ipv6/settings
Type: Settings Directory
This menu allows you to configure various IPv6-related kernel and system-wide network parameters. These settings control how the operating system handles IP traffic and network communications.
note
Changing IPv6 settings does not dynamically remove an existing SLAAC configuration. A router reboot is required for changes to take effect.
| Argument | Type | Description |
|---|---|---|
| disable-ipv6 | bool | Disable or enable IPv6 system-wide. When disabled, prevents link-local address generation. |
| forward | bool | Enable or disable packet forwarding between interfaces. |
| multipath-hash-policy | enum (l3 | l4 | l3-inner) | Specify the IPv6 hash policy for ECMP routing:
|
| accept-redirects | bool | Accept or reject ICMP redirect messages. Enable on hosts and disable on routers. |
| accept-router-advertisements | enum (no | yes-if-forwarding-disabled | yes) | Control acceptance of router advertisement (RA) messages. When enabled, the router obtains addresses using stateless address configuration. |
| accept-router-advertisements-on | enum | Specify which interfaces to listen for incoming router advertisements (RAs). |
| disable-link-local-address | bool | Disable automatic link-local address generation for non-VPN interfaces. Use this when you need manually configured link-local addresses. |
| stale-neighbor-detect-interval | num | Set the interval at which the system checks stale IPv6 neighbor entries and probes them to verify reachability. |
| stale-neighbor-timeout | num | Timeout duration after which stale IPv6 neighbor entries are purged. |
| min-neighbor-entries | num | Set the minimum number of IPv6 neighbor entries for which the device must allocate memory. |
| soft-max-neighbor-entries | num | Set the expected maximum number of IPv6 neighbor entries the system should handle. |
| max-neighbor-entries | num | Set the maximum number of IPv6 neighbor entries. As of RouterOS version 7.1, the default value depends on installed RAM:
Setting a value higher than the default increases the risk of out-of-memory conditions. |
| allow-fast-path | bool | Enable Fast Path for IPv6 traffic. |
Fasttrack and fastpath values are cumulative since the feature was last enabled or since the system restarted.
| Read-only Argument | Type | Description |
|---|---|---|
| ipv6-fast-path-active | bool | Indicates whether the IPv6 fast path feature is currently active. |
| ipv6-fast-path-packets | num | Total number of packets that have been processed through the IPv6 fast path. |
| ipv6-fast-path-bytes | num | Total number of bytes that have been processed through the IPv6 fast path. |
| ipv6-fasttrack-active | bool | Indicates whether the IPv6 fasttrack feature is currently active. |
| ipv6-fasttrack-packets | num | Total number of packets that have been processed through IPv6 fasttrack. |
| ipv6-fasttrack-bytes | num | Total number of bytes that have been processed through IPv6 fasttrack. |
