[OPLINTECH] Cisco Router Question

[Ron Stroup]

Mindy,

If you just want to update the DNS servers in your configuration you do
not need a TFTP server.  

If your old dns servers are:
10.10.10.1
10.10.10.2

And your new dns servers are:
10.10.20.1
10.10.20.2

Issue the following commands:

Conf t
No ip name-server 10.10.10.1
No ip name-server 10.10.10.2
Ip name-server 10.10.20.1
Ip name-server 10.10.20.2
End
Write mem

Subject: [OPLINTECH] Cisco Router Question

Put in new DNS servers and need to update the startup config file for
the Cisco Router that subnets our network to include the new DNS IP
addresses.  My thought is to copy the startup config file, edit it and
TFTP it back onto the router.  Problem is, I have never done this
before.  So, I am looking for any caveats, tips, suggestions, etc. from
those experienced at this.  I also am open to suggestions for a good,
easy-to-use, free TFTP product to use.

Thanks,
