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
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.)
system to be the RR, and
specify the peer as the client
of the RR.
8. Redistribute
routes advertised by the PE
into BGP.
9. (Optional.)
filtering of advertised routes.
(Optional.)
10.
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
BGP-VPN instance
ip vpn-instance
vpn-instance-name
peer { group-name | ip-address }
as-number as-number
address-family ipv4 [ unicast ]
peer { group-name | ip-address }
enable
Configure the
peer { group-name | ip-address }
reflect-client

export [ protocol process-id ]
filter-policy { acl-number |
Configure
prefix-list prefix-list-name }

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.
