[Chandra] The text "carried in the Path to" is intended because the expected outcome is not to apply long refresh in the two hop neighborhood. That is, if the Phop node (say node X) does not support the extensions, then two nodes downstream of node X must use backward compatible refresh interval. This will enable the NP-MP of node X to time out the path state normally when the refresh timeout expires.

Thanks,
Chandra.
