ospf process-id: Filters OSPF routes to be advertised that are from a specified OSPF 
process. The process-id argument is in the range 1 to 65535.

rip process-id: Filters RIP routes to be advertised that are from a specified RIP 
process. The process-id argument is in the range 1 to 65535.

static: Filters static routes to be advertised.

Use the filter-policy export command to specify to filter all or certain types of 
routes to be advertised.

Use the undo filter-policy export command to remove the configuration.

If you specify no routing protocol parameters for the filter-policy export 
command, all routes to be advertised will be filtered.

By default, MP-BGP does not filter routes to be advertised.

Only routes that survive the filtering are advertised by MP-BGP.

# In BGP-VPNv4 subaddress family view, specify to filter routes to be advertised by 
MP-BGP using ACL 2555.
