nd-cache disable
Use this command to disable ND cache for MAC/IPv6.
When the ND cache is disabled on an Access Circuits, It does not reply to any ND arriving on this port from the cache. It withdraws all MAC/IPs configured/learned on this Access Circuit and removes the MAC/IP entry for this AC from the local ND cache.
It also makes sure that on withdrawing the MAC/IP route, the MAC does not become unknown. If all routes for this MAC are being withdrawn because of this command, then it advertises a MAC-only route. This is done so that the MAC does not become unknown and only the cache functionality becomes disabled.
Use the no form of this command to enable ND cache for MAC/IPv6.
Note: On enabling the cache, an IP will be in conflict, then the cache enable will fail. The conflict has to be manually removed and then the cache enabled.
Note: Not applicable for the AC port which is mapped with ELINE/Xconnect Service.
