What is the meaning of the following IP ---0.0.0.0/1 , please explain @ Vishwajeet Rathore Sir..?

Hello Yogesh,

This route simply means we are matching any ip with mask value of 128.0.0.0.

It is more specific than normal default route.

SO if you have two paths for one you can configure 0.0.0.0/0 and the one you want to prefer you can use 0.0.0.0/1/
