Cisco Cisco IOS Software Release 12.2(33)SXH

In Cisco IOS Release 12.2(33)SXH, the Cisco IOS Software Modularity feature has been extended to 
include Multiprotocol Label Switching (MPLS) Virtual Private Networks (VPNs). Through software 
infrastructure enhancements, the Cisco IOS Software Modularity: MPLS Layer 3 VPNs feature reduces 
both planned and unplanned downtime and boosts operational efficiency. You can restart, upgrade, and 
patch modularized components and processes without interrupting service. 

Identifying and fixing faults and failures is also easier, because you can isolate components and 
processes. The software modularity capabilities integrate with and make use of High Availability (HA) 
features already in place.

Your Cisco IOS software release may not support all of the features documented in this module. To reach
