Ste
Command
Remarks
6. Enable route reflection
between clients.
reflect between-clients
Optional.
Enabled by default.
If the clients are fully meshed, you
do not need to enable route
reflection.
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.
NOTE:
• 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 chan
e the next hop of a route, confi
ure
an inbound policy on the receiving side of the route.
2. Configure the CE:
Ste
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.
