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-topt), 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
