maybe you can try with the command
xtocid1108634BM_26364BM_1019419neighbor maximum-prefix
To control how many prefixes can be received from a neighbor, use the
neighbor maximum-prefix router configuration command. To disable this
function, use the no form of this command.
BM_1019421neighbor {ip-address | peer-group-name} maximum-prefix maximum
[threshold][warning-only]
no neighbor {ip-address | peer-group-name} maximum-prefix maximum
Syntax Description
ip-address
IP address of the neighbor.
peer-group-name
Name of a BGP peer group.
maximum
Maximum number of prefixes allowed from this neighbor.
threshold
(Optional) Integer specifying at what percentage of maximum the router
starts to generate a warning message. The range 1 to 100; the default is 75
(percent).
warning-only
(Optional) Allows the router to generate log message when the maximum is
exceeded, instead of terminating the peering.
Defaults
Disabled; there is no limit on the number of prefixes.
Command Modes

This command was introduced.
Usage Guidelines
This command allows you to configure a maximum number of prefixes a BGP
router is allowed to receive from a peer. It adds another mechanism (in
addition to distribute lists, filter lists, and route maps) to control
prefixes received from a peer.
When the number of received prefixes exceeds the maximum number configured,
the router terminates the peering (by default). However, if the keyword
warning-only is configured, the router instead only sends a log message, but
continues peering with the sender. If the peer is terminated, the peer stays
down until the clear ip bgp command is issued.
Examples
The following example sets the maximum number of prefixes allowed from the
neighbor at 129.140.6.6 to 1000:
router bgp 109
network 131.108.0.0
neighbor 129.140.6.6 maximum-prefix 1000

look at your route map or filter list configs.
you can always set them using only filter-list. why not advertise
none to him and just point default to you? your client is not multi-homing
isn't he? 400 routes + default is the same as default only.
