The vRtrInstanceAggregationTable is the list of configured
VRtr aggregations and their operational status information.
Specifies the route aggregates that should be generated
into the virtual router if at least one contributing route
(more specific) is learned.
A route could match multiple aggregate statements.
For instance, with the following entries:
aggregate 10.0.0.0/8
aggregate 10.1.0.0/16
If the route 10.1.1.0/24 is learned, both aggregates would be
generated.
This table was obsoleted in release 7.0. It is replaced with the
vRtrInetInstAggrTable to support ipv6 addresses.
