CURRENT_MEETING_REPORT_ Reported by John Moy/Proteon OSPF Minutes The OSPF Working Group met Thursday, March 14th at the St. Louis IETF. The main topic of dicussion was the OSPF MIB. Fred Baker and Rob Coltun had published the OSPF MIB as an Internet Draft, and had received a number of comments, especially from the Network Management Directorate. Their chief comment was that there were too many variables. So the Working Group went through the MIB variable by variable, to see which variables could be combined and which could be discarded. We ended up reducing the 127 original variables to 101. A number of other things were also discussed: o Fred Baker pointed out that, for all MIB groups that can be dynamically created/destroyed, there needs to be an extra variable to accomplish deletion. This will add to the size of the MIB. o Some time was spent in discussing how to do route filtering in OSPF at area boundaries. This can be done through selective non-advertisement of certain area ranges. John Moy pointed out that this is dangerous to do in transit areas. It was decided that since this type of route filtering is not covered in the OSPF spec, it would not be mentioned in the OSPF MIB either. o Dino Farinacci mentioned a problem he encountered where an OSPF router (call it router X) received an external LSA originated by router Y which listed one of X's IP addresses as the forwarding address. After performing its routing table calculation, router X ended up pointing at itself for the destination. It was agreed the the spec should say that, when performing the routing table calculation, those external LSAs whose forwarding address is one of the router's own addresses should be ignored. [Editor's note: The very existence of such an advertisement probably indicates a problem in the exchange of information between OSPF and other protocols such as RIP/EGP]. o We agreed that all configuration items in the MIB will have read/write access, but that the MIB will say that in the absence of adequate authentication the variables can be implemented as read-only. There was not enough time at the meeting for examination of the OSPF Trap MIB that Rob Coltun has created. We plan on discussing this 1 document via electronic mail.
