Edge Connection Between Border and External Devices
NDFC enables seamless interconnection between two fabrics using edge connections based on BGP. This approach leverages two built-in NDFC policies: bgp_peer_template_dci_underlay_jython and ebgp_underlay_dci_template. These policies automate the creation of BGP peer templates by specifying neighbor information, adding the appropriate neighbor statements under the fabric ASN, and configuring source interfaces—including IP addresses and related parameters.
