BGPv4 Commands
Border gateway protocol (BGP) is an external gateway protocol that transmits interdomain routing information within and
between autonomous systems (AS).
BGP version 4 (BGPv4) supports classless interdomain routing (CIDR) and the aggregation of routes and AS paths. Basically,
two routers (called neighbors or peers) exchange information including full routing tables and periodically send messages to
update those routing tables.
NOTE:
Dell Networking OS Version 7.7.1 supports 2-Byte (16-bit) and 4-Byte (32-bit) format for autonomous system
numbers (ASNs), where the 2-Byte format is 1-65535 and the 4-Byte format is 1-4294967295.
NOTE: Dell Networking OS Version 8.3.1.0 supports dotted format as well as the traditional plain format for AS numbers.
Display the dot format using the show ip bgp commands. To determine the comparable dot format for an ASN from a
traditional format, use ASN/65536. ASN%65536. For more information about using the 2–Byte or 4-Byte format, refer to
the Dell Networking OS Configuration Guide.
