Syntax neighbor {ip-address | ipv6-address [interface interface-id] | autodetect interface vlan vlan-id} local-as as-number no-prepend replace-as no neighbor {ip-address | ipv6-address [interface interface-id] | autodetect interface interface-id} local-as • interface-id-A routing interface identifier (VLAN interface). • 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. • local-as as-number - The AS number to advertise as the local AS in the AS PATH sent to the neighbor. The as-number is the router's autonomous system number in asplain format. Dell Networking BGP supports four byte AS numbers, in the range of 0-429496729. • no-prepend - The local-as is not prepended in the AS PATH received in the updates from this neighbor. • replace-as - Replace the router's own AS with the local-as in the AS PATH sent to the neighbor. Default Configuration No local-as is configured for any peer. Command Mode BGP Router Configuration mode, BGP Router VRF Configuration mode User Guidelines In typical data center deployments using CLOS networks, the peering is all external BGP between the BGP devices requiring an unique ASN for each router. Normally, the private BGP networks are expected to use private AS numbers. But, there are only 1024 private AS numbers in the standard 2-byte ASN. Layer 3 Routing Commands 1363
