RE: DHCP Requests across VLANs [7:8689]

Yes you can. The DHCP requests will have to be routed via the MSFC or an external router. As the DHCP requests are broadasts the router will not forward these by default. You will have to set up a helper address on each interface that a broadcast is received on specifying the destination unicast o

Re: DHCP Requests across VLANs [7:8689]

If you served all your addresses from the same scope, you would have serious issues routing issues. Best practises dictate that you assign a scope per VLAN. Pete *** REPLY SEPARATOR *** On 6/15/2001 at 5:40 AM [EMAIL PROTECTED] wrote: >Hi all, > >In a Cat6509, we have created

Use the ip helper-address command and you need a different scope for each Vlan. - Original Message - From: "[EMAIL PROTECTED]" To: Sent: Friday, June 15, 2001 5:40 AM Subject: DHCP Requests across VLANs [7:8689] > Hi all, > > In a Cat6509, we have created three VLANs. In one of the th

Re: DHCP Requests across VLANs [7:8689]

There is an easy Win NT solution. You can have a one of the servers or workstations act as a DHCP relay for the other subnets. They will listen dor DHCP broadcats and forward them to the proper DHCP server. ""[EMAIL PROTECTED]"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Hi a

Re: DHCP Requests across VLANs [7:8689]

Start a session with the router and insert a 'ip helper' address. Be carefull though...by default, for whatever reason, cisco thinks netbios broadcast and name resolution along with dns and a few other broadcasts should be forwarded as well. You'll need to manually shut these off via 'no ip forw

Re: DHCP Requests across VLANs [7:8689]

And no... You need to define 3 scopes one for each vlan/network. The router then unicasts the original broadcast and replaces the network field which originates as 0 with the proper subnet the station is on. The dhcp server then sees a request from the workstation and answers appropriately f

Re: DHCP Requests across VLANs [7:8689]

Greetings, Question 1) Yes - using the "ip helper address " command on the router interfaces for the VLANs that don't have a DHCP server. Question 2) Technically, yes you can. But only by bridging on the router interfaces for the VLANs. However, it does fall under the first rule of networking, "
