Hi, (Apologies for not quoting, etc as I don't have the original email in my mailbox)
Too bad that 5.6 seems 'buggy' ... some of it's new features look nice, and I was planning to put it on a new box... now I'm not so sure about that any longer... Also interesting that you seem to run 5.5d without problems, as we came across a bug in 5.5 with regards to the IPv6 route cache - DEFECT000500944 Due to it's characteristics, my guess would be that we really can't be the only one that faced that problem ? :) The issue is that after a link between 2 MLXe's fails and the IGP selects a different path ... it fails to update the IPv6 cache. However, it updates the RIB, etc correctly .... so IPv6 traffic transiting through the router appears to keep working without issue and everything _seems_ correctly (even from looking at CAM), only traffic originated from the router itself (eg. loopback) is still pointing to the wrong interface, which for example affected IPv6 iBGP sessions in our case. The provided method to resolve it is to manually clear the IPv6 cache by running "clear ipv6 cache" (Note that 'cache' is hidden in the outout from "clear ipv6 ?" ... DEFECT000503937) According to TAC, this issue occurs in both 5.5.x and 5.6.x ... and both with IS-IS and OSPF. In our case, this was on MLXe-4's with 4x10G X-blades, running IS-IS, with v5.5d and v5.5e Fix should come in 5.6d .. not sure in what version 5.5 will be fixed. Just wondering if anyone else faced this as well ?
