Some routes are not active and up even though they should be, such as:
s 10.102.0.0/16 10.1.1.1 1 -G---S-um---- Default 0d:0h:14m:3s
Whereas an active route that is working as intended would look like:
#d 10.110.0.0/16 10.110.1.3 1 U------um--f- Servers 0d:2h:12m:2s
Main thing to look for is the U flag on the route which means it is "up", and the # which means it is a preferred route.
