Configuring Mbgp Community; Configuring An Mbgp Route Reflector - HP A6600 Configuration Manual

Configuring MBGP community

The community attribute can be advertised between MBGP peers in different ASs. Routers in the same
community share the same policy.
You can reference a routing policy to modify the community attribute for routes sent to a peer. In addition,
you can define extended community attributes as needed.
To do...
1. Enter system view.
2. Enter BGP view.
3. Enter IPv4 MBGP address family view.
4. Advertise the
community
attribute to an
MBGP
peer/peer
group.
5. Apply a routing policy to routes
advertised to an MBGP peer/peer
group.
When configuring MBGP community, you must reference a routing policy to define the specific
community attributes, and apply the routing policy for route advertisement.
For routing policy configuration, see Layer 3—IP Routing Configuration Guide.

Configuring an MBGP route reflector

To guarantee the connectivity between multicast iBGP peers in an AS, you need to make them fully
meshed. But this becomes unpractical when large numbers of multicast iBGP peers exist. Configuring
route reflectors can solve this problem.
To do...
1. Enter system view.
2. Enter BGP view.
3. Enter IPv4 MBGP address
family view.
4. Configure the router as a
route reflector and specify an
MBGP peer/peer group as its
client.
5. Enable route reflection
between clients.
Use the command...
system-view
bgp as-number
ipv4-family multicast
a. Advertise the
community
attribute to
peer { group-name | ip-address }
an MBGP
advertise-community
peer/peer
group.
b. Advertise the
extended
community
peer { group-name | ip-address }
attribute to
advertise-ext-community
an MBGP
peer/peer
group.
peer { group-name | ip-address }
route-policy route-policy-name
export
Use the command...
system-view
bgp as-number
ipv4-family multicast
peer { group-name |
peer-address } reflect-client
reflect between-clients
