Hi, Does anyone have experience of the following please? C3550 allows the creation of a vrf and all seems to work ok from a routing perspective however clients within the vrf cannot obtain an IP address from dhcp on the switch. The dhcp pool is created. There is no option to specify vrf within the pool "ip dhcp use vrf connected" does not exist either. Other scopes exist which are not in the new vrf and they work ok. Sniffer traces show that the switch responded with an offer from the correct scope but from it's native ip address, not the vlan i/f within the relevent vrf. when the client responds to the offer there is no subsequent confirmation from the switch which seems to have lost track of the fact the client is in a different vrf? Given the age of the ios i expect an upgrade is required but does anyone know of one that works? Switch model is C3550-48-SMI Image is c3550-i9q312-mz.121-13.EA1a Many thanks in advance.

HiPaul, Thanks for this detailed response. I've just today managed to get a copy of a working config which does seem to be using dlsw - it includes the statements dlsw allroute-sna and allroute-netbios but other than that it's basic. It seems to work is spite of the fact there's nothing anywhwere that says it should? It's fairly small scale so I guess I'll try it and change to bridging if necessary. Cheers.
