Defining Neighbor Distribute Lists

A neighbor distribute list is a list of BGP4 address filters or ACLs that filter the traffic to or from a neighbor. To
configure a neighbor distribute list, use either of the following methods.
USING THE CLI
To configure a distribute list that uses ACL 1, enter a command such as the following:
BigIron(config-bgp-router)# neighbor 10.10.10.1 distribute-list 1 in
This command configures the Layer 3 Switch to use ACL 1 to select the routes that the Layer 3 Switch will accept
from neighbor 10.10.10.1.
Syntax: neighbor <ip-addr> distribute-list <name-or-num> in | out
The <ip-addr> parameter specifies the neighbor.
The <name-or-num> parameter specifies the name or number of a standard, extended, or named ACL.
The in | out parameter specifies whether the distribute list applies to inbound or outbound routes:
• in – controls the routes the Layer 3 Switch will accept from the neighbor.
• out – controls the routes sent to the neighbor.
