Hello Mate!
For the purpose of peering with external BGP As and handle full BGP views - it is recommended to use NE40E-X8 sesries, which is designed to be used as ASBR.
Requirements for ASBR.
- Need to use are least V8R10 version to fully support Internet-exchange point peering
- Reach policy features - XPL
- Nigh Memory -
- Anti-DDOS protection
- O&M functionality
- IPv6 support
As the light Model you can try NE40E-X3A - but usually it is used for Route-reflectors or kind of low-level PE in ISP networks.
Take care and have a great day!
