Configuring IBGP between MCE and VPN site
If IBGP is used for exchanging routing information between an MCE and VPN sites, you must configure
a BGP peer for each VPN instance, and redistribute the IGP routes of each VPN instance on the VPN
sites.
1. Configure the MCE:
Ste
p
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.
After you configure a VPN site as
an IBGP peer of the MCE, the MCE
does not advertise the BGP routes
learned from the VPN site to other
IBGP peers, including VPNv4
peers. Only when you configure
the VPN site as a client of the RR
(the MCE), does the MCE advertise
routes learned from it to other IBGP
peers.
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 route redistribution
is configured.
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 the received routes.
filter-policy { acl-number |
ip-prefix ip-prefix-name } import
Optional.
By default, BGP does not filter the
received routes.
2. Configure the VPN site:
Ste
p
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
