Re: Staic Routes on 1605 Router [7:52340]
Another silly suggestion... Are the Ethernet interfaces up? They must be no shutted as part of your config. Your config as you list it looks right to me. -S.

Can anyone please advise of the command(s) for a static route, if indeed this is the problem. Any suggestions would be appreciated.

Re: redundant MSFC synchronization problem [7:12360]
I went around about this with Cisco for some time. I made them change their docs. See the line: Caution Dual MSFCs in a single chassis are designed to be used in redundant mode only and you must configure both MSFCs identically; they must have the exact same configuration. Table 22-2 summarizes the identical requirements and the exceptions for Layer 3 redundancy for a single chassis. We do not support configurations where the MSFCs are not configured identically. at http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/sft_6_1/configgd/redund.htm -S. cisco_fun wrote: Thanks for the info. However as of now I am not looking for the high availability option. The current problem is that the second subnet (192.168.2.0) cannot access any other subnet other than the directly connected subnets. (since this subnet uses the MSFC2 as the primary module). The only way to make this work is disable the MSFC2 module ( i.e. disable module 16). can anyone suggest how to resolve this, since before the switch was rebooted this was working.

Re: [Re: Windows NT DHCP with multiple Scopes]
Two factors converge to make this work. 1.) The IP Helper address Converts the broadcast request to a unicast. The destination being the helper address, and the source address being the Router interface that received the request *Very Important* 2.) The NT server is configured with one interface/IP address. A scope is created for the directly connected network, and a scope is created for the network on the other side of the router. These two scopes are bound together as one superscope. (see NT/DHCP docs for how, like all things NT, it's just a few button-pushes). It works in this way. The DHCP server will assign addresses from a scope which corresponds to the directly connected network on which the receiving interface sits. The superscope binds the secondary network's scope to the directly connected networks scope, in effect, saying "it's ok to assign addresses from this scope to requests on this other directly connected network". Now, to answer your question. The source address of the forwarded request is on the other net (remember the changed source address above?). In this way, the NT server knows that it should assign an address from the other nets pool. HTH -S. Larry Lamb wrote: You'll only want the 1 IP on the server if the local network has 1 IP range. If memory serves me right, you just add a 2nd scope and setup the ip helper-address to the server. It acts as the DHCP relay and the server will know the request came from the other network. Hopefully someone will add something additional if this isn't correct. It's been ages since I've dealt with this.

Re: DHCP- Advise / Suggestions Apprciated
The problem you are having is due do DHCP functionality, not cisco/helper address related. The DHCP server which does not have a scope created on it is issuing a NACK for the IP request to the client. This is probably happening first because the NACKing server can tell that it is not configured with a scope for the requesting net faster than the assigning server can do a lookup and find a valid IP to assign. The client gets the NACK first and gives up. You can solve this one of two ways: Remove the helper address pointing to the second server. If its not configured to serve that subnet, then you are not gaining anything by having the helper address there, and actually causing you a problem. Alternately, if you want redundancy, split the scope between the two servers (as someone else has already suggested). Each DHCP server must have scopes defined on it for the nets it is receiving requests from or else it will generate the NACK. I have this problem all the time when an enterprising user installs NT Server with "all the options" (including DHCP Server) on their workstation. The enterprising user doesn't know anything about DHCP, leaves the scope empty (default), and DHCP on his broadcast domain grinds to a hault as his box starts NACKing valid requests. -S.

I have 2 DHCP servers and I have defined both the IP helper addressess in our routers Now, if a client quieries for an IP, which of the servers will respond first? The problem I have is we have defined one subnet in DHCP Server and not in the other. When this user is querying for an IP , he is not getting a response. interface Ethernet0 ip address 10.X.X.X 255.255.0.0 ip helper-address 10.X.1.X ip helper-address 10.X.1.Y The said subnet is defined in the DHCP server 10.102.1.Y but, still there is no response. when the client requests. The main reason we have 2 DHCP servers is for redundancy. Please note that they are independant of each other . Does this mean that , when the client is requesting, the router first forwards to the first DHCP server and since it is not getting a response , is dropping it?
