IP Helper causing an Election
I have several subnet on a single domain separated by several routers. I use IP helper-address for the remote sites to get to the DHCP server. I noticed that in my event viewer on my PDC I am getting a RDR error 8003. An election is being held for the Master Browser. I checked tech-net and I found that the problem is which port 137 and port 138 Netbios Nameserver and Datagram server. My question is ... how do I disable these 2 ports ? If anyone has had similar experience I would interested in hearing about it and your solutions. Thanks in advanced rgds, Manolito **NOTE: New CCNA/CCDA List has been formed.

FW: IP Helper causing an Election
Nevermind.. I found it. no ip forward-protocol udp netbios-ns no ip forward-protocol udp netbios-dgm ip forward-protocol udp bootpc When I checked my event viewer on the PDC I am no longer seeing RDR error 8003 where elections for the master browser where constantly occurring. Now I have more bandwidth to do more productive things. :) rgds, Manolito -Original Message- From: Liwanag, Manolito Sent: Thursday, October 05, 2000 9:29 AM To: 'Cisco Group Study' Subject: IP Helper causing an Election I have several subnet on a single domain separated by several routers.

I checked tech-net and I found that the problem is which port 137 and port 138 Netbios Nameserver and Datagram server. My question is ... how do I disable these 2 ports ? The 'ip helper address' enables forwarding of several broadcast types, mostly UDP, such as BOOTP, DHCP, TFTP, DNS, and you guessed it, NetBIOS. Use the 'no ip forward-protocol udp 137', etc., to disable forwarding of any unwanted types. Many people quite mistakenly believe that 'ip helper-address' is just for BOOTP/DHCP. They are mistaken :-) Personally, I would prefer a new 'ip dhcp-forward a.b.c.d' type command to the older, overloaded helper-address.
