1. Configurations on the MCE
To configure the MCE:
Step Command Remarks
1. 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
vpn-instance-name
N/A
4. Configure an IBGP peer.
peer { group-name | ip-address }
as-number as-number
N/A
5. Configure the system to be the
RR and specify the peer as the
client of the RR.
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.
8. 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.
2. Configurations on the VPN site
To configure the VPN site:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter BGP view. bgp as-number N/A
3. Configure the MCE as the
IBGP peer. peer { group-name | ip-address }
as-number as-number
N/A
4. Redistribute the IGP routes of
the VPN.
import-route protocol [ process-id ]
[ med med-value | route-policy
route-policy-name ] *
Optional.
A VPN site must advertise the VPN
network addresses it can reach to
the connected MCE.
Configuring routing between MCE and PE
