DESCRIPTION
Use the top section to create routing table entries manually.
Select the domain to whose routing table you want to add this entry.
Enter the IP address and the number of bits in the subnet mask that define the
range of IP addresses to which this entry applies. If the destination IP address
of a packet is in this range, the MSC forwards the frame to the specified edge
router.
Enter the IP address to which the MSC forwards frames if the destination IP
address of a packet is in the specified range.
If this IP address corresponds to an edge router in the edge router screen (see
Section 11.17 on page 266), the MSC uses the associated VLAN ID. In addition,
• If the edge router is in the same domain as the entry, the entry is used for
upstream traffic.
• If the edge router is in a different domain than the entry, the entry is used for
downstream traffic.
If the specified edge router is not set up in the edge router screen, the MSC
uses the entry for downstream traffic and does not change the VLAN ID.
The metric represents the "cost" of transmission for routing purposes. IP routing
uses hop count as the measurement of cost, with a minimum of 1 for directly-
connected networks. Select the number that approximates the cost for this link
The number need not be precise, but it must be between 1 and 15. In practice, 2
or 3 is usually a good number.
If two entries have the same metric, the MSC uses the one with the lower IP
address.
If you want to set the IEEE 802.1p priority value of incoming frames, select the
check box and use the drop-down list box to select the priority value (0 to 7) to
use.
Click Apply to create the routing table entry. It is then displayed in the summary
table at the bottom of the screen.
Clicking Apply saves your changes to the MSC's volatile memory. The MSC
loses these changes if it is turned off or loses power, so use the Config Save
link on the navigation panel to save your changes to the non-volatile memory
when you are done configuring.
Click New to set the screen to configure a new entry.
Click Cancel to start configuring this section of the screen again.
The bottom section displays routing table entries created manually. It does not
show entries added automatically by the MSC. See
look at the full routing table(s) for selected domain(s).
Select a domain for which you wish to view information and click Load to
display it.
This field displays the number of the entry.
These fields display the IP address and the number of bits in the subnet mask
that define the range of IP addresses to which this entry applies. If the
destination IP address of a packet is in this range, the MSC forwards the frame
to the specified edge router.
This field displays the IP address to which the MSC forwards frames if the
destination IP address of a packet is in the specified range.
This field displays the "cost" of transmission for routing purposes.
