ICX 6610 IPv6 neighbour cache

dooh — Sat, 14 May 2022 00:16:53 GMT

Hi there,

We are using a couple of ICX6610 stacks with ADV ROUTER SOFTWARE PACKAGE and we encounter issues regarding the IPv6 neighbour cache. The stacks are default gateways to a couple of VMware clusters and when we migrate machines between nodes, the IPv6 neighbour cache remains untouched and we need to do a clear ipv6 neighbour vrf aaaa:bbbb and clear ipv6 cache vrf aaa:bbbb.

We are using firmware 08.0.30tT7f3 and 08.0.30m, both do manifest in the same way.

http://docs.ruckuswireless.com/fastiron/08.0.60/fastiron-08060-commandref/GUID-8298B9EF-5CC8-44E2-834B-305F6B8E3030.html says about ipv6 cache-lifetime but we tried changing ipv6 cache-lifetime to 1 or ipv6 cache-lifetime whatevernumber and does not help, issue remains.

Do any of you encountered this issue or have any ideea?

It is hard to say on this. I would advise opening a support case (see my signature), so somebody can properly investigate.

Thank you Ben. Our devices are way out of warranty and out of support, but if this a suspect case and you'd wish, I can open a ticket.

Did you ever figure this out?

I have an ICX7250 and I'm running into the same issue with WAP clients and roaming.

If I issue the same clear ipv6 command things start working again.
