Configuring the vLAG ignore split option
This procedure is for LACP-based vLAGs. The scope of this configuration is per port-channel. In
scenarios where the vLAG spans more than one node, it minimizes the extent of packet loss in the
event of one of the nodes in the vLAG going down.
In a case where connectivity between nodes is lost due to a fabric split (as opposed to one of its
members going down), duplication of multicast/broadcast packets will occur.
Brocade recommends that you build redundancy in the fabric so that individual links are not single
points of failure.
displays a dual vLAG configuration with three legs of RB2, RB3, and RB4. If RB2, RB3, or
RB4 reboots while Host-1 is communicating to Host-2 or Host3, a momentary traffic disruption may
occur.
