Hi,

I had a doubt ->

2 routers A and B have an ospf adjacency.

Router A sends an ASExt lsa for network N1/m1 with LSID = N1.
Then Router A goes down & comes up again & reoriginates
ASExt lsa for network N1/m2 with LSID = N1 and then
gets adjacent with Router B.

**where m1 != m2 & they are multiple of 8. (/8, /16..)
also assuming that all other parameters are same.

However in this case the DB Exchange will fail to
synchronize these LSAs bcoz they appear
to be similar- LSID, SeqNum, Checksums being equal**
and thus will have to wait for the LSA to get refreshed.

I was wondering whether this can be resolved faster.

Thanks
Parag
