Default Level

Usage Guidelines

source applies to prefix, prefix-ToS, source prefix, and source prefix-ToS modes.

destination applies to prefix, prefix-ToS, destination prefix, and destination prefix-ToS modes.

The system takes the larger mask between the mask in the FIB table and the configured mask. If the aggregation mask is not configured, you can aggregate streams based on the mask in the FIB table.

Example

# Configure the length of the source prefix aggregation mask to 24.

<sysname> system-view
[sysname] ip netstream aggregation source-prefix
[sysname-aggregation-srcpre] mask source minimum 24
