Hi. Does anyone here on this list filter BGP routes learnt with prefixes longer than /24 ? Thanks, Adrian -- Adrian Chadd | "Once in a lifetime, you find someone, <adrian(a)creative.net.au> | Who touches not only your heart, | But also your soul."

What happened to the access-list blahblah established command in 11.1.15? is it missing? I find some stuff about reflexive lists in 11.3 which would be nice but it disappear from 10.x to 11.1, the machine even claims I should be able to use an established parameter but doesn't offer it to me. sigh. jlw -- Jason Weisberger Chief Technology Officer SoftAware, Inc. - 310/305-0275 "Let us cross over the river, and rest under the shade of the trees." -Thomas Jonathan "Stonewall" Jackson

According to the limited information I received, the NM-1HSSI is capable of handling 45Mbps. The information I received did not disclose details of interoperability with the 2600-series.

an apology re: Quoting and threading ..
by Joe Rhett 22 Apr '98

22 Apr '98

I was overly concise in my response, and a number of people have written to correct me on this. So I'm writing to apologize, and clarify what I meant here. Someone: >>> That's a feature, not a bug. It allows people to read things in >>> context. Not a problem from my perspective as long as the quoted >>> material is at the bottom of the message. Me: >> NO, see, my e-mail package has this "feature". It lets me read mail in >> threads. I don't need people to help it out. Owen (and others with similar messages): > Well, Joe, you're not everyone, and the quotations by many of the > people are of great help to some of us, me included. I have no problem with relevant and concise quotes that help us understand the issue being addressed. My response was aimed at someone who felt that the entire thread should be preserved in each and every message -- this is completely unnecessary! If someone wants to read the entire thread, they should use a threaded mail reader. The messages themselves should contain only enough quoted information to assist in understanding the response. -- Joe Rhett Systems Engineer JRhett(a)ISite.Net ISite Services PGP keys and contact information: http://www.navigist.com/Staff/JRhett

AT&T Outage cause last week.
by Rodney Joffe 22 Apr '98

22 Apr '98

According to AT&T, in a story just released, the problem was a Cisco code problem. It would be interesting to hear what the actual software cause was, if anyone from Cisco cares to let us know?.../rlj - - - AT&T's network failure AT&T Corp. reported today that last week's frame relay network failure was due to a software-based problem. Last Monday's network failure disrupted service nationally for thousands of AT&T's business customers for about a day. The cause of the outage was previously attributed to the interaction between two frame-relay switches, but AT&T now says it was a software problem. AT&T Chairman C. Michael Armstrong said today the company is working closely with Cisco Systems, which provided its switches, on ways to fix the problem. The type of network application affected by frame-relay service is "any kind of high-speed data applications where large amounts of information [are] exchanged in quick bursts," Granieri said. Querying an inventory database is one example of such an application, he said. Reuters contributed to this report
