Maximum reference bandwidth increased to 4 TB for IGP protocols

We've increased the maximum reference bandwidth for IS-IS and OSPF IGP protocols from 1 Tbps to 4 Tbps. The default bandwidth is 100 Mbps. You can increase the reference bandwidth to adjust the path metrics, which you use to determine the preferred path in case of multiple equal-cost routes to a destination. To configure the reference bandwidth, use the reference-bandwidth reference-bandwidth statement at the [edit protocols isis] hierarchy level or the [edit protocols (ospf | ospf3)] hierarchy level.
