Usage guidelines
Using route reflectors can solve the issue brought by too many IBGP connections. In an AS, a router acts
as a route reflector, and other routers act as clients connecting to the route reflector. The route reflector
forwards the routing information received from a client to other clients. In this way, all clients can receive
routing information from one another without establishing BGP sessions.
Examples
# In BGP IPv4 unicast address family view, configure the local device as a route reflector and specify the
IBGP peer group test as a client.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ipv4-family unicast
[Sysname-bgp-ipv4] peer test reflect-client
# In BGP VPNv4 address family view, configure the local device as a route reflector and specify the IBGP
peer group test as a client.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] address-family vpnv4
[Sysname-bgp-vpnv4] peer test reflect-client
# In BGP-VPN IPv6 unicast address family view, configure the local device as a route reflector and specify
the IBGP peer group test as a client.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ip vpn-instance vpn1
[Sysname-bgp-vpn1] ipv6-family unicast
[Sysname-bgp-ipv6-vpn1] peer test reflect-client
