Hi,

First and foremost, perimeter devices should be configured with out-of-the box security. Confgure your switch/router with the following:

Block/deny traffic originating from external network using these addresses 10.0.0.0/8, 127.0.0.0, 172.16.0.0/and 192.168.0.0 towards your perimeter devices.

With regards to BGP, routes that should not be advertised nor accepted should be filtered. This is done by configuring filter-lists.

Thanks,
