DES-7200 Configuration Guide Chapter 5 PIM-DM
Configuration
5-4
By default, the interval of sending the Hello message on the interface is 30s.
Note
When the interval of sending the Hello message is updated, the Hello hold time
will be updated as 3.5 times of the Hello sending interval automatically. If the
interval of sending Hello message multiplying 3.5 is larger than 65535, the Hello
message hold time should be updated to 65535.
5.2.4 Configuring the propagation-delay of Hello Message
To configure the propogation delay of Hello message, run the following command
in the interface configuration mode:
Command Function
DES-7200(config-if)# ip pim
propagation-delay
interval-milliseconds
Set the propagation delay in the range
of 1 to 32767 milliseconds.
DES-7200(config-if)# no ip pim
propagation-delay
Restore the setting to the default value,
500 milliseconds by default.
5.2.5 Configuring the override-interval of Hello Message
To configure the override-interval, run the following command in the interface
configuration mode:
Command Function
DES-7200(config-if)# ip pim
override-interval
interval-milliseconds
Set the override interval in the range of
1 to 65535 milliseconds.
DES-7200(config-if)# no ip pim
override-interval
Restore the setting to the default value,
2500 milliseconds by default.
5.2.6 Configuring PIM-DM Neighbor Filtering
Neighbor filtering function can be configured on the interface to enhance network
security. With neighbor filtering enabled, the PIM-DM will not establish the
neighborhood relationship with the neighbor or stop the currently established
neighborhood relationship with the neighbor as long as a neighbor is denied by
the access list.
To configure the PIM neighbor filtering function, run the following command in the
interface configuration mode:
Command Function
DES-7200(config-if）#ip pim
neighbor-filter access-list
Enable the PIM neighbor filtering function
on the current interface.
DES-7200(config-if）#no ip pim
neighbor-filter access-list
Disable the PIM neighbor filtering function
on the current interface.
The PIM neighbor filtering function is disabled by default on an interface.
Note
ip pim neighbor-filter command description:
When the associated ACL rule is set to permit, only the neighbor addresses in
the ACL list can be considered to be the PIM neighbor of the current interface.
When the associated ACL rule is set to deny, the neighbor addresses in the
ACL list cannot be considered to be the PIM neighbor of the current interface.
