1. A system comprising:
a first top-of-rack (ToR) switch; and
a second ToR switch, the second ToR switch to:
receive a network packet from a first host, the network packet to include a destination address of a second host; and
after a failure of a physical network interface card (pNIC) at the second host eliminates a first link between the second host and the second ToR switch, send the network packet to the first ToR switch via an inter-switch link between the first and second ToR switches to cause the first ToR switch to forward the network packet to the second host via a second link between the first ToR switch and the second host.
