export: Applies the filter to routes advertised to the specified peer/peer group.

import: Applies the filter to routes received from the specified peer/peer group.

Use the peer ip-prefix command to reference an IP prefix list to filter routes 
received from or advertised to a peer or peer group.

Use the undo peer ip-prefix command to remove the configuration.

By default, no IP prefix list is specified.

# In BGP view, use the IP prefix list list 1 to filter routes advertised to the peer 
group test.

group-name: Name of a peer group, a string of 1 to 47 characters.

ip-address: IP address of a peer.

Use the peer keep-all-routes command to save original routing information 
from a peer or peer group, even routes that failed to pass the inbound policy (if 
configured).

Use the undo peer keep-all-routes command to disable this function.

By default, the function is not enabled.

# In BGP view, save routing information from peer 131.100.1.1.
