neighbor remove-private-as

Use this command to filter the private AS in the routes advertised
to neighbors or neighbor peers. Disable this function with the no
form of this command.
Router configuration and address family configuration
neighbor [<ipv4-address>|<ipv6-address>|<peer-group-nam
e>] remove-private-as
no neighbor [<ipv4-address>|<ipv6-address>|<peer-group-na
me>] remove-private-as
<ipv4-address>
<ipv6-address>
<peer-group-name>
This command is enabled by default, that is, the private AS number
will be filtered out.
Since the quantity of AS numbers is limited, the private AS number
can be used to divide a large AS into multiple areas connected by
EBGP. The private Ass will be filtered in the access to the Internet.
In this way, the inside is transparent for the Internet.
The range of the private AS is 64512~65535.
Tip:
When a confederation is configured, since the peers in the confed-
eration are mostly marked as "private as", it may cause the route
loopback if the private AS is removed. As a result, this command
is ineffective to the EBGP peers inside the confederation.
This example describes how to filter the private AS in routes ad-
vertised to the BGP neighbor 2000::1.
ZXR10(config)#router bgp 1
ZXR10(config-router)#address-family ipv6
ZXR10(config-router)#neighbor 2000::1 remove-private-as
