Configuring Distributed DHCP Scopes
Instant allows you to configure the DHCP address assignment for the branches connected to the corporate
network through Virtual Private Network (VPN). You can configure the range of DHCP IP addresses used in the
branches and the number of client addresses allowed per branch. You can also specify the IP addresses that
must be excluded from those assigned to clients, so that they are assigned statically.
Instant supports the following distributed DHCP scopes:
l
Distributed, L2—
In this mode, the VC acts as the DHCP server, but the default gateway is in the data
center. Based on the number of clients specified for each branch, the range of IP addresses is divided.
Based on the IP address range and client count configuration, the DHCP server in the VC controls a scope
that is a subset of the complete IP address range for the subnet distributed across all the branches. This
DHCP assignment mode is used with the L2 forwarding mode.
l
Distributed, L3
—In this mode, the VC acts as the DHCP server and the default gateway. Based on the
number of clients specified for each branch, the range of IP addresses is divided. Based on the IP address
range and client count configuration, the DHCP server in the VC is configured with a unique subnet and a
corresponding scope.
