Default global metric for ISIS

IPv6 metric behavior with multi-topology configuration
The default-link-metric for IPv6 will depend upon the multi-topology configuration.
No multi-topology: The IPv6 default-link-metric will be same as that configured for IPv4
address-family.
Multi-topology: The IPv6 default-link-metric will be equal to the value configured for IPv6
address-family.
Multi-topology transition: The IPv6 default-link-metric will be equal to the value configured for IPv6
address-family.
Metric behavior with change in metric-style
There are two types of metric styles in ISIS, narrow metric and wide metric. The range of the metric
value is different in both of these styles. If there is a change in the metric-style configuration, the
default-link-metric will also change with it. The new value of the default-link-metric will be equal to
the minimum of a) configured value and b) the maximum value supported for the new metric-style.
If the metric style changes from narrow metric to wide metric, there will be no change in the value
of default-link-metric.
If the metric style changes from wide metric to narrow metric, and if the value of default-link-metric
is greater than 63, the default-link-metric will now take the value 63, as it is the maximum
supported in the narrow metric.
ISIS Show command
The show isis command and show ipv6 isis command output has been modified to reflect
the default-link-metric configured.
