop from the ONS 15454 to the router and a seco nd hop fr om t he r out er to t h e CTC
workstation.
Step 4 Click OK. Verify that the static route displays in the Static Route window, or ping the node.
4.2.6 Scenario 6: Static Route for Multiple CTCs
Scenario 6 shows a static route used when multiple CTC computers need to access ONS 15 454s re siding
on the same subnet (Figure 4-7). In this scenario, CTC #1 and #2 and all ONS 15454s a re on the s am e
IP subnet; ONS 15454 #1 and CTC #1 are attached to LAN A. ONS 15454 #2 and CTC #2 are a ttached
to LAN B. Static routes are added to ONS 15454 #1 pointing to CTC #1, and to ONS 15454 #2 pointing
to CTC #2. The static route is entered from the node’s perspective.
