Background

• Current configuration of MPLS TE via the most popular Cisco CLI

• Can very soon become cumbersome for large networks

–120-200 routers fully meshed

–Largest TE customer has nearly 8,000 tunnels

–Configuration of Guaranteed Bandwidth, L2VPN (pt-to-pt), QoS

• We need a network wide configuration/visualization tool

TE Tunnel Configuration

• Config Example

–Need to execute x commands on the CLI

–Need to map traffic onto the tunnel

–Verify the tunnel operation

–Close the case

• What happens when a tunnel fails?

–Wait till you get an error message

–You get the idea…

• Can I reduce this process to just a few clicks?

• “...only a few clicks away…”

Tunnel Builder PRO - Planned

• Backup Route Generator (BRG)

–Used in conjunction with MPLS Fast ReRoute Link and Node Protection as well as DiffServ aware Traffic Engineering to provide Bandwidth Protection across a SP Cloud.

–Bandwidth Protection Module provides computation of Backup Paths for Guaranteeing Bandwidth based SLAs

• Backup Tunnel Provisioning – MPLS FRR Link and Node Protection

• Configure and display Shared Risk Link Group (SRLG) membership

• Provides complete protection for subpool for DS-TE

• Provide bandwidth protection in accordance with a specified overbooking factor

• Allows protecting traffic by one or more tunnels

• Analyze bandwidth & propagation delay protection of nodes, links, SRLGs

• Recommend/display/configure FRR backup tunnels for bandwidth protection

Radar Functionality

• Configuration & Modification of Tunnels–Policy Routing

–Password Protecting Tunnel from deletion

–Creation of tunnels using templates(Template selection, saving of templates)

–Enable TE on all routers and links/interfaces if source and destination is specified

• SAA per Tunnel basis–Packet Loss

–Correlate SAA path with PATH option

• Display–List Tunnels that can be pre-empted given any source-destination pair, bandwidth and the priority
