Deploying BGP Underlay in Enterprise SONiC: Peer Templates, Authentication, and BFD

Networking 5 min read

In modern data center networks, the Border Gateway Protocol (BGP) has emerged as a preferred routing protocol for building scalable and resilient underlay networks. As someone who’s implemented numerous data center fabrics, I’ve found that BGP’s flexibility and extensive feature set make it particularly well-suited for CLOS architectures. Enterprise SONiC, with its robust BGP implementation, […]

DHCP Relay Configuration in Enterprise SONiC

Networking 6 min read

In modern data center networks, Dynamic Host Configuration Protocol (DHCP) plays a critical role in automating IP address assignment to network devices. However, DHCP’s reliance on broadcast traffic creates challenges in routed environments where broadcast domains are separated by Layer 3 boundaries. This is where DHCP Relay becomes essential. As someone who’s implemented DHCP Relay […]
