Abstract
A first network device advertises routes of locally connected routes/subnetworks based on the connectivity of the host with respect to peer network devices. The first network device establishes a virtual port channel associated with a virtual network address. The virtual port channel includes the first network device associated with a first network address and a second network device associated with a second network address. The first network device detects that a host is connected to the first network device and determines a next hop address to associate with the host. The next hop address is determined based on whether the host is also connected to the second network device of the virtual port channel. The first network device generates a route advertisement associating the next hop address with the host.
