R21xx-HP FlexFabric 11900 Layer 3 IP Routing Command Reference

306
ip-address: Specifies the cluster ID in the format of an IPv4 address in dotted decimal notation.
Usage guidelines
The route reflector and clients form a cluster. Typically a cluster has one route reflector. The ID of the route
reflector is the cluster ID.
You can configure more than one route reflector in a cluster to improve network reliability and prevent a
single point of failure. Use this command to configure the same cluster ID for all route reflectors in the
cluster to avoid routing loops.
Do not configure the router ID of a client as the cluster ID.
Examples
# In BGP IPv4 unicast address family view, configure the cluster ID on the local router (a reflector in the
cluster) as 80.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ipv4-family unicast
[Sysname-bgp-ipv4] reflector cluster-id 80
# In BGP VPNv4 address family view, configure the cluster ID on the local router (a reflector in the cluster)
as 80.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] address-family vpnv4
[Sysname-bgp-vpnv4] reflector cluster-id 80
# In BGP-VPN IPv4 unicast address family view, configure the cluster ID on the local router (a reflector in
the cluster) as 80.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ip vpn-instance vpn1
[Sysname-bgp-vpn1] ipv4-family unicast
[Sysname-bgp-ipv4-vpn1] reflector cluster-id 80
# In BGP IPv6 unicast address family view, configure the cluster ID on the local router (a reflector in the
cluster) as 80.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ipv6-family unicast
[Sysname-bgp-ipv6] reflector cluster-id 80
