QoS/MQC Support for MTR
12.2(33)SRB
This feature enables MTR traffic classification. Traffic
classification is used to associate different classes of traffic
with different topologies when multiple topologies are
configured on the same router. A subset of DSCP bits is
used to encode classification values in the IP packet header
and mark the packet for classification. When MTR traffic
classification is enabled, MTR is activated and ready for the
routing protocols to start contributing to the topologies.

SNMP Support for MTR
12.2(33)SRB
Context-based Simple Network Management Protocol
(SNMP) functionality has been integrated into Cisco IOS
software and can be used to support MTR. SNMP support
for MTR leverages context-based SNMP to extend support
for existing MIBs from representing the management
information for just the base topology to representing the
same information for multiple topologies.
