Note
|
PfR target discovery must be configured before bandwidth resolution is enabled. Both dynamic and static target discovery is
supported by PfR bandwidth resolution.
|
The following configuration can be used in multihop networks where the network cloud between the head office and branch offices
or remote sites is not controlled by the customer or is not SAF-enabled. Configuration examples are shown for three master
controllers, one at the head office and two at branch offices. PfR bandwidth resolution is enabled on all PfR master controller
(MC) devices. Output for the
show pfr master bandwidth-resolution command is shown for all three sites.
Note
|
In the following examples, the hub and spoke device hostnames were configured as “Router-hub,” “Router-spoke1,” or “Router-spoke2,”
but the device can be any device with routing capability that supports PfR.
|
Hub MC Bandwidth Resolution Configuration
The hub device has routing capability and is in the head office. In this example, PfR bandwidth resolution is enabled on the
master controller.
Router-hub> enable
Router-hub# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router-hub(config)# pfr master
Router-hub(config-pfr-mc)# bandwidth-resolution
Router-hub(config-pfr-mc)# end
Spoke1 MC Bandwidth Resolution Configuration
The spoke1 device has routing capability and is in a branch (spoke) office. In this example, PfR bandwidth resolution is enabled
on the master controller at the branch office.
Router-spoke1> enable
Router-spoke1# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router-spoke1(config)# pfr master
Router-spoke1(config-pfr-mc)# bandwidth-resolution
Router-spoke1(config-pfr-mc)# end
Spoke2 MC Bandwidth Resolution Configuration
The spoke2 device has routing capability and is in a second branch (spoke) office. In this example, PfR bandwidth resolution
is enabled on the master controller at the second branch office.
Router-spoke2> enable
Router-spoke2# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router-spoke2(config)# pfr master
Router-spoke2(config-pfr-mc)# bandwidth-resolution
Router-spoke2(config-pfr-mc)# end
Example Output for PfR Bandwidth Resolution
The following output is from the master controller for the hub device after PfR bandwidth resolution is enabled:
Router-hub# show pfr master bandwidth-resolution all
