PIM/4/HW_UPSTREAM_NOPIM

PIM/4/HW_UPSTREAM_NOPIM

Message

PIM/4/HW_UPSTREAM_NOPIM:In the VPN instance, PIM is not enabled on the upstream interface. (VPNName=[VPNName], IfName=[IfName], DestAddr=[DestAddr])

Description

PIM selects the interface as the inbound interface of the PIM entry according to a unicast route. The interface, however, does not support PIM. So the device cannot generate complete PIM entries and cannot send PIM Join messages to the upstream interface. As a result, traffic diversion fails.

Parameters

Parameter Name Parameter Meaning

VPNName

VPN instance name

IfName

Interface name

DestAddr

Destination address

Possible Causes

PIM selects the interface as the inbound interface of the PIM entry according to a unicast route. The interface, however, does not support PIM.

Procedure

  1. Obtain the interface information according to this log and determine whether the interface supports pim sm.

    • If the interface supports pim sm and multicast traffic passing through this interface complies with the planning, run the pim sm command on the interface to enable PIM. Then, check whether multicast entries are normal.
      • If so, go to Step 4.
      • If not, go to Step 3.
    • If the interface does not support pim sm, go to Step 2.

  2. Configure a static unicast route to the multicast source or RP and ensure that the outbound interface specified in this route supports pim sm. Then, run the pim sm command on the outbound interface.
  3. Collect alarm information and configuration information, and then contact technical support personnel.
  4. End.
