Enter system view.
system-view
N/A
2.
Enter BGP view.
bgp as-number N/A
3.
Enter BGP-VPN instance view. ipv4-family vpn-instance

peer { group-name | ip-address }
reflect-client
Optional.
By default, no RR or RR client is
configured.
6.
Redistribute remote site routes
advertised by the PE.
import-route protocol [ process-id
| all-processes ] [ med med-value |
route-policy route-policy-name ] *
By default, no routes of any other
protocol are redistributed to BGP.
7.
Configure a filtering policy to
filter the 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 the
routes to be advertised.

Configure a filtering policy to
filter received routes.
filter-policy { acl-number |
ip-prefix ip-prefix-name } import
Optional.
By default, BGP does not filter the
received routes.
NOTE:
When a CE is configured as an IBGP peer, the MCE does not advertise the BGP routes learned from this
CE to other IBGP peers, including VPNv4 peers. Only when you configure a CE as a client of the RR (the
MCE), does the MCE advertise routes learned from it to other IBGP peers.
