Hello Guys,
I have Two routers are configured with HSRP and have DHCP POOL configured on
Both Rotuer1 and Router2 .
All the user clients are getting ip from DHCP within the Same WAN..
Rotuer1:
ip dhcp excluded-address 10.120.101.141 10.120.101.254

If you look at Router 2 IP DHCP bindings it is releasing ip address even of
the excluse list of R2 DHCP Scope.
R1 - EXCLUDE SCOPE :- 10.120.101.141 - 10.120.101.254
R2 EXCLUDE SCOPE :- 10.120.101.1-140 .....but still R2 is giving ip's from
excluse list.
Also I am not sure why these DHCP Conflicts and PING Conflict are keeping
popping up, due to these my SCOPE is getting fulled and my few client failed
get new IP address.
IS this some thing to do with this command no ip dhcp conflict logging
needed to resolve this issue?
*Appreciate all your efforts!*
Regards,
Akber Mirza.
