10 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. NOTE: For more information about configuring the border gateway protocol (BGP), see the BGP section in the Dell Networking OS Configuration Guide. 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: Dell Networking OS 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: Dell Networking OS 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 Dell Networking OS Configuration Guide. address-family Enable the IPv4 multicast or the IPv6 address family. Syntax Parameters address-family [ipv4 {multicast | vrf vrf-name} | ipv6 unicast [vrf vrf-name]] ipv4 multicast ipv4 vrf vrf-name Enter the keyword ipv4 followed by the keyword multicast to enable BGPv4 multicast mode. Enter the keyword ipv4 followed by the keyword vrf and then the name of the VRF to enable VRF mode. 406 Border Gateway Protocol

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.

NOTE:

For more information about configuring the border gateway protocol (BGP), see the

BGP

section in the

Dell Networking OS Configuration Guide

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:

Dell Networking OS 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:

Dell Networking OS 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

Dell Networking OS Configuration

Guide
