filter-policy export Syntax
filter-policy { acl-number | ip-prefix ip-prefix-name } export [ protocol ]
undo filter-policy { acl-number | ip-prefix ip-prefix-name } export [ protocol ]
View
IPv4 multicast sub-address family view
Parameter
acl-number: Number of ACL used in matching the destination address domain of
routing information, in the range of 2000 to 3999.
ip-prefix-name: Name of the IP prefix used in matching the destination address
domain of routing information, in the range of 1 to 19.
Protocol: Protocol specifing which kind of routing information shall be filtered out,
with options currently available include direct, ospf, ospf-ase, ospf-nssa, rip,
is-is and static.
Description
Use the filter-policy export command to set to filter the advertised routes. Only
those pass through the filter can be advertised by BGP.
Use the undo filter-policy export command to cancel route filtering.
By default, filtering the advertised routes is not enabled.
The command affects route advertising by BGP. If you specify the protocol
parameter, the router only filters the routes with the specified protocol imported,
without influence on the routes importing other protocols. Otherwise, the router
filters the routes importing any protocols.
Example
# Filter all BGP-advertised routes using ACL 2000.
<SW8800> system-view
