option policy-filter
ip-address ip-address [, ip-address ip-address ...];
This option specifies policy filters for non-local source routing. The
filters consist of a list of IP addresses and masks which specify
destination/mask pairs with which to filter incoming source routes.
Any source routed datagram whose next-hop address does not match
one of the filters should be discarded by the client.
option max-dgram-reassembly
uint1
6;
This option specifies the maximum size datagram that the client
should be prepared to reassemble. The minimum value legal value is
576.
option default-ip-ttl
uint
8;
This option specifies the default time-to-live that the client should use
on outgoing datagrams.
option path-mtu-aging-timeout
uint3
2;
This option specifies the timeout (in seconds) to use when ageing Path
MTU values discovered by the mechanism defined in RFC 1191.
option path-mtu-plateau-table
uint16 [, uint16 ...
];
This option specifies a table of MTU sizes to use when performing
Path MTU Discovery as defined in RFC 1191. The table is formatted as
a list of 16-bit unsigned integers, ordered from smallest to largest. The
minimum MTU value cannot be smaller than 68.
option interface-mtu
uint1
6;
This option specifies the MTU to use on this interface. The minimum
legal value for the MTU is 68.
option all-subnets-local
fla
g;
This option specifies whether or not the client may assume that all
subnets of the IP network to which the client is connected use the
same MTU as the subnet of that network to which the client is directly
connected. A value of 1 indicates that all subnets share the same MTU.
A value of 0 means that the client should assume that some subnets of
the directly connected network may have smaller MTUs.
option broadcast-address ip-addres
s;
This option specifies the broadcast address in use on the client’s
