MPLS + SDN + NFV World  - Paris 2016

MPLS + SDN + NFV World - Paris 2016

Juniper is proud to be a Diamond Sponsor of MPLS+SDN+NFV World in Paris (8 - 11 March 2016). We have some great live demonstrations on our booth so, if you plan to be there, a couple of minutes reading this may help you plan your time wisely. 

 

We look forward to seeing you there.

LFA analysis with WANDL - Part II (topology refinement)

LFA analysis with WANDL - Part II (topology refinement)

Following up my previous LFA analysis with WANDL - Part I

post, I am reviewing now different Loop-Free Alternate (LFA) academic definitions and references for most applicable topologies and continue the analysis with the WANDL IP/MPLSView toolset.

 

This WANDL IP/MPLSView platform allows simulation of topology changes and recomputing the LFA analysis.

 

These simulation results turn out to be aligned with theoretical expectations derived from mathematical calculations and standard models.

LFA analysis with WANDL - Part I

Loop Free Alternates (LFA) or IP Fast Reroute (FRR) crystallized some years ago with a basic specification in [RFC5286] as a noteworthy concept to provide standalone backup path calculations just based on route inequalities.

Tweaking BGP add-paths

Tweaking BGP add-paths

 

This post follows-up my previous article Granular BGP advertise-external for MPLS L3VPNs with the intention to tweak and illustrate the BGP add-path feature implementation in Junos OS for IPv4 unicast and IPv6 labeled-unicast (6PE) routes. BGP add-paths provide a more comprehensive path diversity approach than diverse paths or advertise-external and in my view, multiple applications can be based on Junos OS BGP add-path tactical deployment in default instance tables.

Granular BGP advertise-external for MPLS L3VPNs

Granular BGP advertise-external for MPLS L3VPNs

In some BGP multi-homed environments between networks, it is possible to achieve shorter convergence times by using certain features beyond traditional [RFC4271] BGP rules. One of these features is the so-called BGP advertise-external or best-external, so that Autonomous System Border Routers (ASBRs) also advertise the best externally received path, even though it may not result as the ultimate best path from the selection algorithm.

Inter-AS Option A+B for IPv4 and IPv6 L3VPNs - Part III (Aggregation and filtering)

Inter-AS Option A+B for IPv4 and IPv6 L3VPNs - Part III (Aggregation and filtering)

This post finishes the Inter-AS Option A+B article series in this blog after Inter-AS Option A+B for IPv4 and IPv6 L3VPNs - Part I and Inter-AS Option A+B for IPv4 and IPv6 L3VPNs - Part II (Label substitution), bringing in a more comprehensive application for this use case: the ability to perform IPv4 and IPv6 route aggregation and filtering at this hybrid interconnect.
