The Business Problem: Overview
Outage Detection
Complexity of IP/MPLS networks e.g.LSP Black holes in MPLS core
Network Configuration changes …typically cause 50% of network outages
Access circuit issues –typically 70-80% ofcustomer support calls
Customer network problems – all toooften “MPLS VPN outage” root cause
Need for MPLS skills on the Helpdesk
NOC Organizational “hand-overs”
Front-line helpdesk -> Level 2 support –>Level 3 support/Design Engineering)

Fault in MPLS CoreLSP “blackhole” (Real Life) Example
LSP
Real life example: Fault occurs on line
card, partial failure, forwarding ASIC
affected, traffic “disappears”. No
alarm generated. “Blackhole”

How you find fault location in other vendor’snetworks … or Pre Cisco IOS 12.0(27)S
LSP
The fault is here … but you had to check
70 out of 100 P/PE nodes before you
found the location of this “black hole”
… but what is root cause?And this one …
And this oneThen this one
Check this node,
using MIBs & CLI
Real Life Example … Took 17 Hours of Outage to Find and Diagnose
