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

• 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.
