Description
This command is used to configure DHCP relay Option 60 default relay servers. When there are no
match servers found for the packet based on Option 60, the relay servers will be determined by the
default relay server setting. When drop is specified, the packet with no matching rules found will be
dropped without further processing. If the setting is no- drop, then the packet will be processed further
based on Option 61. The final relay servers will be the union of Option 60 default relay servers and the
relay servers determined by Option 61.
