rlPimInterfaceStubInterface
Module: CISCOSB-PIM-MIB
OID (symbolic): CISCOSB-PIM-MIB::rlPimInterfaceStubInterface
OID (numeric): 1.3.6.1.4.1.9.6.1.101.211.1.1.5
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-create
Description: Whether this interface is a 'stub interface' with regard to PIM. If this is set to 'true', no PIM packets are sent or processed (if received) on this interface. This should be set to 'true' if there are no other PIM routers on the interface but there may be untrusted hosts on the interface, to prevent the router processing forged PIM messages from those hosts. If there are other PIM routers on this interface, this must be left as 'false'.
Changing the value of this object while the interface is operational causes the interface to be deactivated and then reactivated.
What is rlPimInterfaceStubInterface?
This read-create TruthValue, when true, marks an interface as a PIM stub so no PIM packets are sent or processed on it, appropriate when there are no other PIM routers on the interface but there may be untrusted hosts that could forge PIM messages. It's a security control an admin uses to keep PIM off segments where it isn't needed and could be abused. For example, setting this to true on a LAN segment with only end-user hosts and no other PIM routers prevents a malicious host on that segment from injecting forged PIM messages.
