Step
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 instance view.
3. Enter BGP-VPN instance
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.) Configure the
system to be the RR, and
specify the peer as the
client of the RR.
8. Redistribute remote site
routes advertised by the
PE into BGP.
2. Configure a VPN site:
Step
1. Enter system view.
2. Enter BGP instance view.

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.
Remarks
N/A
By default, BGP is not enabled.
N/A
By default, no BGP peers or
peer groups exist.
N/A
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.
Remarks
N/A
By default, BGP is not enabled.
