Which two statements are correct about IS-IS interface metrics? (Choose two.)
Which two statements are correct about IS-IS interface metrics? (Choose two.)
By default, an IS-IS interface has a maximum metric value of 63. When wide metrics are configured, an IS-IS interface can have a maximum metric value of around 16 million. These configurations enable IS-IS to handle larger networks and more complex topologies by allowing for higher metric values.
it should be BD : metric—Metric value. Range: 1 through 63, or 1 through 16,777,215 (if you have configured wide metrics) Default: 10 (for all interfaces except lo0), 0 (for the lo0 interface)
Correct. Normally, IS-IS metrics can have values up to 63. The total cost to a destination is the sum of the metrics on all outgoing interfaces along a particular path from the source to the destination. By default, the total path metric is limited to 1023.
I think correct, B,D
All IS-IS routes have a cost, which is a routing metric that is used in the IS-IS link-state calculation. The cost is an arbitrary, dimensionless integer that can be from 1 through 63, or from 1 through 16,777,215 (224 – 1) if you are using wide metrics.
BD CORRECT
Maximum metric value 63 wide metrics enable an is-is interface to have a maximum metric value of around 16 million
BD are the correct ones. By default the metric values is up to 63 for an ISIS enabled interface (this is why 1023 is the default max metric for any ISIS path.....the metric can't go much higher is we calculate based on interfaces using non-wide values (up to 63), so adding multiple less-than-63 interfaces can't result easy in a summary more than 1023.
BD should be the answer
