hello,
create 3 subnets, specify each default gateway.
configure your switchports belong to what vlan.
configure the router to be dhcp relay agent - specify the dhcp server.
done.
ps:
if you dont have vlan capable NIC/router - then you should forget it.
vlan is not an NIC with multiple IPAddr in it.
cheers...

Hi.
I want to use the DHCP server that comes with vxWorks 6.4.
The DHCP server implementation has a table that contains addresses of DHCP servers that will receive a copy of all the client requests that the local server gets, thus the server acts as a dhcp relay at the same time.
Can anyone... (4 Replies)

ng_vlan
NG_VLAN(4) BSD Kernel Interfaces Manual NG_VLAN(4)
NAME
ng_vlan -- IEEE 802.1Q VLAN tagging netgraph node type
SYNOPSIS
#include <sys/types.h>
#include <netgraph.h>
#include <netgraph/ng_vlan.h>
DESCRIPTION
The vlan node type multiplexes frames tagged according to the IEEE 802.1Q standard between different hooks.
Each node has two special hooks, downstream and nomatch, and an arbitrary number of ``vlan'' hooks, each associated with a particular VLAN
tag.
An ETHERTYPE_VLAN frame received on the downstream hook with a tag that the node has been configured to filter is sent out the corresponding
``vlan'' hook. If it does not match any of the configured tags, or is not of a type ETHERTYPE_VLAN, it is sent out the nomatch hook. If the
nomatch hook is not connected, the packet is dropped.
An Ethernet frame received on the nomatch hook is passed unmodified to the downstream hook.
An Ethernet frame received on any of the ``vlan'' hooks is tagged accordingly and sent out the downstream hook.
HOOKS
This node type supports the following hooks:
downstream Typically this hook would be connected to a ng_ether(4) node, using the lower hook.
nomatch Typically this hook would also be connected to an ng_ether(4) type node using the upper hook.
<any valid name>
Any other hook name will be accepted and should later be associated with a particular tag. Typically this hook would be attached
to an ng_eiface(4) type node using the ether hook.
CONTROL MESSAGES
This node type supports the generic control messages, plus the following:
NGM_VLAN_ADD_FILTER (addfilter)
Associates a hook with the tag.
NGM_VLAN_DEL_FILTER (delfilter)
Disassociates a hook from the tag.
NGM_VLAN_GET_TABLE (gettable)
Returns a table of all hook/tag associations.
EXAMPLES
#!/bin/sh
ETHER_IF=rl0
ngctl -f- <<EOF
shutdown ${ETHER_IF}:
mkpeer ${ETHER_IF}: vlan lower downstream
name ${ETHER_IF}:lower vlan
connect ${ETHER_IF}: vlan: upper nomatch
EOF
ngctl mkpeer vlan: eiface vlan123 ether
ngctl msg vlan: addfilter '{ vlan=123 hook="vlan123" }'
SHUTDOWN
This node shuts down upon receipt of a NGM_SHUTDOWN control message, or when all hooks have been disconnected.

HISTORY
The ng_vlan node type appeared in FreeBSD 4.10.
