The simplicity, elegance, and robustness of Juniper's solution make it much easier to troubleshoot and configure, when compared to
Cisco Routers, especially considering Cisco's implementation of BGP (why are IPv4 and IPv6 linked in Cisco configuration?).
Furthermore, the implementation of commit and rollback cannot be understated when compared to the Cisco solutions. This feature is a huge time saver when attempting to troubleshoot and remote configuration instances.
