TSAT 3000 Configuration Parameter Description, January 2013 Page 45 of 124
<mask>: The Network Mask is also a 32 bit unsigned integer, with the restriction that
all upper bits should be “1”, while all lower bits should be “0”. Normally, you
just specify the number of upper “1” bits. Ex: “24”. However, it’s also possible
to specify <number> or <dot-notation>. Ex: “0xFFFFFF00” or
“255.255.255.0”. CCU will generate a default Network Mask when <mask> is
omitted in configuration:
• 0xFFFFFF00 (i.e. 24 bits) when Gateway is specified.
• 0xFFFFFFF0 (i.e. 28 bits) when Gateway is zero – i.e. Default Routes.
<gateway>: The Gateway is an IP Address with the same syntax as Destination. All
packets to IP Addresses matching the Destination Network Address will be
routed to the specified Gateway. The special value “0.0.0.0” (or just “0”) will
make CCU to generate a set of default Routes, as specified further down.
<flags>: The Flags is also a 32 bit unsigned integer, specified as a <number>. The
following options are used by the IP-STACK:
RTF_UP 0x0001 // route usable
RTF_GATEWAY 0x0002 // destination is a gateway
RTF_HOST 0x0004 // host entry (net otherwise)
RTF_REJECT 0x0008 // host or net unreachable
RTF_DYNAMIC 0x0010 // created dynamically (by redirect)
RTF_MODIFIED 0x0020 // modified dynamically (by redirect)
RTF_DONE 0x0040 // message confirmed
RTF_MASK 0x0080 // subnet mask present
RTF_CLONING 0x0100 // generate new routes on use
RTF_XRESOLVE 0x0200 // external daemon resolves name
RTF_LLINFO 0x0400 // generated by ARP or ESIS
RTF_STATIC 0x0800 // manually added
RTF_BLACKHOLE 0x1000 // just discard packets (during updates)
RTF_PROTO2 0x4000 // protocol specific routing flag
RTF_PROTO1 0x8000 // protocol specific routing flag
RTF_MGMT 0x2000 // modified by management proto
RTF_REP_NODE 0x4000 // Representative Node in the Pat tree
RTF_CLONED 0x4000 // Child route holding path MTU results
RTF_DELETE 0x8000 // Unused route scheduled for deletion
The CCU will always apply the RTF_STATIC (0x0800) option when Route is
added.
Default Route
CCU will generate a set of default Routes when Gateway is zero (“0.0.0.0” or just “0”).
