Command Remarks
7. Configure the cluster
ID for the RR.
reflector cluster-id { cluster-id |
ip-address }
Optional.
By default, each RR in a cluster uses its
own router ID as the cluster ID.
If more than one RR exists in a cluster,
use this command to configure the
same cluster ID for all RRs in the cluster
to avoid routing loops.
8. Configure BGP to
filter routes to be
advertised.
filter-policy { acl-number | ip-prefix
ip-prefix-name } export [ direct | isis
process-id | ospf process-id | rip
process-id | static ]
Optional.
By default, BGP does not filter routes to
be advertised.
9. Configure BGP to
filter received routes.
filter-policy { acl-number | ip-prefix
ip-prefix-name } import
Optional.
By default, BGP does not filter received
routes.
You can execute the reflect between-clients command and the reflector cluster-id command in multiple
views, such as BGP-VPN instance view and BGP-VPNv4 subaddress family view. The two commands take
effect only on the RR in the view where they are executed. For RRs in other views, they do not take effect.
Configuring an RR does not change the next hop of a route. To change the next hop of a route, configure
an inbound policy on the receiving side of the route.
2. Configure the CE:
Ste
p
Command Remarks
1. Enter system view.
system-view N/A
2. Enter BGP view.
bgp as-number N/A
3. Configure the PE as the IBGP
peer.
peer { group-name | ip-address }
as-number as-number
For information about BGP peer
and BGP peer group
configuration, see Layer 3—IP
Routing Configuration Guide. This
chapter does not differentiate
between peer and peer group.
4. Configure the route
redistribution and
advertisement behavior.
import-route protocol [ process-id ]
[ med med-value | route-policy
route-policy-name ] *
Optional.
A CE must advertise its routes to the
connected PE so the PE can
advertise them to the peer CE.
NOTE:
• Exchange of BGP routes of a VPN instance is the same as that of ordinary BGP routes.
• The BGP configuration task in BGP VPN instance view is the same as that in BGP view. For more
information, see
Layer 3—IP Routing Configuration Guide .
