and PE2. The bandwidth of one tunnel is 5 Mbit/s and the bandwidth of the other tunnel is 10
Mbit/s. The CEs in VPNA require 10-Mibt/s constant bandwidth for communication; therefore,
the tunnel with 10-Mbit/s bandwidth is used by VPNA exclusively to ensure the bandwidth. To
use the tunnels more efficiently, VPNB prefers the TE tunnels.
