dhcp

The video looks into two additional methods of assigning IP address to Cisco ASA AnyConnect VPN client; using DHCP and RADIUS, in addition to the most popular local address pool. We will be using a Windows 2008 DHCP server and Cisco ACS 5.5 RADIUS server in this lab. 

The video presents an alternative to assigning IP address to DMVPN spoke tunnel interface using a centralized DHCP server. We look at this feature in a dual-hub environment, point out some routing caveats with return DHCP packet to the router acting as a relay agent, and a quick resolution.

The video walks you through DHCP configuration on Cisco router and switch for both server and client roles, how to exclude blocks of IP from a pool, and reserve IPs for certain hosts. We then look at DHCP relay (UDP unicast forwarding) used when the DHCP server is not situated on the same client subnet, and the significant of DHCP Option 82. Wireshark captures of DHCP packets are reviewed throughout the video.
