Configuring EBGP between an MCE and a VPN site
To run EBGP 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 Command
Remarks
1.
Enter system view.

2.
Enter BGP instance view.

By default, BGP is not
enabled.
3.
Enter BGP-VPN instance
view.
ip vpn-instance
vpn-instance-name
Configuration commands in
BGP-VPN instance view are
the same as those in BGP
instance view. For more
information, see
Layer 3—IP
Routing Configuration Guide.
4.
Configure an EBGP peer.
peer
{
group-name
|
ipv4-address
[
mask-length
] }
as-number

By default, no BGP peers or
peer groups exist.

6.
Enable BGP to exchange
IPv4 unicast routes with
the peer.
peer
{
group-name
|
ipv4-address
[
mask-length
] }
enable
By default, BGP does not
exchange IPv4 unicast routes
with any peer.
7.
Allow the local AS
number to appear in the
AS_PATH attribute of
routes received from the
peer, and set the
maximum number of
repetitions.
peer
{
group-name
|
ipv4-address
[
mask-length
] }
allow-as-loop
[

By default, BGP discards
incoming route updates that
contain the local AS number.
