IPv6 Neighbor Discovery cache resiliency to IPv6 unicast addresses getting recycled
This file contains hidden or bidirectional Unicode text that may be interpreted or compiled differently than what appears below. To review, open the file in an editor that reveals hidden Unicode characters.
Learn more about bidirectional Unicode characters
| Here is a trace showing that the IPv6 Neighbor Discovery process is resilient to IPv6 unicast addresses being recycled, | |
| because of the use of the "override" flag ("ovr", or "o-bit") in IPv6 Neighbor Advertisements. | |
| In the tshark trace below, a kubernetes pod with IPv6 address 2001:101::2 is trying to ping a pod at 2001:101::3. | |
| However, the previous pod that had been assigned the address 2001:101::3 has just been deleted, and a new pod was brought | |
| up using the same address. After several seconds of ping failure (trying to ping the now-deleted pod), the ping requestor | |
| sends a Neighbor Solicitation for 2001:101::3. The new pod with the this address then responds with a Neighbor Advertisement | |
| with the "ovr" (override) flag set (line 15 in the tshark output) indicating that any Neighbor Discovery cache entries for | |
| this address should be overwritten with the new pods link layer address. | |
| [kube@kube-minion-1 ~]$ sudo tshark -i cbr0 |
