Configuring Detection of DHCP Relay or DHCP Relay Proxy Client Connectivity
Liveness detection for DHCP subscriber IP or DHCP client IP sessions utilizes an active
liveness detection protocol to institute liveness detection checks for relevant clients.
Clients must respond to liveness detection requests within a specified amount of time.
If the responses are not received within that time for a given number of consecutive
attempts, then the liveness detection check fails and a failure action is implemented.
To configure liveness detection for DHCP relay:
1. Specify that you want to configure liveness detection.
•
For DHCP global configuration:
[edit forwarding-options dhcp-relay]
user@host# edit liveness-detection
•
For DHCP group configuration:
[edit forwarding-options dhcp-relay group group-name]
user@host# edit liveness-detection
NOTE: Liveness detection is also supported for DHCPv6 configurations.
To configure DHCPv6 liveness detection, include the liveness-detection
statement, and any subsequent configuration statements, at the [edit
forwarding-options dhcp-relay dhcpv6] or [edit forwarding-optionsdhcp-relay
dhcpv6 group group-name hierarchy level.
2. (Optional) Specify that you want to use DHCP relay proxy mode.
[edit forwarding-options dhcp-relay group group-name]
user@host# set overrides proxy-mode
