Volume 4-Layer 3 Configurations / Chapter 30-Border Gateway Protocol (BGP) BGP Configuration commands The as-set parameter creates an aggregate entry advertising the path for this route, consisting of all elements contained in all paths being summarized. Use the as-set parameter to reduce the size of path information by listing the AS number only once, even if it was included in multiple paths that were aggregated. The as-set parameter is useful when the aggregation of information results in incomplete path information. Command Explanation enable [privilege LEVEL] configure terminal router bgp AS-NUMBER Enter privileged EXEC mode. Enter Global configuration mode. Enter the following information to configure BGP routing process and enter into BGP configuration mode. aggregate-address NETWORK-NUMBERS/SUBNET- Enter the following information to configure BGP LENGTH [summary-only][as-set] aggregate entries.

BGP networks can be learned from connected routes, from dynamic routing, and from static route sources. Use this command to specify a network as local to this autonomous system and adds it to the BGP routing table. For exterior protocols the network command controls which networks are advertised. Interior protocols use the network command to determine where to send updates. The maximum number of supported network entries is project dependent. The BGP will advertise a network entry if the router has the route information for this entry if synchronize state is enabled. DGS-6600 Configuration Guide 298
