PIM-DM Overview 337
Only the routers that match the filtering rule in the ACL can serve as a PIM neighbor
of the current interface.
Configuring the Maximum Number of PIM Neighbor on an Interface
The maximum number of PIM neighbors of a router interface can be configured to
avoid exhausting the memory of the router or router faults. The maximum number of
PIM neighbors of a router is defined by the system, and is not open for modification.
Perform the following configuration in the PIM view.
By default, the PIM neighbors on the interface are limited to 128.
If the number of PIM neighbors of an interface has exceeded the configured value by
the time of configuration, the existing PIM neighbors will not be deleted.
Clearing Multicast Route Entries from PIM Routing Table
Perform the following configuration in User View.
If in this command, the
group-address
is 224.0.0.0/24 and
source-address
is the
RP address (where group address can have a mask, but the resulted IP address must
be 224.0.0.0, and source address has no mask), then it means only the (*, *, RP) item
will be cleared.
If in this command, the
group-address
is any a group address, and
source-address
is 0 (where group address can have a mask, and source address has no mask), then
only the (*, G) item will be cleared.
Note that this command clears not only multicast route entries from PIM routing
table, but also the corresponding route entries and forward entries in the multicast
core routing table and MFC.
Clearing PIM Neighbors
Perform the following configuration in User View.
