A sample DC network configuration for the DC network using a vPC topology is shown in the following figure. This topology has multiple uplinks from the access to the core, and the uplinks are distributed on the uplink core switches. HSRP can be configured on the devices that act like the default gateways for the LAN segments. Since all segments would typically terminate on the firewall for security, the firewall would act as the default gateway for the LAN segments, and hence the gateway redundancy has to be built on the firewall.
The network is the underlying transport infrastructure for all packets on the network. Any failure on the network without a redundant path can lead to outages. There are a number of techniques useed ...
