Server Default Gateway Configuration

The default gateway for a server is a Layer 3 device located in the aggregation layer of the data

center. This device can be a firewall, a load balancer, or a router. Using protocols such as HSRP

protects the gateway from being a single point of failure and creates a highly available data center

network. HSRP allows the two aggregate switches to act as a single, virtual router by sharing a

common MAC and IP address between them. Define a SVI on each aggregate switch and use the

HSRP address as the default gateway of the server farm.

Configure aggregation 1 as the active HSRP router. The priority command helps to select this

router as the active router because it has a greater value.
