Bug ID 454498: DHCP virtual will not forward DHCP broadcast traffic

Last Modified: May 29, 2024

Affected Product(s):
BIG-IP LTM(all modules)

Known Affected Versions:
11.6.0, 11.6.1, 11.6.2, 11.6.3, 11.6.3.1, 11.6.3.2, 11.6.3.3, 11.6.3.4, 11.6.4, 11.6.5, 11.6.5.1, 11.6.5.2, 11.6.5.3

Opened: Mar 28, 2014

Severity: 3-Major

Symptoms

If DHCP virtual was configured to work in forwarding mode, it drops all broadcasting (i.e., coming from source 0.0.0.0 and going to 255.255.255.255) DHCP traffic. This applies on both protocols DHCPv4 and DHCPv6 in the 11.6.0 release. If you want to support broadcasting DHCP traffic, then the DHCP virtual has to be configured in Relay mode rather than Forwarding mode.

Impact

DHCP broadcast traffic is not forwarded.

Conditions

This occurs on DHCP virtuals configured in forwarding mode.

Workaround

None
