HAPTER ULTICAST OMMON ONFIGURATION OMMANDS
Description
Using the multicast packet-boundary command, you can configure a multicast
forwarding boundary. Using the undo multicast packet-boundary command, you
can remove the multicast forwarding boundary configured.
By default, no multicast forwarding boundary is configured.
You can set boundary conditions for multicast packets on an interface via basic or
advanced Access Control List (ACL). Packets denied by the ACL will be discarded.
The source address of a multicast packet can be filtered through the basic ACL.
Both the source address and the destination address (source group address) of a
multicast packet can be filtered through the advanced ACL.
Example
Set boundary conditions for multicast packets through the basic ACL 1.

Parameter
limit: Limit of multicast routing table capacity, ranging from 0 to
MAX_MROUTE_LIMIT. In which, MAX_MROUTE_LIMIT differs with the different
router types.
Description
Using the multicast route-limit command, you can limit the multicast routing table
capacity. If the capacity exceeds the limit, the router will discard protocols and data
packets of the newly-added (S, G).
By default, the limit of multicast routing table capacity is MAX_MROUTE_LIMIT.
If the number of route entries in the routing table has exceeded the configured
number when configuring the command, the previous route entry in the routing
table will not be deleted. The system will prompt "The number of current route
entries is more than that configured."
If this command is executed repeatedly, the new configuration will overwrite the
previous one.
Example
Limit the multicast routing table capacity to 1000.
