Syntax
neighbor { ip-address | ipv6-address [ interface interface-id ] | autodetect

• interface-id — A routing interface identifier beginning with the VLAN
keyword.
• ip-address — The neighbor’s IPv4 address.
• ipv6-address [ interface interface-id ] — 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>.
