I have MRP in production without this issue, too. I have never seen anything like it. I can't understand how I can receive more RHP packets than I send. CPU goes up on the line cards, the state of the secondary interface flaps between blocking and forwarding, it just gets into a bad state. As long as I don't have all the members configured and leave at least one not configured with MRP, it works as expected. The one thing I haven't done is to try to make a different unit the master.<br>

This is pretty simple. I have one vlan in an MRP ring through 4 MLX
units. I configure the master, and it works as expected. I then
configure the members. The problem is when the last "member"
(non-master) is configured in the ring, the master begins to receive thousands
of RHP and TC RBPDUs per second. It doesn't matter which one is the last
member configured but as soon as I enable RHP on that last member, the count of
RHP and TC RBPDUs goes haywire. Here is what my master currently shows:<br>
<br>
RHPs sent
RHPs rcvd TC
RBPDUs rcvd<br>
509883
4193162
3684318<br>
<br>
As you can see, it has sent about a half a million RHPs but received over 4
million of them!<br>
<br>
Only one unit is configured as "master". As long as I have MRP
unconfigured on one of the members, the ring works as expected. There is no
spanning tree of any sort running on that vlan. I am just in awe of how
RHP packets can seemingly be created in the network somewhere at such an
amazing rate!<br>
<br>
Anyone else seen anything like this? It is just plain wacky!<br>
