Parameters
acl-number: Specifies an IPv4 ACL by its number in the range of 2000 to 3999 to match routes by
destination.
acl6-number: Specifies an IPv6 ACL by its number in the range of 2000 to 3999 to match routes by
destination.
prefix-list prefix-list-name: Specifies an IPv4 prefix list by its name, a case-sensitive string of 1 to 63
characters, to match routes by destination.
prefix-list ipv6-prefix-name: Specifies an IPv6 prefix list by its name, a case-sensitive string of 1 to 63
characters, to match routes by destination.
protocol: Filters routes redistributed from the routing protocol. In BGP IPv4 unicast address family
view/BGP-VPN IPv4 unicast address family view/BGP VPNv4 address family view, it can be direct, isis,
ospf, rip, or static. In BGP IPv6 unicast address family view/BGP-VPN IPv6 unicast address family
view/BGP VPNv6 address family view, it can be direct, isisv6, ospfv3, ripng, or static.
process-id: Specifies a routing protocol by its ID in the range of 1 to 65535. In BGP IPv4 unicast address
family view/BGP-VPN IPv4 unicast address family view/BGP VPNv4 address family view, it is available
only when the protocol is isis, ospf, or rip. In BGP IPv6 unicast address family view/BGP-VPN IPv6
unicast address family view/BGP VPNv6 address family view, it is available only when the protocol is
isisv6, ospfv3, or ripng.
Usage guidelines
If a protocol is specified, this command filters only routes redistributed from the specified protocol. If no
protocol is specified, this command filters all advertised routes, including routes redistributed from IGP,
injected by the network command, and learned from BGP peers.
The following guidelines apply when you use an ACL in the command:
To filter routes with a specific destination address, use a basic ACL (2000 to 2999) or an advanced
•
ACL that contain rules defined with the rule [ rule-id ] { deny | permit } ip source sour-addr
sour-wildcard command.
To filter routes with a specific destination address and mask, use an advanced ACL that contains
•
rules defined with the rule [ rule-id ] { deny | permit } ip source sour-addr sour-wildcard destination
dest-addr dest-wildcard command.
If an ACL is used, BGP advertises only routes that match a permit rule in the ACL.
