Doe's anyone have an idea as to what Link State Algorithm the Cascade/Ascend 9000's switches run? I have been given conflicting reports that it is OSPF, or others say that it is OSPF "like" since John Moy worked for Cascade, he developed a version of OSPF for the Cascade/Ascend switches. Doe's anyone have more info on this? Also, if so, what version is supported on the Amethyst, Jade v.1, v.2. releases. Apparently, this may have something to do with all the instability issues with WCOM. CJ Michael Dillon wrote:

We have one PVC using NNI via MCI/Worldcom (got it from LDDS years ago). It has been bouncing up and down for the past four days.Actually, what I meant was whether this so-called packet storm has extended to frame relay networks with NNI to Worldcom. The PVC will bounce if Worldcom cannot maintain the PVC portion within their network or cannot pass traffic through their network. But the public description so far seems to imply that the problem propogates from one switch to another. Assuming this is actually what is happening, I wondered whether the problem was propogating into any other networks via NNI connections. And if the answer is yes, then what vendor made the switches, etc. etc...? -- Michael Dillon - E-mail: michael () memra com Check the website for my Internet World articles - http://www.memra.com
