Hey Silvio,

You atleast need 512 MB of DRAM to be able to handle full BGP internet routing table. Below is the documentation for it.

"To store a complete global BGP routing table from one BGP peer, it is       best to have a minimum of 512 MB or 1 GB of RAM in the router. If 256 MB of RAM       is used, it is recommended that you use more route filters. If you use 512 MB       of RAM, more Internet routes can be placed in the routing table with fewer       route filters."

Hence you take a best call. Kindly rate the helpfulness of this post.
