server
Syntax server server1 [server2...(up to 8 max)]
Context config>service>vprn>if>dhcp
config>service>vprn>sub-if>grp-if>dhcp
Description This command specifies a list of servers where requests will be forwarded. The list of servers can
entered as either IP addresses or fully qualified domain names. There must be at least one server
specified for DHCP relay to work. If there are multiple servers then the request is forwarded to all of
the servers in the list. There can be a maximum of 8 DHCP servers configured.
The flood command is applicable only in the VPLS case. There is a scenario with VPLS where the
VPLS node only wants to add Option 82 information to the DHCP request to provider per-subscriber
information, but it does not do full DHCP relay. In this case, the server is set to "flood". This means
the DHCP request is still a broadcast and is sent through the VPLS domain. A node running at L3
further upstream then can perform the full L3 DHCP relay function.
Default no server
Parameters server — Specifies the DHCP server IP address.
