Create Bgp Aggregate_Address [<Network_Address> | Ipv6 <Ipv6_Networkaddr>] {Summary_Only; As_Set - D-Link xStack DGS-3620 Reference Manual

xStack® DGS-3620 Series Layer 3 Managed Stackable Gigabit Switch CLI Reference Guide
Using the aggregate_address command with no keywords will create an aggregate entry in the
BGP routing table, if any more specific BGP routes are available that fall within the specified range.
The aggregate route will be advertised as coming from your Autonomous System and will have the
atomic aggregate attribute set to indicate that information might be missing. That is, the original AS
path associated with more specific routes will be lost. The atomic aggregate attribute is set unless
you specify the as_set keyword.
Using the as_set keyword will create an aggregate entry, but the path advertised for this route will
include an AS set consisting of all AS that are contained in all paths that are being summarized.
Do not use continually withdrawn and updated as autonomous system path reachability
information for the summarized routes changes.
Using the summary_only keyword will create an aggregate route but suppresses advertisements of
more specific routes to all neighbors. If you want to suppress only advertisements to certain
neighbors, you may use the neighbor prefix_list command.
Format
create bgp aggregate_address [<network_address> | ipv6 <ipv6_networkaddr>]
{summary_only | as_set}
Parameters
<network_address> - Specifies the IPv4 network address that will be aggregated.
ipv6 – Specifies the IPv6 network address that will be aggregated.
<ipv6_networkaddr> - Enter the IPv6 network address that will be aggregated here.
summary_only - (Optional) Specifies that more specific routes will not be advertised.
as_set - (Optional) Generates an Autonomous System set path information.
Restrictions
Only Administrators, Operators and Power-Users can issue this command. (EI Mode Only
Command)
Example
To create an aggregate route of which the network address is 10.0.0.0/8, suppress more-specific
routes:
DGS-3620-28PC:admin#
Command: create bgp aggregate_address 10.0.0.0/8 summary_only
Success.
DGS-3620-28PC:admin#
12-9 delete bgp aggregate_address
Description
This command is used to delete an aggregate entry in a Border Gateway Protocol (BGP) database.
