neighbor prefix-list

neighbor { ipAddress | ipv6Address | peerGroupName } prefix-list
prefixListName { in | out }

no neighbor { ipAddress | ipv6Address | peerGroupName } prefix-list
[ prefixListName ] { in | out }

Command introduced before JUNOSe Release 7.1.0.
ipv6Address variable added in JUNOSe Release 8.0.0.

Assigns an inbound or outbound prefix list. The no version removes the prefix list.

ipAddress—IP address of BGP neighbor
ipv6Address—IPv6 address of BGP neighbor
peerGroupName—Name of a BGP peer group. If you specify a BGP peer group by using the peerGroupName argument, all the members of the peer group inherit the characteristic configured with this command, unless it is overridden for a specific peer.
prefixListName—Name of a BGP prefix list
in—Assigns prefix list to incoming routes (inbound policy)
out—Assigns prefix list to outgoing routes (outbound policy); you cannot configure a member of a peer group to override the inherited peer group characteristic for outbound policy
