I have a couple of questions about routing, arp and IRE tables in the kernel. I looked for an ip-interest alias but didn't find anything so apologies in advance. I know this is opensolaris based and I am specifically looking at Solaris 9 but it was suggested I try here....
Customer sees an event where bi-directional communication is lost. In the problem scenario, "they" can talk to us but we can't talk to them. We can see that "they" are trying to open connections and we can talk to anyone else and so can "they". We've gone through the typical tools (arp -a, netstat -rn, etc) and nothing pops out. My customer does not get notified until the problem has corrected itself. They believe it to be an arp issue because of the above. It also self corrects in about 40 minutes - notably twice the default of the ip_ire_arp_interval (1200000 or 20 minutes). I'm interested specifically in what the ipv4_ire_status, ipv4_mrtun_ire_status, and ipv4_srcif_ire_status outputs mean. From what I can see, the first one looks a lot like a routing table and the second two are empty. Customer is convinced that this has some bearing on their case probably because of the overwhelming lack of documentation. Can someone tell me what any of the output (stored in the ipv4_ire_status variable) is and what is it used for? Is it used by any other tool such as netstat and arp - source code doesn't seem to show that but I could have missed it. Hope this isn't too vague and thanks in advance, -dan -- This message posted from opensolaris.org _______________________________________________ networking-discuss mailing list [email protected]
