…e sending interval.

The hold time filled in the hello packets of a P2P link is calculated based on the level 1 configuration, while the hello timer is based on the level 2 configuration. If the hello interval times in level 1 and level 2 configurations are inconsistent, it may lead to neighbor establishment failure.
