Strategies to enhance the scale and performance of routing, aiming for faster convergence, improved stability, and optimized hardware utilization. Disclaimer: The RIB and FIB scales discussed in this article are based on lab exercises and may not necessarily represent the...
Optimizing Failover Convergence for Enhanced Network Resilience with BGP PIC implementation in JUNOS. Introduction This blog will delve into multiple Juniper features to enhance failover convergence, often referred to as BGP-PIC (Prefix-Independent Convergence). This set of features...
As a revolutionary multicast technology that allows efficient replication without requiring per-tree states in the network, Bit Index Explicit Replication (BIER) is the perfect solution for multicast in SR networks. This article explains BIER technology and its implementation/deployment...
Key applications of BGP Classful Transport (BGP-CT), including path-diversity across multiple ASes, multi-AS paths that take into account sovereignty constraints, and paths that achieve the minimum end-to-end latency across ASes. Introduction Color-based transport has been used within...
Another use case for link slicing: instead of data plane identifiers, control plane identifiers are used. Control plane protocols exchange the information that allows to classify packets to link slices. Introduction The Link Slicing with MPLS and SRv6 Underlays blog post discussed the...
BGP CT interoperability tests between Junos, Junos Evo and FreeRTR routers conducted in Berlin during the EANTC2023 event in March 2023. Introduction The BGP Classful Transport tests have been carried out in Berlin during the EANTC2023 interop event and included: Junos router:...
The guaranteed link slicing feature, using MPLS and SRv6 as underlay transport. Link slicing is a way to share physical bandwidth on links between multiple tenants, and guaranteed means providing minimum (guaranteed) bandwidth per tenant in case of...
Layer 3 Virtual Private Network Inter-AS option using SRv6 as underlay transport on MX and ACX7000 routers. Introduction This is the 5th blog post in the series of SRv6 blogs. This blog post is co-authored by Krzysztof Szarkowicz and Rajesh M...
Mapping modern and legacy services to colored MPLS paths, achieving business differentiation. Introduction People say there are no greenfield service providers (SPs). Some networks grow organically, some by acquisitions and merges. Growth takes time, and technology does not stay idle –...
JUNOS 22.3 introduced several changes in the SRv6 infrastructure, this article covers them in details. Introduction This is the 4th blog in the series of SRv6 blogs. It discusses the SRv6 infrastructure changes introduced with Junos...
