Binding IS-IS processes to VPN instances can isolate routes of different VPNs. For more information
about IS-IS, see
Layer 3—IP Routing Configuration Guide
.
To configure IS-IS between an MCE and a VPN site:
Step
Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Create an IS-IS process for a
VPN instance and enter
IS-IS view.
isis
[
process-id
]
vpn-instance
vpn-instance-name
Perform this configuration on the
MCE. On a VPN site, configure a
common IS-IS process.
3.
Configure a network entity
title.
network-entity net
By default, no NET is configured.
4.
Redistribute
remote site
routes advertised by the PE
into IS-IS.

By default, IS-IS does not
redistribute routes from any other
routing protocol.
If you do not specify the route
level in the command, the
command redistributes routes to
the level-2 routing table by
default.
5.
Return to system view.

6.
Enter interface view.

N/A
7.
Enable the IS-IS process on
the interface.

By default, IS-IS is disabled.
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.
You can configure filtering policies to filter received routes and advertised routes.
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 EBGP peer.
peer
{
group-name
|
ip-address
[
mask-length
]
}
as-number
as-number
By default, no BGP peer is
configured.
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.
