Command Remarks
3. Configure the MCE as an
EBGP peer.
peer { group-name | ip-address }
as-number as-number
By default, no BGP peer or peer
group is configured.
4. Create and enter BGP-VPN
IPv4 address family view.
ipv4-family [ unicast ] N/A
5. Enable BGP to exchange IPv4
unicast routing information
with the specified peer or
peer group.
peer { group-name | ip-address }
enable
By default, BGP does not exchange
IPv4 unicast routing information
with any peer or peer group.
6. Redistribute the IGP routes of
the VPN.
import-route protocol [ process-id ]
[ med med-value | route-policy
route-policy-name ] *
By default, BGP does not
redistribute any IGP routes.
A VPN site must advertise the VPN
network addresses it can reach to
the connected MCE.
Configuring IBGP between an MCE and a VPN site
To run IBGP between an MCE and VPN sites, 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 sites.
1. Configure the MCE:

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. Specify an EBGP peer or peer
group.
peer { group-name | ip-address }
as-number as-number
By default, no BGP peer or peer
group is specified.
5. Create and enter BGP-VPN
IPv4 address family view.
ipv4-family [ unicast ] N/A
6. Enable exchange of IPv4
unicast routes with the
specified peer or peer group.
peer { group-name | ip-address }
enable
BGP cannot exchange IPv4 unicast
routes with any peer or peer
group.
7. (Optional.) Configure the
MCE as a route reflector and
configure the peer or peer
group (VPN site) as a client.
peer { group-name | ip-address }
reflect-client
By default, no RR or RR client is
configured.
To enable the MCE to forward
routes received from the VPN site to
other IBGP peers (including VPNv4
peers), you must configure the MCE
as a route reflector and configure
the VPN site as a client.
8. 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, BGP does not
redistribute routes from any other
routing protocol.
9. (Optional.) Configure a
filtering policy to filter
advertised routes.
filter-policy { acl-number |
prefix-list prefix-list-name } export
[ protocol process-id ]
By default, BGP does not filter
advertised routes.
