8 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 inter-domain 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 sent messages to update those routing tables. BGP is supported in the following: FTOS Version 9.0.0.0 8.3.7.0 8.1.1.0 7.8.1.0 7.7.1.0 pre-7.7.1.0 Platform Support Z9000 S4810 E-Series ExaScale S-Series C-Series E-Series TeraScale NOTE: For more information about configuring the border gateway protocol (BGP), refer to the BGP chapter in the FTOS Configuration Guide. This chapter contains the following sections: • BGPv4 Commands • MBGP Commands • BGP Extended Communities (RFC 4360) • IPv6 BGP Commands • IPv6 MBGP Commands BGP IPv4 Commands Border Gateway Protocol (BGP) is an external gateway protocol that transmits interdomain routing information within and between Autonomous Systems (AS). BGP 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: FTOS 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 to 65535 and the 4-byte format is 1 to 4294967295. NOTE: FTOS Version 8.3.1.0 supports dotted format as well as the traditional plain format for AS numbers. The dot format is displayed when 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- or 4-byte format, refer to the FTOS Configuration Guide. 329
