Layer 3 Routing Commands 1284
neighbor allowas-in
Use the neighbor allowas-in command to accept prefixes even if local ASN is
part of the AS_PATH attribute. Use the no form of the command to disable
acceptance of prefixes if the local ASN is part of the AS_PATH.
Syntax
neighbor { ip-address | ipv6-address [ interface interface-name ] |
autodetect
interface vlan vlan-id } allowas-in count
no neighbor { ip-address | ipv6-address [ interface interface-name ] |
autodetect
interface interface-id } allowas-in
• ip-address — The neighbor’s IPv4 address.
•
ipv6-address [ interface interface-name ] — The neighbor’s IPv6 address.
If the neighbor’s IPv6 address is a link local address, the local interface
must also be specified.
•
autodetect interface interface-id — The VLAN routing interface on which
the neighbor’s link local IPv6 address is auto detected. Use the
vlan
keyword and a VLAN identifier.
•
allowas-in count — The maximum number of occurrences of the local
ASN allowed in the AS_PATH attribute received in the prefix updates. The
allowed range is <1-10>.
Default Configuration

AS_PATH attribute.
