Providing scalable NH-diverse iBGP route re-distribution to achieve sub-second switch-over time
The role of BGP inside an AS is to disseminate the routes learned from external peers to all routers of the AS. A straightforward, but …

Providing scalable NH-diverse iBGP route re-distribution to achieve sub-second switch-over time
Preventing the Unnecessary Propagation of BGP Withdraws
Due to the way BGP paths are distributed over iBGP sessions inside an Autonomous System (AS), a BGP withdraw that follows a failure may …
