• Centralized L3 DHCP scope - Virtual Controller acts as DHCP Relay agent• Centralized DHCP server - provides IP addresses for multiple networks• VC and DHCP server are located in different network• VC acts as gateway for the clients• Typical deployment model is DHCP server is behind a controller on corporate network, which can be reached through IPSec.Typical Scenario:---------------------• DHCP server is behind IPSec tunnel.• VC forwards DHCP requests through tunnel to reach DHCP server located at Corporate network • Route addition happens in controller for Centralized L3 network configured• Client traffic to non-corporate destinations will be src-natted on the IAP.Configuration from WEBUI:-----------------------------------From CLI:-------------- 6c:f3:7f:c3:5b:f8 (config) # ip dhcp cl36c:f3:7f:c3:5b:f8 (DHCP Profile "cl3") # server-type Centralized,L36c:f3:7f:c3:5b:f8 (DHCP Profile "cl3") # server-vlan 20036c:f3:7f:c3:5b:f8 (DHCP Profile "cl3") # dhcp-relay6c:f3:7f:c3:5b:f8 (DHCP Profile "cl3") # vlan-ip 172.16.4.7 mask 255.255.255.06c:f3:7f:c3:5b:f8 (DHCP Profile "cl3") # dhcp-server 172.16.6.1006c:f3:7f:c3:5b:f8 (DHCP Profile "cl3") # end6c:f3:7f:c3:5b:f8# commit applycommitting configuration...configuration committed.6c:f3:7f:c3:66:ca# show dhcps---- --------- -------------- -------------Other DHCP Scopes-----------------Name Type VLAN Network Netmask Exclude Address Default Router DNS Server Domain Name Lease Time DHCP Relay DHCP Relay Servers DHCP Option 82 DHCP Option VLAN IP VLAN Mask---- ---- ---- ------- ------- --------------- -------------- ---------- ----------- ---------- ---------- ------------------ -------------- ----------- ------- ---------cl3 Centralized,L3 2003 0.0.0.0 0.0.0.0 0.0.0.0 0.0.0.0 0.0.0.0 43200 ON 172.16.6.100 None 172.16.4.7 255.255.255.0
