Existing stateless redundancy, described in Data-triggered subscriber creation, is enhanced to support WLAN-GW based failure detection and switchover based on monitor and export route mechanism described above. The AP is not required to be configured with different tunnel endpoint addresses for active and standby WLAN-GWs. Single tunnel endpoint address is configured on the APs. The tunnel endpoint address is only announced in routing by the primary WLAN-GW as described in the section above. This form of redundancy as described in Data-triggered subscriber creation, required L2-aware NAT. After failure, the subscriber on the standby WLAN-GW that transitions to primary is based on data-triggered authentication. This is supported for both ESM and DSM.
