Assume the following prefixes available in your routing table (taken
from original example):
10.1.1.0/28 OSPF
10.1.0.0/24 EIGRP
10.1.1.0/26 Static
All three would be entered into the table since they have different
mask lengths. If a packet destined for 10.1.1.1 were to hit the router,
which route would it choose? The /28 would be used because it is the
matching prefix with the longest mask length.
To the person who contends that the /26 would be chosen, can you
explain your reasoning?

John

The most specific route- mask wise. Easy peasy lemon squeezy. Ask me
