no aggregate-address {ipv4-prefix mask | ipv6-prefix/prefix-length} [as-set] [summary-only] • ipv4-prefix mask-A summary prefix and mask in dotted-quad notation. The default route (0.0.0.0 0.0.0.0) cannot be configured as an aggregateaddress. The mask cannot be a 32-bit mask (255.255.255.255). The combination of prefix and mask must be a valid IPv4 unicast destination prefix • ipv6-prefix-An IPv6 network prefix. This argument must be in the form documented in RFC 2373 where the address is specified in hexadecimal using 16-bit values between 0x00 and 0xff and separated by colons. Counters are cleared only for the matching prefixes. • prefix-length-The length of the IPv6 prefix given as part of the ipv6prefix. This is required if a prefix is specified. A decimal value in the range 0 to 128 that indicates how many of the high-order contiguous bits of the address comprise the prefix (the network portion of the address) in /length format. A slash must precede the decimal value in /length format. • as-set- If the as-set option is configured, the aggregate is advertised with a non-empty AS_PATH. (Normally, the aggregate is advertised with an empty AS path and the ATOMIC_AGGREGATE attribute.) If the AS_PATH of all contained routes is the same, the AS_PATH of the aggregate is the AS_PATH of the contained routes. Otherwise, if the contained routes have different AS_PATHs, the AS_PATH attribute includes an AS_SET with each of the AS numbers listed in the AS PATHs of the aggregated routes. If the as-set option is not configured, the aggregate is advertised with an empty AS_PATH. • summary-only - When specified, the more-specific routes within the aggregate address are not advertised to neighbors. Default Configuration No aggregate addresses are configured by default. Unless the options are specified, the aggregate is advertised with the ATOMIC_AGGREGATE attribute and an empty AS path, and the more specific routes are advertised along with the aggregate.
