(14) Use soft reconfiguration, where practical. BGP…It's only the biggest routing protocol in the world! I have seen lot of guys which say that next-hop-self feature in BGP is used for the E-BGP peering. In most practical implementation, though, the BGP next-hop is reachable through a more specific route usually a connected route for eBGP and IGP route for iBGP. When using OSPF over an MPLS VPN, things are pretty straightforward- you receive (and send) routes to your provider, who in turn transports your routes via BGP, and redistributes those into your OSPF process at other sites. To demonstrate that SNooPy is practical, we apply it to three example applications: the Quagga BGP daemon, a declarative implementation of Chord, and Hadoop MapReduce. It's only the biggest routing protocol in the world! Hope I have been informative; more practical examples on using BGP communities is coming in later posts. Practical LISP – Basic Control Plane.
