Configuring basic DHCP snooping features in a VXLAN
network
In a VXLAN network, you can configure the following interfaces as DHCP snooping trusted
interfaces:
•
ACs that are mapped to a VSI.
•
VXLAN tunnel interfaces that are assigned to a VSI.
When the VTEP with DHCP snooping configured receives a DHCP request, the VTEP forwards this
request through the trusted ACs or VXLAN tunnel interfaces.
If the DHCP server is in the local site, configure the AC that connects to the DHCP server as trusted.
If the DHCP server is in a remote site, configure the VXLAN tunnel interface as trusted.
