6. Redistribute the IGP routes
of the VPN into BGP.
Configuring IBGP between MCE and VPN site
To run IBGP between an MCE and a VPN site, you must configure a BGP peer for each VPN
instance on the MCE, and redistribute the IGP routes of each VPN instance on the VPN site.
1. Configure the MCE:
Step
1. Enter system view.
2. Enter BGP view.
3. Enter BGP-VPN instance
view.
4. Configure an IBGP peer.
5. Enter BGP-VPN IPv4 unicast
address family view.
6. Enable BGP to exchange
IPv4 unicast routes with the
peer.
7. (Optional.) Configure the
system to be the RR, and
specify the peer as the client
of the RR.
8. Redistribute remote site
routes advertised by the PE
into BGP.
9. (Optional.) Configure filtering
of advertised routes.
10. (Optional.) Configure filtering
of received routes.
2. Configure a VPN site:
Command
import-route protocol
[ { process-id | all-processes }
[ allow-direct | med med-value |
route-policy route-policy-name ]
* ]
Command
system-view
bgp as-number
ip vpn-instance
vpn-instance-name
peer { group-name | ip-address
[ mask-length ] } as-number
as-number
address-family ipv4 [ unicast ]
peer { group-name | ip-address
[ mask-length ] } enable
peer { group-name | ip-address
[ mask-length ] } reflect-client
import-route protocol
[ process-id | all-processes ]
[ allow-direct | med med-value |
route-policy route-policy-name ]
*
filter-policy { acl-number |
prefix-list prefix-list-name }
export [ protocol process-id ]
filter-policy { acl-number |
prefix-list prefix-list-name }
import

Remarks
By default, no routes are
redistributed into BGP.
A VPN site must advertise
the VPN network addresses
it can reach to the connected
MCE.

By default, BGP does not
exchange IPv4 unicast
routes with any peer.
By default, no RR or RR
client is configured.
After you configure a VPN
site as an IBGP peer, the
MCE does not advertise the
BGP routes learned from the
VPN site to other IBGP
peers, including VPNv4
peers. The MCE advertises
routes learned from a VPN
site only when you configure
the VPN site as a client of
the RR (the MCE).
By default, no routes are
redistributed into BGP.
By default, BGP does not
filter advertised routes.
By default, BGP does not
filter received routes.
