LSA origination prevented by existing LSA with same LSID but a different mask

Hi

How to find out the duplicate entry with different subnet mask:

%OSPF-4-CONFLICTING_LSAID: LSA origination prevented by existing LSA with same LSID but a different mask, Existing Type 171115136 LSA: LSID 255.255.255.240 0xA330280 New Destination: 255.255.255.255 0x29200

Hi Samarjit,

There is a cosmetic defect which is shifting variables in that error message:

CSCsm92436

Thus you see decimal value for ip address in Type, mask in LSID field, etc (all shifted left).

So for your message:

171115136 DEC = 0xA330280 HEX = 10.51.2.128  (if I decoded to benary correct  - pls double check ).

You can rate if was helpful.
