to improve network reliability. To avoid routing loops, make sure the route reflectors in a cluster have
the same cluster ID.
Perform this task on PE devices.
To configure a BGP MDT route reflector:
Step
Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Enter BGP instance view.
bgp
as-number
[
instance
instance-name
]
N/A
3.
Enter BGP IPv4
MDT
address family view.
address-family ipv4 mdt
N/A
4.
Configure the device as a
route reflector and specify its
peers or peer groups as
clients.
peer
{
group-name
|
ip-address
[
mask-length
] }
reflect-client
By default, neither route reflectors
nor clients exist.
5.
(Optional.)
Disable route
reflection between clients.
undo reflect between-clients
By default, route reflection between
clients is disabled.

command, see
Layer 3—IP
Routing Command Reference
.
6.
(Optional.) Configure the
cluster ID of the route
reflector.
reflector cluster-id
{
cluster-id
|
ip-address
}
By default, a route reflector uses its
router ID as the cluster ID.
