LMS with DNS switched off

Hi All,

I had to turn off DNS, on my customers server as half the devices were resolving to the ISDN interface. (round-robin DNS was switched off and the lowest ip address used to be given).

However after fixing all the addresses, the 'route print' cmd in windows displays all these /32 entries for the ISDN interfaces and other ip addresses also. Its definitely CW thats entering them, but why? It's never done this before. This an added feature of 2.6?

Re: LMS with DNS switched off

This could be DFM pinging each of the interfaces for reachability. However, this is not new to 2.6, and unfortunately cannot be easily disabled (see CSCee39389 and CSCsb48643). However, there is a workaround, and a script can be given if you contact the TAC.

This may also be Device Discovery picking up these interfaces, and using the IPs for management purposes. When you say you fixed all the addresses, does that mean you checked to make sure those addresses are no longer present in DCR? If DCR has those IP addresses, then that's what applications will use to manage the devices.
