4.7 NSP and VSR-NRC PCE Redundancy

This feature introduces redundancy support to the PCE and PCC capabilities.

A CLI command parameter has been introduced in the PCC for configuring the PCEP

session to the standby backup PCE peer. A preference parameter value is used to

specify the primary and the standby backup PCE peer in the config>router>pcep>

pcc context:

peer ip-address preference preference

A maximum of two PCE peers are supported. The PCE peer that is not in overload

is always selected by the PCC as the active PCE. However, if neither of the PCEs

are signaling the overload state, the PCE with the higher numerical preference value

is selected. In case of a tie, the PCE with the lower IP address is selected.

In order to change the value of the preference parameter, the peer must be deleted

and recreated.

referred to as geo-redundancy.
