dhcpkit.ipv6.extensions.sol_max_rt module¶
Implementation of SOL-MAX-RT and INF-MAX-RT options as specified in RFC 7083.
-
class
dhcpkit.ipv6.extensions.sol_max_rt.
InfMaxRTOption
(inf_max_rt: int = 0)[source]¶ Bases:
dhcpkit.ipv6.options.Option
A DHCPv6 server sends the INF_MAX_RT option to a client to override the default value of INF_MAX_RT. The value of INF_MAX_RT in the option replaces the default value defined in Section 3. One use for the INF_MAX_RT option is to set a longer value for INF_MAX_RT, which reduces the Information-request traffic from a client that has not received a response to its Information-request messages.
The format of the INF_MAX_RT option is:
0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | option-code | option-len | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | INF_MAX_RT value | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
- option-code
- OPTION_INF_MAX_RT (83).
- option-len
- INF_MAX_RT value
- Overriding value for INF_MAX_RT in seconds; MUST be in range: 60 <= “value” <= 86400 (1 day).
-
inf_max_rt
= None¶ The new value for INF_MAX_RT for the client
-
load_from
(buffer: bytes, offset: int = 0, length: int = None) → int[source]¶ Load the internal state of this object from the given buffer. The buffer may contain more data after the structured element is parsed. This data is ignored.
Parameters: - buffer – The buffer to read data from
- offset – The offset in the buffer where to start reading
- length – The amount of data we are allowed to read from the buffer
Returns: The number of bytes used from the buffer

SolMaxRTOption
(sol_max_rt: int = 0)[source]¶ Bases:
dhcpkit.ipv6.options.Option
A DHCPv6 server sends the SOL_MAX_RT option to a client to override the default value of SOL_MAX_RT. The value of SOL_MAX_RT in the option replaces the default value defined in Section 3. One use for the SOL_MAX_RT option is to set a longer value for SOL_MAX_RT, which reduces the Solicit traffic from a client that has not received a response to its Solicit messages.

load_from
(buffer: bytes, offset: int = 0, length: int = None) → int[source]¶ Load the internal state of this object from the given buffer. The buffer may contain more data after the structured element is parsed. This data is ignored.
Parameters: - buffer – The buffer to read data from
- offset – The offset in the buffer where to start reading
- length – The amount of data we are allowed to read from the buffer
Returns: The number of bytes used from the buffer

-
save
() → Union[source]¶ Save the internal state of this object as a buffer.
Returns: The buffer with the data from this element

sol_max_rt
= None¶ The new value of SOL_MAX_RT for the client
