M5300, M6100, and M7100 Series ProSAFE Managed Switches no address-family ipv6 Use the no address-family ipv6 command to clear all IPv6 address family configuration. Format Mode no address-family ipv6 BGP Router Config aggregate-address To configure a summary address for BGP, use the aggregate-address command in Router Configuration mode. 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. To be considered a match for an aggregate address, a prefix must be more specific (i.e. have a longer prefix length) than the aggregate address. A prefix whose prefix length equals the length of the aggregate address is not considered a match. When BGP originates a summary address, it installs a reject route in the common routing table for the summary prefix. Any received packets that match the summary prefix, but not a more specific route, match the reject route and are dropped. BGP accepts up to 128 summary addresses for each address family. Default Format Mode 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. aggregate-address {address mask | ipv6-prefix/pfx-len} [as-set] [summary-only] BGP Router Config Parameter Description address mask Summary IPv4 prefix and mask. The default route (0.0.0.0 0.0.0.0) cannot be configured as an aggregate-address. The mask cannot be a 32-bit mask (255.255.255.255). The combination of prefix and mask must be a valid unicast destination prefix. ipv6-prefix/pfx-len Summary IPv6 prefix and prefix length. The range for prefix length is 1 to 127. as-set (Optional) Normally, the aggregate is advertised with an empty AS path and the ATOMIC_AGGREGATE attribute. If the as-set option is configured, then the aggregate is advertised with a nonempty AS_PATH. If the AS_PATH of all contained routes is the same, then 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 (Optional) When the summary-only option is given, the more-specific routes within the aggregate address are not advertised to neighbors.
