wide transition narrow default value (10) if the original value is
greater than 63. A message is sent to the
console.
wide transition narrow transition default value (10) if the original value is
greater than 63. A message is sent to the
console.
wide transition transition truncated value (the truncated value
appears in the LSP only). The original isis
metric value is displayed in the show
config
and show running-config
commands and is used if you change back
to transition metric style.
Moving to transition and then to another metric style produces dierent results.

Leaks from One Level to Another
In the following scenarios, each IS-IS level is congured with a dierent metric style.
