MA Project proposal

• Create logical route exchange system which
• Peers with at least 2 eBGP speaking routers
• Applies policy learned via RPSL
• Redistributes policy based routes
• Build system based on
• NetBSD
• GateD
• RSD

Step 1 LRX

• Logical Router eXchange
• Take BGP input from several peers
• Incorporates policy information
• RPSL
• Other
• Outputs BGP to peers
• IPv4 only
