Also don't forget that the router routing table (the FIB) is built by picking the best routes from all tables received from all protocols, stored in different RIB. You can have the routes duplicated or a simple pointer to the existing route. | |

The line 1687609 BGP routes, using 103 MiB of memory sounds more sensible for the actual data alone. That would require about 64 bytes per route.
