Gracefully Upgrading JUNOS Devices with Dual RE’s

One of the coolest things about the routing plane with Juniper routers is the fact that you can have dual/redundant independent routing-engines. Routers are constantly making decisions, running algorithms, and updating the database for the correct way for traffic to get to every destination possible.  They do this to always have the quickest/most efficient route … Continue Reading

Both JUNOS and IOS-XR … Continue Reading

Yet another Definition of MPLS

MPLS is a highly scalable, protocol agnostic, data-carrying mechanism. In an MPLS network, data packets are assigned labels. Packet-forwarding decisions are made solely on the contents of this label, without the need to examine the packet itself. This allows one to create end-to-end circuits across any type of transport medium, using any protocol. The primary … Continue Reading
