Router Configuration.
Level: 8. (EI Mode Only Command)
This command is used to enter the IPv4 VPN address family mode. The BGP peers
activated in this mode are used to exchange VPN IPv4 routing information.
Please note that only iBGP peers are supported in this address family now.
To exit from this address-family configuration mode, use the exit-address-family
command.
This example shows how to enter the VPNv4 address family and activate a BGP
peer.
Specifies the network address and the sub-network mask that BGP will aggregate.
For example, the format of NETWORK-ADDRESS can be 10.9.18.2/8.
(Optional) Filters all more-specific routes from updates.
(Optional) Generates autonomous system set path information.
None.
Router Configuration.
Level: 8. (EI Mode Only Command)
Aggregates are used to minimize the size of routing tables. Aggregation combines
the characteristics of several different routes and advertises a single route. The
aggregate-address command creates an aggregate entry in the BGP routing table if
any more-specific BGP routes are available in the specified range. Using the
summary-only parameter advertises the prefix only, suppressing the more-specific
routes to all neighbors.
Use the as-set parameter to reduce the size of path information by listing each AS
number only once, even if it was included in multiple paths that were aggregated.
The as-set parameter is useful when aggregation of information results in
incomplete path information.
You can verify your settings by entering the show ip bgp aggregate command.
This example shows how to propagate the network 172.0.0.0 and suppress a more
specific route called 172.10.0.0
