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
• Modification
• Net Grooming
• Configlet Generation
• Path Diversity Design

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.
