Multi-home with same provider, BGP convergence issues

Hello, I have sort of an interesting problem, that probably has an easy fix. I've ran into a continuous BGP convergence problem on the cores of the network I administer every time I bring up both of our Savvis connections (we have a single OC-12 and 2 1GigE connections in a multi-hop configura

Re: Network SLA

Anyone interested in setting up his own IP SLA probes by hand and then collect the measurements into a database, can use a Perl tool we developed at 2005: http://sourceforge.net/projects/saa-collector It's rather old (SAA got renamed into IPSLA in the meantime) and, in retrospect, the code is a l

Re: Multi-home with same provider, BGP convergence issues

Hi Nicholas,a simple schematic would help together with configs of how you are announcing your IP blocks. But with what you have indicated, you may need to manipulate your announcements (for example using prepend) and make sure that you don't have the same IP blocks being advertised from the two

Re: Dynamic IP log retention = 0?

Just wondering but the knowledge I have of DHCP is that an IP address is assigned to the same computer (or host) and will continue to do so until the pool of IP's is exhausted. Once that occurs, a new request is parsed by the DHCP server and the oldest non-renewed lease address is checked to see

Joe, I'll respond to you and this will be my last reply to this thread because I know I won't be able to change your mind. Saying a company's business decisions are antisocial just because they aren't doing you want is very unhelpful. I don't know how many large ISPs you have worked for but I'm no

Vladis, I'm not going to argue with you on a socio economic opinion that companies who have stock holders are evil because they don't spend their funds where they want you to and promote anti-social behavior by doing so. If you think society's biggest problem is to stop port scanning then I hope y
