EIGRP Loop-Free Alternate (LFA) Fast Reroute (FRR) is a feature that allows EIGRP to switch to a backup path in less than 50 ms. Fast reroute means we switch to another next hop, Loop-free alternate is an alternative path in the network that is loop free. Now you might be thinking that this sounds familiar. After all, EIGRP has feasible successors. CLI Statement. QFX Series,EX4600,MX Series,SRX Series,M Series,T Series,PTX Series,ACX Series.

There are two approaches for the fast reaction: Fast convergence and Fast reroute. When a local failure occur four steps are necessary for the convergence. 1. Failure detection. 2. Failure propagation.

The PLR swaps the incoming label and pushes a TE FRR label onto the label stack. The backup TE LSP terminates on the device known as the merge point ( MP), We also show how much extra backbone resource is needed to support Fast Reroute and how can that be reduced by taking advantage of Constrained Shortest Download scientific diagram | Fast reroute protection by using the detour/bypass LSP. from publication: Recent trends in MPLS Networks: Technologies, Segment Routing Fast Reroute – Traffic Engineering with Segment Routing uses LFA mechanism to provide 50 msec fast reroute capability.

Fast Reroute, as the name implies, is used to create an MPLS network, that has similar convergence properties of SONET/SDH APS of about 50 ms. MPLS Traffic Engineering Fast Reroute Link Protection – I will explain it in plain English and the most important point of MPLS TE FRR Link Protection among other Fast Reroute mechanisms.

In Secondary Paths (End-to-End Protection), the configuration overhead was too much. Fast Reroute (FRR) reduce this configuration overhead with automatic path calculation.

Fast Reroute was also tested on the Cisco site which was subsequently disconnected by means of a serial link between routers P2 and P3. Every single second was sent an ICMP message from PC2 to PC1. Because only two ICMP messages were lost, the convergence time of Fast Reroute was just 2 seconds, which can be seen in Figure 11. After the failure of a network node or a link, a period of impaired connectivity is experienced until the network reconverges. During this period, specific destinations are not reachable, causing issues specifically with critical and time-sensitive services such as Voice over IP. The process of network reconvergence can last from a few milliseconds to tens of seconds.
