LE_ARP Policy Configuration 289
Display LE_ARP
Response Policy for
Route Descriptor
Display 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. (For
more information, see “Display LE_ARP Response Policy” on page 286.)
The policy is applicable only when the “Respond” option is selected in
that policy. (See Table 38.)
When the Respond policy is selected, the address table of the LES in the
CoreBuilder 9000 ATM Enterprise Switch is searched for the LAN
destination. If the LAN destination is not found and is a Route Descriptor,
this policy gives the 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
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.
