TROUBLE@ans.net

Hi. As many of you know already, Merit has turned over operations for the NSFNET service to Advanced Network and Services (ANS). ANS personnel now staff and manage the NOC and provide real-time engineering support for the backbone, while Merit retains its Internet Engineering, Network Management Systems, and Information Services groups. Merit will continue to support the NSFNET Policy Routing Database and related configuration services as well as routing coordination for the NSF regionals and midlevels. Because of this, e-mail for NOC staff is being moved to a machine in the "ans.net" domain. The TROUBLE(a)merit.edu mailbox will now be TROUBLE(a)ans.net. The merit.edu entry for TROUBLE will soon be a pointer to the ans.net list. Please begin using the ans.net address to report problems and other NSFNET NOC related issues to the ANS staff. We at Merit will remain accessible and respond quickly to your questions, problems, escalation or administrative issues related to the NSFNET backbone services. We have set up a new list called NSFNET(a)merit.edu for this purpose, and several Merit managers and senior staff will be reading this list. Feel free to use this list to communicate with us. The other existing lists to reach Merit staff will also remain operational, for example: ie(a)merit.edu The Internet Engineering group, for technical communication related to routing issues. nsfnet-admin(a)merit.edu The Policy Routing Database administration and configuration operations group, for network announcement change requests and other changes. nsfnet-info(a)merit.edu For general user-related information about the NSFNET or the Internet. Also please feel free to contact me directly if you have questions about any of this. Mark

Matt, >Oops I misspoke... > >Please do not chnage the interconnect configuration for networks normally >announced via NSS5. > >Is that better? >--MM-- The outbound configuration on the T1 NSSs at the configuration points (NSSs 17, 11, and 8) will continue as they are. The change that is planned is to the outbound announcements from the T3 to the T1. So, I think that we are in sync here, but then I thought that my original message was clear also... :-) --Elise

Matt, >Please do not change the configuration for NSS5 per your earlier plan. We >will disable our peers such that all T1 only traffic to/from PSC will >use the T1/T3 interconnects. The earlier plan did not require a change in the configuration for NSS 5, so we will be happy to maintain it as is. >Please discontinue monitoring NSS5 peers at PSC. Note that some are also >ENSS132 peers and there are NSS5 peers at other sites. Since you indicate that this will take a few days to implement, will you please send a message to trouble(a)merit.edu notifying them when the change is implemented. Thanks for letting us know your plans. I have forwarded your message to the configuration staff and the network operations center. --Elise

Hi Charley, >Well, now, I was in the same boat a few weeks ago, and asked if I should >simply ignore the T1, and was told no, it was best if I did not. > >The end result is I'm taking T1-only routes from the NSS and nothing from >the ENSS, and pointing default at the ENSS. It seems to work fine, but I'm >wondering what has changed such that a different recommendation is being >made. > >The reasons I got for continuing to take T1 routes were CLNP, relying on >the T1-T3 interconnects as a single point of failure to T1-only nets, and >being able to use the T1 as a backup for the T3 should the ENSS fail (this >is not an issue anyway as apparently I can't take a default route from the >ENSS so I can't tell when to fail default over to the T1). In the last couple of weeks, the number of networks known only to the T1 network has been reduced significantly with the change in ESnet's status. EASInet has notified of us of their plans to start peering with the T3 network within a short time frame. And we are working with CA*net to try to help them migrate to the T3. Therefore, it is not as critical to maintain peering sessions with both backbones, from the point of view of the interconnect as a single point of failure. There are just not that many T1 only networks anymore. Regionals which require the ability to pass CLNP traffic still will want to peer with the T1. However, this too should change in the near future. So if there are regionals which want to consider changes to their routing configurations with the T1 and T3 backbones, we would be happy to address your individual requirements on a case-by-case basis. For instance, Matt Mathis and I discussed this on the telephone. Since his regional is not passing CLNP traffic and the T1 backup circuit to their T3 node is due to be installed this week, he is seriously considering discontinuing his peering session with the T1. We are glad to hear that. We are very anxious to complete the migration from the T1 to the T3. Discontinuing peering sessions with the T1 is the next step. --Elise

Matt, We are in agreement with all of your points and would even encourage you to stop peering with the T1, IF the T1 safety tail is installed and you are a purely IP site (no CLNP traffic). Your suggestion to terminate peering with the T1 is completely compatible with the change we are proposing. --Elise

Just a point of clarification. The plan for dismantling the T1 calls for encapsulation of CLNP at any ENSS that runs OSI on the T1 net as an interim measure until native CLNP is available on the T3 routers. This will be done by a sepearate box which will probably be one of the RTs formerly used as the T1 router. Performance of the encapsulator is expected to be comparable or better than OSI performance on the T1 net (since there is no IP traffic to load the box), though testing is still ongoing. Native CLNP support is scheduled for first half of '93. Please keep in mind that OSI traffic at the "heavy" OSI sites is far less than IP traffic for the same sites. Providing the interim encapsualtion saves a great deal of expense by allowing the T1 network to be fully dismantled while continuing to support CLNP even though native CLNP is not ready. At no time was dropping CLNP support considered. Curtis
