Configuring IBGP between an MCE and a VPN site

About 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.
Restrictions and guidelines
A VPN site must advertise VPN network addresses to the connected MCE.
Configuring the MCE
1. Enter system view.
system-view
2. Enter BGP instance view.
bgp as-number [ instance instance-name ]
By default, BGP is not enabled.
3. Enter BGP-VPN instance view.
ip vpn-instance vpn-instance-name
4. Configure the VPN site as an IBGP peer.
peer { group-name | ipv6-address [ prefix-length ] } as-number
as-number
5. Enter BGP-VPN IPv6 unicast address family view.
address-family ipv6 [ unicast ]
6. Enable BGP to exchange IPv6 unicast routes with the peer.
peer { group-name | ipv6-address [ prefix-length ] } enable
By default, BGP does not exchange IPv6 unicast routes with any peer.
7. (Optional.) Configure the local device as the RR, and specify the peer as the client of the RR.
peer { group-name | ipv6-address [ prefix-length ] } 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 | all-processes } [ allow-direct |
med med-value | route-policy route-policy-name ] * ]
By default, no routes are redistributed into BGP.
Configuring the VPN site
1. Enter system view.
system-view
2. Enter BGP instance view.
bgp as-number [ instance instance-name ]
By default, BGP is not enabled.
3. Configure the MCE as an IBGP peer.
