Redistribute the IGP routes
of the VPN into BGP.

protocol
[ {
process-id
|

}
[

]
* ]
By default, no routes are
redistributed into BGP.
A VPN site must advertise
the VPN network addresses
it can reach to the connected
MCE.
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
Command Remarks
1.
Enter system view.
system-view
N/A
2.
Enter BGP view.
bgp
as-number
N/A
3.
Enter BGP-VPN instance
view.
ip vpn-instance
vpn-instance-name
N/A
4.
Configure an IBGP peer.
peer
{
group-name
|
ip-address
[
mask-length
] }
as-number
as-number
N/A
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
|
ip-address
[
mask-length
] }
enable
By default, BGP does not
exchange IPv4 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
|
ip-address
[
mask-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 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).
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.
9.
(Optional.) Configure filtering
of advertised routes.
filter-policy
{
acl-number
|
prefix-list
prefix-list-name
}
export
[
protocol process-id
]
By default, BGP does not
filter advertised routes.
10.
(Optional.) Configure filtering
of received routes.
filter-policy
{
acl-number
|
prefix-list
prefix-list-name
}
import
By default, BGP does not
filter received routes.
