Figure 24 Two Interfaces Connected To The Same Subnet
Figure 25: Two CLIMs Connected to the Same Subnet shows subnet routes on two CLIMs:
There are two interfaces on two CLIMs of the provider on the same IP subnet (A.0)
CLIMs are selected in round robin order for outgoing connections
The route through CLIM B continues to be used even after it has lost link pulse
The network becomes unreachable for half of the outgoing connections.
