Abstract
Methods, computer-readable media, and systems are disclosed for coordinating host link status and installation of egress filters in coordination with a multi-chassis link aggregation group (MLAG) peer. In response to receiving a request from an MLAG peer to install an egress filter, a local network device provides an indication that the local device has entered a local egress filter installed state. Next, a filter-installed watermark value associated with the local network device is incremented. The local network device provides an indication that the egress filter has been installed. Finally, in response to determining that the MLAG peer network device is not indicating a request peer to install filter status, a local network device indicates a link down status and uninstalls its local egress filter. Alternatively, in response to determining that the local network device is in a link up status, the local device indicates that an MLAG peer should install an egress filter. In response to determining that the peer network device is in a filter request status, installing a local egress filter.
