6.10.2.32. neighbor filter-list
This command is used to filter advertisements to or from a specific neighbor according to the advertisement’s
AS path. Only a single AS path list can be configured in each direction for each neighbor. If you invoke the
command a second time for a given neighbor, the new AS path list number replaces the previous AS path list
number.
If you assign a neighbor filter list to a nonexisted AS path access list, all routes are filtered.
Filtering for IPv6 is independent of filtering configured for IPv4. If an UPDATE message includes both IPv4 and
IPv6 NLRI, it could be filtered for IPv4 but accepted for IPv6 or vice versa.
To unconfigure neighbor filter lists, use the no form of this command.
Format neighbor {<ipv4-address> | <ipv6-address> [interface {<slot/port> | vlan {1-4093}}] | autodetect

no neighbor {<ipv4-address> | <ipv6-address> [interface {<slot/port> | vlan {1-4093}}] | autodetect
