Hello, I am using ASA8.0 software. I also tried to use 'downloadable ACL' attribute, this attribute does the job as its name says. But cisco-av-pair cannot. Is there another possible reason? Thanks. ... View more

I am not clear about the relationship between RA-interval and RA-lifetime. Is it true that RA will be sent every RA-interval to Client within RA-lifetime? So, when the RA-lifetime is expired, the RA-interval will not be functional any more. If this is ture, the problem is nothing to do with RA-interval. Instead, it is all about RA-lifetime. Am I right? By the way, I use cisco router to simulate the client. The configuration is done following the document http://docwiki.cisco.com/wiki/IPv6_ISATAP_configuration_example_with_a_Cisco_router_as_a_client Thank you for your quick response. ... View more

To setup a ISATAP tunnel, ISATAP server should send RA (a prefix) with a non-zero lifetime to the client, so that the client will treat this route as default route. Once the tunnel is built up, the default route pointing to server is available. But after the lifetime, the route disappears and never come back. How to figure this out? ... View more
