Query about LATCH Vs RELATCH

Hi,



I have a query about the difference between Latch and Relatch. I am testing
BGF, and in my scenario when Latch is followed by Relatch then it is working
fine i.e. first it learn the packets from the source IP (except remote
descriptor IP) and when did RELATCH then learned the packets from new source
IP and drops the packets from the previous IP.

Now when I am doing a scenario Latch followed by Latch then also first it
learns the packets from the source IP and when did LATCH then it learn the
packet from new source IP and drops the packets from previous IP.



Here I am not able to figure out what is the difference between Latch and
Relatch because in the above scenario I can see LATCH is doing the same
thing which RELATCH does. Why RELATCH comes into the picture?



Please help me to figure out this, so that can proceed. Your help would be
appreciable.
