s = Route Name up to 13 characters. It should be unique. Reusing of route
names with different index, will end up modifying the existing route.
d = Destination IP Address in xxx.xxx.xxx.xxx/yy where
xxx.xxx.xxx.xxx is IP address and
yy – Subnet mask bits. To mean ‘Any IP Address’ indicate it by
***.***.***.***/** format.
D = Destination Subnet Mask Bits.
i = Interface 1 – Sat and 0 – Ethernet
n = Next Hop IP Address in xxx.xxx.xxx.xxx format.
To be valid the next hop should be on the same subnet
as the router IP Address. This field will be all ‘*’ for a ‘SAT’ directed route. It
means, for a route with valid HDLC address this field will be ‘***************’.
h = HDLC Addr in 4-digit hexadecimal number. Valid
range is 0x00 to 0xFE in Router-Small Network mode.
And 0x0000 to 0x7FFE for Router-Large Network
mode. This field will be all ‘*’ for ‘ETH’ directed route.
It means, if the route has a valid next-hop, then this field is ‘****’ [meaning HDLC
Address is not Used.]. HDLC Address is not used in point-to-point mode, may
default to ‘1’.
t = Header Compression 0 – No 1 – Yes.
p = Payload Compression 0 – No 1 – Yes.
c = DES Encryption 0 – No 1 – Yes.
k = DES Key to use 0 – Don’t use any key 1 – 8 use as
mentioned and 9 – Use Random key.
S = Multicast state 0-None 1=Eth-to-Sat 2=Sat-to-Eth
3=toBoth
When called using an existing index, the command is treated as a “modify”. Only
new routes can be added at the END of the list:
Example: RTN?
RTN=3
<1/rte[3]= rt3|239.111.102.222.32|0|192.168.001.022|00AB|0|0|1|5|3
Sat Directed Route:
>0001/RTE[1]=rt1|011.012.013.014/32|1|***.***.***.***|1111|0|0|0|0|0
Eth Directed Route:
>0001/RTE[4]=rt4|012.013.014.015/32|0|192.168.001.111|****|0|0|0|0|0 RTE =
RTE!
RTE[1..256]? RTE[1..256] = xxx
