Configuring Bgp Mdt; Configuration Prerequisites; Configuring Bgp Mdt Peers Or Peer Groups; Configuring A Bgp Mdt Route Reflector - HP A6600 Configuration Manual

With switch-group reuse logging enabled, the generated group address reuse logging information will be
sent to the information center, where you can configure the rules for outputting the logging information.
For more information about the configuration of the information center, see Network Management and
Monitoring Configuration Guide.

Configuring BGP MDT

If PIM-SSM is running in the public network, you need to configure BGP MDT.

Configuration prerequisites

Before you configure BGP MDT, complete the following tasks:
Configure MPLS L3VPN
•
Configure basic BGP functions
•
Determine the route reflector cluster ID
•

Configuring BGP MDT peers or peer groups

With BGP MDT peers or peer groups configured, a PE exchanges the BGP MDT routing information with
other PEs to obtain their addresses and thus establish a share-MDT.
To do...
1. Enter system view.
2. Enter BGP view.
3. Enter BGP MDT
sub-address family
view.
4. Enable a BGP MDT
peer or peer group.
5. Add a peer to the BGP
MDT peer group.
A BGP MDT peer or peer group is a peer or peer group created in BGP-MDT subaddress family view.

Configuring a BGP MDT route reflector

BGP MDT peers in the same AS must be fully meshed to maintain connectivity. However, when many BGP
MDT peers exist in an AS, connection establishment among them might cause great expenses. To reduce
connections between them, you can configure one of them as a route reflector and specify other routers
as clients. The clients establish BGP MDT connections with the route reflector, and the route reflector
forwards (reflects) BGP MDT routing information between clients. In this way, the clients need not to be
fully meshed. Furthermore, you can disable client-to-client reflection to reduce overloads if the clients have
been fully meshed.
The route reflector and its clients form a cluster. In general, a cluster has only one route reflector whose
router ID identifies the cluster. However, you can configure several route reflectors in a cluster to improve
network reliability, and they must have the same cluster ID configured to avoid routing loops.
Use the command...
system-view
bgp as-number
ipv4-family mdt
peer { group-name | ip-address }
enable
peer ip-address group group-name

Required.
Disabled by default.
Optional.
By default, a BGP MDT peer belongs to
no peer groups.
