This helps ensure that in networks without IPv6 +traffic, resources are not wasted. If IPv6 traffic is present, especially +with large routing tables, you must allocate additional resources for IPv6 +processing to keep the dataplane stable. + +You can configure two main resources for IPv6 traffic processing: + +```{cfgcmd} set vpp settings resource-allocation ipv6 hash-buckets \ +``` + +This parameter configures the number of hash buckets used for IPv6 +routing. If you have a large IPv6 routing table, you may need to increase +this value to ensure efficient routing table performance and fast lookups. + +```{cfgcmd} set vpp settings resource-allocation ipv6 heap-size \ +``` + +This parameter configures the heap size used for IPv6 forwarding. If you +have a large IPv6 routing table, you may need to increase this value to +ensure the routing table can accommodate all routes. + +## Potential Issues and Troubleshooting + +Improper IPv6 configuration can lead to various issues, including: + +- Inefficient, slow routing table lookups and traffic processing due to + insufficient hash buckets +- Dataplane crashes or instability due to insufficient heap size when + handling a large number of IPv6 routes +- Overall dataplane instability when handling IPv6 traffic + +Consider increasing configuration values if you experience issues with +IPv6 traffic processing or if you have a large IPv6 routing table. -- cgit v1.2.3
