Parameter
acl-number: Number of IP access control list.
ip-prefix-name: Name of ip prefix list, containing 1 to 19 characters.
protocol: Routing protocol, specifying a protocol whose routing information is filtered.
Currently, the routing protocols includes direct, ospf, ospf-ase, ospf-nssa, rip, isis,
and static.
process-id: Routing protocol process ID, in the range of 1 to 65535. This argument is
valid only when the protocol is ospf.
Description
Use the filter-policy export command to filter the advertised routes and only the
routes passing the filter can be advertised by BGP.
Use the undo filter-policy export command to cancel the filtration to the advertised
routes.
By default, filtration to the received routing information is not configured.
If a value is specified for the protocol argument, only the imported route generated by
the specified protocol is filtered and the imported routes generated by other protocols
are not affected. If no value is specified for the protocol argument, the imported route
generated by any protocol will be filtered.
Example
