Overview
Use this command to set the tunnel mode to OpenVPN TAP for a tunnel interface.
Use the
no
variant of this command to remove the mode.
TAP is a virtual network device. TAP creates a Virtual Tunnel Interface (VTI) that
carries layer 2 frames. You may want to use TAP in the following scenarios:
•
You want to use bridges to transport Ethernet frames
•
You want to transport any network protocol, such as IPv4, IPv6, IPX
Note that TAP will cause broadcast overhead on the VPN tunnel and add the
overhead of Ethernet headers on all packets transported over the VPN tunnel.
Note that the distribution of client IP addresses through DHCP is only supported in
TAP mode.
