Using Option 60 Information to Forward Client Traffic to Specific DHCP Servers
You can configure the extended DHCP relay agent to use the DHCP vendor class identifier option (option 60) in DHCP client packets to forward client traffic to specific DHCP servers. This feature is useful in network environments where DHCP clients access services provided by multiple vendors and DHCP servers. For example, a DHCP client might gain Internet access from a particular DHCP server provided by one vendor, and access IPTV service from a different DHCP server provided by another vendor. The option 60 string enables vendors to include vendor-specific information in DHCP client packets.
You can configure option 60 support globally or for a named group of interfaces. You can also configure option 60 support for the extended DHCP relay agent on a per logical system and per routing instance basis.
To configure the DHCP relay agent to use option 60 vendor-specific information to select a DHCP server to which to forward the client packets:
- Specify that you want to configure option 60
support. [edit forwarding-options dhcp-relay]user@host# edit relay-option-60
- (Optional) Configure the DHCP relay to
use matching option 60 strings to process client traffic.
See Using Matching Option 60 Strings to Process DHCP Client Traffic.
- (Optional) Configure the DHCP relay to use nonmatching
option 60 strings to process client traffic.
See Using Nonmatching Option 60 Strings to Process DHCP Client Traffic.
- (Optional) Display a count of the number of discarded
packets with option 60 information.
See Displaying a Count of Discarded DHCP Packets with Option 60 Information.
