In PPPoE dual-chassis environment without the redundant-interface in place, SRRP aware routing should always be used. Otherwise, if the downstream traffic arrives on the standby node (SRRP backup state), it is forwarded directly to the client over the access network (assuming that the access network is operational) with the source MAC address of the group interface (instead of gw-mac). This grp-if MAC address is different from the MAC address (gw-mac) negotiated during the initial PPPoE phase, and therefore, this traffic is dropped by the client. It must be ensured that the downstream traffic is always attracted to the active node (SRRP master state) in the absence of redundancy.
