Scenario 4—GRE: Single Datacenter Deployment with No
Redundancy
This scenario includes the following configuration elements:
l Single VPN primary configuration using GRE
n Aruba GRE, does not require any configuration on the Dell Networking W-Series Mobility Controller that
acts as a GRE endpoint.
n Manual GRE, which requires GRE tunnels to be explicitly configured on the GRE-endpoint that can be a
Dell Networking W-Series Mobility Controller or any device that supports GRE termination.
l Tunneling of all traffic to datacenter
l Centralized L2 mode DHCP profile
l RADIUS server within corporate network and authentication survivability for branch survivability.
l Wired and wireless users in L2 mode
l Access rules defined for wired and wireless networks to permit all traffic
Topology
Figure 124 shows the topology and the IP addressing scheme used in this scenario:
Figure 124 Scenario 4 - GRE: Single Datacenter Deployment with No Redundancy
The following IP addresses are used in the examples for this scenario:
l 10.0.0.0/8 is the corporate network.
l 10.20.0.0/16 subnet is reserved for L2 mode.
