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
