• Configure Router A to perform NetStream aggregation in the modes of AS, protocol-port,
source-prefix, destination-prefix and prefix. Use version 8 export format to send the aggregation
data of different modes to the destination address at 4.1.1.1, with UDP port 2000, 3000, 4000,
6000, and 7000 respectively.
NOTE:
All the routers in the network are running EBGP. For more information about BGP, see Layer 3—IP Routing
Configuration Guide.
