29.11 Configuring Route Aggregate for
BGP
For the BGP-4 supports CIDR, it allows to create the aggregate table item to reduce the
BGP route table. Of course, only when there is valid path within the aggregate scope, the
BGP aggregate table item will be added to the BGP route table.
To configure the BGP route aggregate, execute the following operations in the BGP
configuration mode:
Command
Meaning
Router(config-router)# aggregate-address
address mask
(Optional) Configure the aggregate address.
Router(config-router)# aggregate-address
address mask as-set
(Optional) Configure the aggregate address, and
remain the AS path information of the path within the
scope of the aggregate address.
Router(config-router)# aggregate-address
address mask summary-only
(Optional) Configure the aggregate address and only
advertise the aggregated path.
Router(config-router)# aggregate-address
address mask as-set summary-only
(Optional) Configure the aggregate address, and
remain the AS path information of the path within the
scope of the aggregate address. At the same time,
only the aggregated path is advertised.
Use the no mode of above commands to disable the configured content.
Caution
By default, the BGP will advertise all path information both before and after
aggregation. If you only hope to advertise the aggregated path
information, use the aggregate-address summary-only command.
29.12 Configuring Route Reflector for
BGP
To speed up the convergence of the route information, all BGP Speakers within one AS will
usually establish the full connection relationship (The adjacent relationship is established
between any two BGP Speakers). If the BGP Speakers within the AS is too much, it will
increase the resource overhead of the BGP Speakers, raise the workload and complexity of
the task assignment for the network manager and reduce the network expansibility capacity.
For this reason, two measures such as the route reflector and AS confederation are
proposed to reduce the connections of the IBGP peers within AS.
The route reflector is a measure to reduce the connections of the IBGP peer within the AS.
One BGP Speaker is set as the route reflector, which divides the IBGP peer within this AS
into two types, such as client and non-client.
