log BGP state changes
by Jon Mansey 07 Jan '99

07 Jan '99

Hi, I hope this is on topic (-: "How can I make my router....." I would like my routers to log to syslogd everytime a BGP session changes state. Is there a way to set logging to report this?

TierraNet (ASN 10732) is advertising 209.240.128.0/19, which includes 209.240.157.34 (ns1.netcolony.com) ARIN reports that they've only been allocated 209.240.128.0/20 and that the other half of the /19 that they're announcing (209.240.144.0/20) is unallocated. Perhaps ARIN has reserved the entire /19 for TierraNet, but only actually allocated the lower /20 to them? Perhaps TierraNet is announcing their /20 as a /19 to get past Sprint's route filters? -Richard

The ISI version 3.x tools are RIPE181 compliant and version 4.x are RPSL tools exclusively. Please let me know if you have any problems. regards, --jerry ps Unfortunately, ISI does not default to our server and you must specifically set a command line flag so the tools can parse the server output. Check the man page for the correct flag to select.

Well...that explains why they're announcing a /19 when they've been allocated a /20, but it leaves the question "Why do they have machines with addresses in the top portion of the /19 announcement that are not in the /20 they've been allocated?" -Richard

From: Henk Smit <hsmit(a)cisco.com> > Most of the large ISPs in the US run IS-IS as their IP IGP. > In europe a number of PTTs have chosen IS-IS as the IGP for their new > IP Internet backbones. That might be an indication if IS-IS is dead. This points out the real issue. OSPF and IS-IS are close enough that other factors usually outweigh their differences. The choice of IS-IS in this case is really the result of the choice of an equipment vendor. These days at least, vendors are not chosen because they implement IS-IS. IS-IS is chosen because of some vendors' protocol implementations.

We should also point out that the IETF is now an OSI liason organization and can make contributions to the ISO process. Further, given the technical expertise of the folks working in the IETF, the effective death of CLNP, and the fact that a significant proportion of the systems running IS-IS are actually doing so to forward IP, any contributions made by the IETF will be taken very seriously by ISO.
