    Router Features

    Interior Gateway Protocols (IGP)

    • Modeling of OSPF, ISIS, EIGRP, IGRP, and RIP routing protocols
    • OSPF two-layer hierarchy (backbone area and areas off of the backbone area)
    • Routing metric modification by modifying variables like the cost, reference bandwidth, interface bandwidth, and delay, according to each routing protocol’s metric calculation formula.

    Equal Cost Multiple Paths (ECMP)

    • Path analysis displaying ECMP routes between two nodes
    • ECMP report listing ECMP routes in the network
    • Load balancing by splitting flows into subflows with equal cost paths.

    Static Routes

    • Extraction of static route tables
    • What-if studies upon adding or modifying static routes

    Policy Based Routes (PBR)

    • Extraction of PBR details (access list, policy route map)
    • What-if analyses by modifying the policy to use on an interface

    Border Gateway Protocol (BGP)

    • Extraction of BGP speakers, AS numbers, Peering points for both IBGP and EBGP, Route Reflectors, BGP communities, Weight, Local preference, Multi-exit discriminator, AS_PATH, and BGP next hop from router config files
    • Key integrity checks are performed such as finding BGP unbalanced neighbors and checking IBGP mesh connectivity
    • Implementation of the BGP route selection rules and bottleneck analysis to troubleshoot routing failures
    • BGP attribute modification for what-if studies
    • BGP map logical view of EBGP and IBGP connections

    Virtual Private Networks (IP VPN)

    • Modeling of MPLS VPNs such as L3 VPN, L2 Kompella, L2 Martini, L2 CCC, and VPLS
    • VPN extraction from router configuration files
    • VPN topology display and reports
    • VPN-related integrity checks
    • Design and modeling of VPN via a VPN Wizard
    • Adding of VPN traffic demands
    • VPN monitoring and diagnostics (when used in conjunction with the Online Module)

    Class of Service (CoS)

    • Extract of CoS classes and policies from router config files
    • Create and modify CoS classes and policies and assign policies for link interfaces.
    • View Link and Demand CoS reports and Link Load reports by CoS Policy

    Multicast

    • Create, view and modify multicast groups
    • Create multicast demands and analyze their paths.
    • PIM modes including sparse mode, dense mode, bidirectional PIM, and SSM

    VoIP

    • Define H.323 media gateways/gatekeepers, SIP user agents/servers, and codecs.
    • Perform a call setup path analysis and view a report of call setup delays.
    • Use the traffic generation wizard to generate traffic starting from Erlangs

    OSPF Area Design

    Design of the backbone network based on the following settings:

    • Specify which nodes to use as gateways and the areas accessible to this gateway
    • Specify administrative weights to be used for designed links from the Admin Weight feature

    Multi-Protocol Label Switching (MPLS) Tunnels for Traffic Engineering

    Path Placement

    • Routing of LSP (label switched path) tunnels over physical links
    • Routing of traffic demand flows (forwarding equivalence class, or, FEC) over LSP tunnels and links

    Modification

    • Modification of LSP tunnel preferred/explicit routes and media requirements (Bandwidth constraints, QoS requirements, Priority and preemption, affinity/mask and include-any/include-all/exclude admin-groups)
    • Addition of Secondary/Standby Routes

    Net Grooming

    • Network grooming of tunnel paths

    Configlet Generation

    • Configlets created based on added and modified tunnels
    • Templates can be specified

    Path Diversity Design

    • Design primary and secondary/standby tunnel paths to be link-diverse, site-diverse, or facility-diverse.
    • View or tune the resulting paths.

    Fast Reroute (FRR)

    • Specification of tunnels requesting FRR protection and FRR backup tunnels.
    • Simulation of routing according to FRR during link failure
    • Design of FRR backup tunnels for LSP tunnels requesting FRR protection according to site or facility diversity requirements

    Inter-Area MPLS-TE

    • Design LSP tunnels between different OSPF areas for multi-area networks.

    DiffServ TE Tunnels

    • Create and model Juniper Networks’ single-class and multi-class LSPs.
    • Configure bandwidth model (RDM, MAM) and bandwidth partitions.
    • Define scheduler maps (CoS policies) and assign them to links.
