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


  • Create, view and modify multicast groups

  • Create multicast demands and analyze their paths.

  • PIM modes including sparse mode, dense mode, bidirectional PIM, and SSM


  • 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 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.
