Mani,
This question has been discussed at some length here on GS. You may want to
check the archives.
To answer your question, however, that command does what you would expect it
to do - it provides dhcp clients with the ip address of 2 default gateways.
And, the first gateway is the primary gateway.
If the first gateway fails, the workstation can use the 2nd gateway.
But, suppose the workstation - I believe Win hosts behave this way - can't
make use of the 2nd gateway? IOW, if the first gateway becomes unavailable,
the Win host can't automatically and quickly use the 2nd gateway. What
happens then?
Wouldn't the Win host lose all current sessions? Is that OK? Will using a
2nd gateway meet the requirements of the task?
In the lab, I would suggest you implement a solution that will work
regardless of what type of hosts are being used on the segment.
HTH, Tim

Subject: dhcp- default-router 100.1.1.1 100.1.1.2
Guys,
What is the function of providing two default gateway ip advertisement in
dhcp.
R1--------VLAN30 100.1.1.x/24---------R2
100.1.1.1 100.1.1.2
================================
R1 config:
ip dhcp pool ABC
default-router 100.1.1.1 100.1.1.2
network 100.1.1.0 netmask 255.255.255.0
dns abc.com
lease 3
=================================
-Guys look at the defalut router command, is it says if DG as R1 and the
second DG is R2
-Is it a right configuration, can it be configured to replace HSRP concepts
-If not what is the purpose and operation of defining two default gateways.
thanks
Mani
