default-frr-protection
Use this command to configure the default method of fast reroute protection when sender has not specified a method via FRR object but asked for local protection. This command is particularly useful with interop with Cisco as Cisco doesn’t send FRR object in path message. By default, default FRR protection considered to be one-to-one in OcNOS and in case of interop with Cisco where default protection needed is facility, this command shall be configured on all OcNOS devices in the network.
Note: Having this command configured in one OcNOS device and not configured in other OcNOS device in the network will cause unpredictable behavior as RFC recommendation for merge node behavior of facility and one-to-one are different.
Note: This command is applicable only when path message contains local protection flag set but doesn’t contain FRR object. When FRR object mentions protection type explicitly, this command is not applicable and also, if path message doesn’t request local protection, then also this command is not applicable.
