interface any more, and vice versa.
z When PIM-DM is enabled on an interface of the switch, only PIM-DM can be
enabled on the other interfaces of the switch, and vice versa.
7.2.3 Configuring PIM Neighbors
In order to prevent plenty of PIM neighbors from using out the memory of the router,
which may result in router failure, you can limit the number of PIM neighbors on the
router interface. However, the total number of PIM neighbors of a router is defined by
the system, and you cannot modify it by using commands.
You can configure basic ACL 2000 to 2999 (refer to the part about ACL in this manual).
Only the filtered Layer 3 switches (routers) cam serve as the PIM neighbors of the
current interface.
