Configuring The Hello Interval; Configuring Pim Neighbors - 3Com 5500-EI PWR Install Manual

If you have configured a basic ACL, the switch filters all the received multicast packets based on
the multicast source address, and discards packets that fail source address match.
If you have configured an advanced ACL, the switch filters all the received multicast packets based
on the multicast source address and group address, and discards packets that fail source and
group address match.

Configuring the Hello Interval

In a PIM domain, a PIM router discovers PIM neighbors and maintains PIM neighboring relationships
with other routers by periodically sending hello messages.
Follow these steps to configure the Hello interval:
To do...
Enter system view
Enter interface view
Configure the Hello interval on
the interface
Before configuring related PIM functions, you must enable PIM-DM or PIM-SM first.

Configuring PIM Neighbors

In order to prevent plenty of PIM neighbors from exhausting 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 through
commands.
You can define what Layer 3 switches can become PIM neighbors of the current interface by configuring
a basic ACL.
Follow these steps to configure PIM neighbors:
To do...
Enter system view
Enter interface view
Use the command...
system-view
interface interface-type
interface-number
pim timer hello seconds
Use the command...
system-view
interface interface-type
interface-number
16
