Border Gateway Protocol Ipv4 (Bgpv4) - Dell MXL 10GbE Reference Manual

Border Gateway Protocol IPv4 (BGPv4)

For detailed information about configuring BGP, refer to the BGP chapter in the Dell Networking OS
Configuration Guide.
This chapter contains the following sections:
• BGPv4 Commands
• MBGP Commands
• BGP Extended Communities (RFC 4360)
BGP IPv6 Commands are listed in the following sections:
• IPv6 BGP Commands
• IPv6 MBGP Commands
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.
