This link seems to be having issues. It has two rockets between the mikrotik devices which does make it difficult to see what's what, but it seems the tx ccq on one side is bad.
And the other:
Note the poor tx CCQ on this one.
I tried to run a BW test but was not really possible.
I've left the link up but disabled OSPF on the link by disabling the OSPF network for the link on 172.26.133.126. Link needs some work. Please bring up to CTWUG standards before enabling OSPF.
