Configuring IBGP between an MCE and a VPN site
To use IBGP between an MCE and a VPN site, you must configure a BGP peer for each IPv6 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 view.
ip vpn-instance
vpn-instance-name
N/A
4. Configure an IBGP peer.
peer { group-name |
ipv6-address } as-number
as-number
N/A
5. Enter BGP-VPN IPv6 unicast
address family view.
address-family ipv6 [ unicast ] N/A
6. Enable BGP to exchange IPv6
unicast routes with the peer.
peer { group-name |
ipv6-address } enable
By default, BGP does not
exchange IPv6 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 |
ipv6-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 VPNv6 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 [ 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 { acl6-number |
prefix-list ipv6-prefix-name }
export [ protocol process-id ]
By default, BGP does not filter
advertised routes.
10. (Optional.) Configure filtering of
received routes.
filter-policy { acl6-number |
prefix-list ipv6-prefix-name }
import
By default, BGP does not filter
received routes.
2. Configure a 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 an IBGP
peer.
peer { group-name | ipv6-address }
as-number as-number
N/A
