Configuring A Bgp Mdt Route Reflector - HP MSR2003 Configuration Manual

The MDT information includes the IP address of the PE and the default-group to which the PE belongs. On
a public network running PIM-SSM, the multicast VPN establishes a default-MDT rooted at the PE
(multicast source) based on the MDT information.
Perform the following tasks on the PE.
To configure BGP MDT peers or peer groups:
Step
1. Enter system view.
2. Enter BGP view.
3. Create a BGP IPv4 MDT
address family and enter
its view.
4. Enable the MDT routing
information exchanging
capability between local
routers and their BGP
peers or peer groups.

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 result in increased costs. To
reduce connections between them, you can configure one of them as a route reflector and specify other
routers as clients.
When clients establish BGP MDT connections with the route reflector, the route reflector forwards (or
reflects) BGP MDT routing information between clients. The clients are not required to be fully meshed. To
save the bandwidth if the clients have been fully meshed, you can disable the routing reflection between
clients by using the undo reflect between-clients command. 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. You must configure
the same cluster ID for them to avoid routing loops.
Perform the following tasks on the PE. For more information about the commands in this procedure, see
Layer 3—IP Routing Command Reference.
To configure a BGP MDT route reflector:
Step
1. Enter system view.
2. Enter BGP view.
3. Enter BGP IPv4 MDT address
family view.
Command
system-view
bgp as-number
address-family ipv4 mdt
peer { group-name | ip-address }
enable
Command
system-view
bgp as-number

Remarks

N/A
By default, no BGP IPv4 address family
exists.
By default, local routers cannot
exchange BGP MDT routing information
with their peers or peer groups.
IMPORTANT:
Before you configure this command,
you must create BGP peers or peer
groups in BGP view. For more
information, see Layer 3
