Scenario 3: Replication between sites with dedicated interfaces
6.3.1.5
Daniel has two sites, each with a DR appliance that he wishes to configure as a replication pair over dedicated links.
Each DR appliance will have the following configuration:
• DR1 has 2x 10GB interfaces in bond0 with 2 x1GB interfaces not bonded dedicated to replication
• DR2 has 2x 10GB interfaces in bond0 with 2 x10GB interfaces not bonded dedicated to replication
Figure 5
In the default configuration of the DR, the default route for the system is always is set on the network which belongs to
bond0. In this example for both the DRs the default route points to the gateway on the 10.250.232.x network. This allows
for administration of the DR from anywhere on the network.
Example route:
[root@DR1 ~]# route
Kernel IP routing table
Destination Gateway
10.250.232.0 *
default
In order for the two DRs to replicate over the dedicated links, static routes should be provisioned in such a way that the
replication flows over those paths. This is done in the steps below.
