neighbor-check (IPv6)

Function

The neighbor-check command enables the PIM neighbor check function.

The undo neighbor-check command restores the default setting.

By default, the PIM neighbor check function is not enabled.

Format

neighbor-check { receive | send }

undo neighbor-check { receive | send }

Parameters

Parameter	Description	Value
receive	Checks whether the Join/Prune and Assert messages are received from a PIM neighbor. If not, these messages are discarded.	-
send	Checks whether the Join/Prune and Assert messages are sent to a PIM neighbor. If not, these messages are not sent.	-

Views

PIM-IPv6 view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

PIM devices send Join/Prune messages to the upstream PIM neighbor to perform join and prune actions and PIM neighbors often exchange Assert messages. To save system resources and protect security of Join/Prune messages and Assert messages, run the neighbor-check command to enable the PIM neighbor check function.

Prerequisites

IPv6 multicast routing has been enabled using the multicast ipv6 routing-enable command in the system view.

Precautions

You can specify both receive and send to enable the PIM neighbor check function for the received and sent Join/Prune and Assert messages.

This command is valid for only PIM-SM (IPv6).

Example

# In the PIM-IPv6 view, enable the PIM neighbor check function for the received Join/Prune and Assert messages.
