neighbor filter-list

Specifies a filter list to be applied to updates from or to the specified neighbor.

Syntax

neighbor { ip-address | ipv6-address | peer-group-name } filter-list ip-prefix-list-name { in | out }

no neighbor { ip-address | ipv6-address | peer-group-name } filter-list ip-prefix-list-name { in | out }

Command Default

No filter list is applied.

Parameters

ip-address: IPv4 address of the neighbor.
ipv6-address: IPv6 address of the neighbor.
peer-group-name: Peer group name configured by the neighbor peer-group-name command.
ip-prefix-list-name: Name of the filter list. The name must be between 1 and 63 ASCII characters in length.
in: Specifies that the list is applied on updates received from the neighbor.
out: Specifies that the list is applied on updates sent to the neighbor.

Modes

BGP address-family IPv4 unicast configuration mode

BGP address-family IPv6 unicast configuration mode

BGP address-family IPv4 unicast VRF configuration mode

BGP address-family IPv6 unicast VRF configuration mode

Usage Guidelines

Use the no form of the command to remove the association of filter-list from peer or peer-group.

Examples

This example specifies that filter list “myfilterlist” be applied to updates to a neighbor with the IP address 10.11.12.13 for the default VRF.

device# configure terminal 
device(config)# router bgp
device(config-bgp-router)# address-family ipv4 unicast
device(config-bgp-ipv4u)# neighbor 10.11.12.13 filter-list myfilterlist out

This example specifies that filter list “2” be applied to updates from a neighbor with the IPv6 address 2001:2018:8192::125 for the default VRF.

device# configure terminal 
device(config)# router bgp
device(config-bgp-router)# address-family ipv6 unicast
device(config-bgp-ipv6u)# neighbor 2001:2018:8192::125 filter-list 2 in

This example specifies that filter list “2” be applied to updates from a neighbor with the IPv6 address 2001:2018:8192::125 for VRF instance "red".

device# configure terminal 
device(config)# router bgp
device(config-bgp-router)# address-family ipv6 unicast vrf red
device(config-bgp-ipv6u-vrf)# neighbor 2001:2018:8192::125 filter-list 2 in

This example specifies that filter list 2 be applied to updates from a neighbor with the IPv4 address 20.0.0.1 for the VRF instance red.

device# configure terminal
device(config)# router bgp
device(config-bgp-router)# address-family ipv6 unicast vrf red
device(config-bgp-ipv6u-vrf)# neighbor 20.0.0.1 filter-list 2 in
