Level 6

Hi Everyone,

 

If in FIB table BGP has 2 routes for the same destination and they both go via Different Interfaces of the

Router.

 

Does then BGP pick the route with smaller ranges?

does smaller range mean here small subnet mask?

 

Regards

Mahesh

Traffic always use the most specific route. If the two routes are equal, traffic is load balanced between the two.
