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 for only 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
