Display LE_ARP
Response Policy for
Route Descriptor
Displays the additional policy for handling LE_ARP requests for a specified
ELAN when the LAN destination is a route descriptor (Token Ring ELAN).
This policy is used in conjunction with the LE_ARP response policy (see
“Display LE_ARP Response Policy” on page 331) and is applicable only
when the “Respond” option is selected in that policy (see Table 50).
When the “Respond” policy is selected, the address table of the LES in
the CoreBuilder 7000 is searched for the LAN destination. If the LAN
destination is not found and is a Route Descriptor, this policy gives you
the option of rejecting the LE_ARP request. You can select between the
options:
■
Reject the LE_ARP request
■
Forward the LE_ARP request to all LECs in accordance with the LE_ARP
response policy
Note that all route descriptors are required by the LANE specification to
be registered at the LES (no proxy LECs are allowed for route descriptors).
This command essentially handles those cases for which the LAN
destination exists but was not registered at the LES – in contradiction to
the LANE specification.
This parameter is valid only in a Token Ring ELAN.
