A read-only counter tracking RIP packets received on this virtual interface that had a malformed header, such as an unsupported RIP version or fields that should be zero but weren't. A rising count here points to a misconfigured or incompatible RIP neighbor sending malformed packets, useful for an admin diagnosing why routes aren't being learned correctly from a particular peer. A steadily climbing mitelIpVGrpTableRipRxBadPkts count would prompt an admin to check whether a neighboring router is running an incompatible or misconfigured RIP version.
