By default, a peer (group) does not perform route filtering based on the prefix list.

9.2.8 Configuring MBGP Route Aggregation

MBGP supports the manual aggregation of routes. Manual aggregation aggregates the
local MBGP routes. A series of parameters can be configured during manual route
aggregation.
Please perform the following configurations in IPV4 multicast sub-address family view.

9.2.9 Configuring an MBGP Route Reflector

To ensure the interconnectivity among MBGP peers, it is necessary to establish
fully-closed network among IBGP multicast peers. However, some internal MBGP
multicast networks are very large, and it costs a good sum to establish a fully-closed
network.
Route reflector solves this problem. The core is to specify a router as the focus of the
internal sessions. Multiple MBGP multicast routers can be peers of one central point,
namely a multiple route reflector, which in turn creates peer relationship with other
reflectors. The route reflector is the focus of other routers. The routers other than those
reflectors are called clients. The clients are in peer with route reflects and exchange
