By default, no routes are
redistributed into BGP.
A VPN site must advertise the
VPN network addresses it can
reach to the connected MCE.
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:
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.
ip vpn-instance
vpn-instance-name
N/A
4. Configure an IBGP peer.
peer { group-name | ip-address }
as-number as-number
N/A
5. Enter BGP-VPN IPv4 unicast
address family view.
address-family ipv4 [ unicast ] N/A
6. Enable BGP to exchange
IPv4 unicast routes with the
peer.
peer { group-name | ip-address }
enable
By default, BGP does not
exchange IPv4 unicast routes
with any peer.
7. (Optional.) Configure the
system to be the RR, and
specify the peer as the client
of the RR.
peer { group-name | ip-address }
reflect-client
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).
8. Redistribute remote site
routes advertised by the PE
into BGP.
import-route protocol
[ process-id | all-processes ]
[ allow-direct | med med-value |
route-policy route-policy-name ]
*
By default, no routes are
redistributed into BGP.
9. (Optional.) Configure
filtering of advertised routes.
filter-policy { acl-number |
prefix-list prefix-list-name }
export [ protocol process-id ]
By default, BGP does not filter
advertised routes.
10. (Optional.) Configure
filtering of received routes.
filter-policy { acl-number |
prefix-list prefix-list-name }
import
By default, BGP does not filter
received routes.
2. Configure a VPN site:
