DHCP Service Creation
Use the following example to create the DHCP service to support DHCP-based address assignment:
configure
context <
dest_ctxt_name
>
dhcp-service <
dhcp_svc_name
>
bind address <
ip_address
> [nexthop-forwarding-address <
nexthop_ip_address
>
[mpls-label input <
in_mpls_label_value
> output <
out_mpls_label_value1
>
[
out_mpls_label_value2
]]]
end
Notes:
To ensure proper operation, DHCP functionality should be configured within a destination context.
Optional keyword
nexthop-forwarding-address
<
nexthop_ip_address
>
[mpls-label input
<
in_mpls_label_value
>
output
<
out_mpls_label_value1
>
[
out_mpls_label_value2
]]
applies
DHCP over MPLS traffic.
DHCP Server Parameter Configuration
Use the following example to configure the DHCP server parameters to support DHCP-based address assignment:
configure
context <
dest_ctxt_name
>
dhcp-service <
dhcp_svc_name
>
dhcp server <
ip_address
> [priority <
priority
>
dhcp server selection-algorithm {first-server | round-robin}
lease-duration min <
minimum_dur
> max <
max_dur
>
dhcp deadtime <
max_time
>
dhcp detect-dead-server consecutive-failures <
max_number
>
max-retransmissions <
max_number
>
retransmission-timeout <
dur_sec
>
end
Notes:
Multiple DHCP can be configured by entering
dhcp server
command multiple times. A maximum of 20
DHCP servers can be configured.
The
dhcp detect-dead-server
command and
max-retransmissions
command work in conjunction with
each other.
