563BConfiguring 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.
system-view
N/A
2. Enter BGP instance view.
bgp
as-number [
instance
instance-name ]
[
multi-session-thread
]
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
as-number
By default, no BGP peers or
peer groups exist.
5. Enter BGP-VPN IPv4
unicast address family
view.
address-family ipv4
[
unicast
]
N/A
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
[ number ]
By default, BGP discards
incoming route updates that
contain the local AS number.
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.
2. Configure a VPN site:
