Chapter 35 IP Multicast Routing Configuration DGS-3610 Series Configuration Guide
To configure the sending interval of Hello message, please execute the following commands
in the interface mode:
DGS-3610(config-if)# ip pim
query-interval seconds
Set the sending interval of the Hello message on the
interface as seconds (unit: sec).
DGS-3610(config-if)# no ip pim
query-interval
Restore the sending interval of Hello message in the
interface to default value.
The sending interval of Hello message in the interface is 30 seconds by default.
When the sending interval of the Hello message is updated, the Hello hold
time will be updated as 3.5 times of the Hello sending interval
automatically.
35.6.21.3 Configuring PIM-DM State Refresh
In the administration mode, it is permitted to forward PIM-DM state refresh control message
by default. For the first-hop router directly connected to the source, the interface
configuration state refresh interval is the interval at which the state refersh packets are sent.
In this case, it is only effective for the upstream interfaces. For subsequent routers, it is the
interval at which the interfaces are allowed to receive and process the state refresh packets.
No ip pim
state-refresh isable
Allow to process and forward state-refresh messages.
ip pim state-refresh origination-interval
[interval]
configure the interval of sending state refresh message
periodically on the first hop directly connected to
source, which is valid only to upstream interfaces. For
subsequent routers, it is the interval of sending state
refresh message which is permitted to receive and
process on the interface.
The following example shows how to configure the interval of state refresh message on the
FastEthernet0/1 interface.
ip multicast-routing
!
interface FastEthernet 0/1
ip address 172.16.8.1 255.255.255.0
ip pim state-refresh origination-interval 60
ip pim dense-mode
