Creating a DVMRP accept policy

Before you can apply an accept policy to an interface, VLAN, or port, you must first create the policy.

You can create one or more IP prefix lists and apply that list to any IP route policy. A prefix list with a 32 bit mask is equivalent to an address. A prefix list with a mask less than 32 bits can be used as a network. If you configure the MaskLenFrom field to be less than MaskLenUpto field, it can also be used as a range.

To create a DVMRP accept policy:

  1. From the Device Manager menu bar, choose IP Routing > Policy.
    2. The Policy dialog box opens with the Prefix List tab displayed.
  2. Click Insert.
    3. The Policy, Insert Prefix List dialog box displays.
  3. Create a prefix list for the new policy by entering the following information in the Policy, Insert Prefix List dialog box. (Refer to Table 227 for a description of the information for the required fields in this dialog box):
    1. An ID for the prefix list (unique number) in the Id field.
    2. An IP address in the Prefix field.
    3. The length of the prefix mask (range is 0 to 32) in the PrefixMaskLen field.
    4. A name for the prefix list in the Name field.
    5. MaskLenFrom and MaskLenUpto are not required to create an accept policy. For information on these parameters, refer to Table 227
    6. Click Insert.
  4. Repeat step 3 to add additional IP addresses to the prefix list you created.
    5. You can also create additional prefix lists by repeating step 3.
  5. From the Policy dialog box, click the Route Policy tab.
    6. The Route Policy tab opens.
  6. Click Insert.
    7. The Policy, Insert Route Policy dialog box displays.
  7. Create the new policy by entering the following information in the Policy, Insert Route Policy dialog box:

    Note Note: Not all the fields in the Policy, Insert Route Policy dialog box apply to the process of creating a DVMRP policy.


    1. A number for the policy in the Id field.
    2. A number for the policy (range is 1 to 65,535) in the SequenceNumber field.
    3. A name for the policy in the Name field.
    4. Select DVMRP from the MatchProtocol field.
    5. Enter the applicable name(s) of the prefix lists you created in steps 3 and 4 in the MatchNetwork, MatchIPRouteSource, and MatchNextHop fields.
      6. You can enter a single or several prefix lists. You can select up to four lists. To enter the names of the prefix list(s), click the ellipse button to the right of the field, select the appropriate name(s) from the dialog box, and click OK. To select multiple names, use the CTRL key. To deselect an entry, use the ALT key.
    6. Enter a value (range is 0 to 65,535) in the MatchMetric field.
    7. Enter a value (range is 0 to 65,535) in the SetMetric field.
    8. Click Insert.
