12-26 Config Bgp Neighbor Route_Reflector_Client - D-Link xStack DGS-3620 Reference Manual

xStack® DGS-3620 Series Layer 3 Managed Stackable Gigabit Switch CLI Reference Guide

12-26 config bgp neighbor route_reflector_client

Description
This command is used to configure the BGP's neighbor of the route reflector client. When the route
reflector client is defined and the router reflection is enabled, the BGP router will act as the route
reflector. The reflector and its client form a cluster. In a cluster, all the members must be iBGP
connections with the reflector and vice versa. The reflector is the representative of the cluster. For
the reflector, the iBGP connection is established by the "create bgp neighbor" command and the
corresponding neighbor must be specified as the client by this command. For the client, the iBGP
connection is established by the "create bgp neighbor" command.
When the router is in reflection mode, the router will exchange information with client neighbors in
the reflection way and with the remaining neighbor in the ordinary way.
When the router is in non-reflection mode, the router will exchange information with all the
neighbors in the non-reflection way.
An AS can have multiple clusters, and a cluster can have more than one reflector for redundancy
purposes.
By default, if both the IPv4 unicast and IPv6 unicast options are not specified, the setting is for the
IPv4 unicast address family.
Format
config bgp neighbor route_reflector_client [<ipaddr> | <ipv6addr> | peer_group
<peer_group_name 16>] {[ipv4 | ipv6] unicast} state [enable | disable]
Parameters
<ipaddr> - Specifies the IPv4 address of the neighbor to be configured.
<ipv6addr> - Specifies the IPv6 address of the neighbor to be configured.
peer_group - Specifies the peer group to be configured.
<peer_group_name 16> - Enter the peer group name here. This name can be up to 16
characters long.
ipv4 unicast - Specifies to configure the IPv4 unicast address family.
ipv6 unicast - Specifies to configure the IPv6 unicast address family.
state - The specified neighbor will become the router reflector client. By default, this state is
disabled.
enable - Specifies that the neighbor will become the router reflector client.
disable - Specifies that the neighbor will not become the router reflector client.
