Question

Accepted Answer

EIGRP variance is used to load balance traffic across unequal cost paths. Route influence EIGRP is used to manipulate the metric of a route. Route Reflector is used in BGP to reduce the number of iBGP peerings.

EIGRP variance is used to balance traffic across multiple paths with different costs
Route influence EIGRP is used to manipulate the metric of a route to influence the path selection
Route Reflector is used in BGP to reduce the number of iBGP peerings by reflecting routes to other iBGP peers
