Destination Mask TOS Gateway Flags RefCnt Use Interface Proto
0.0.0.0 0 0 10.0.0.1 803 0 196587 esmc0 1
Any IP packet with a destination which is not listed in the Routing Table will be forwarded
through the Ethernet port (IP address 10.0.0.1) and on to the NAP router.
The radio subnet route is defined by:
Destination Mask TOS Gateway Flags RefCnt Use Interface Proto
10.5.0.0 ffff0000 0 10.5.0.1 101 0 0 rdr1 0
Any IP packet destined for the radio subnet (any IP address starting with 10.5.xx.xx) will be
forwarded through the CCU radio port (IP address 10.5.0.1) and over the radio link to the
EUMs and end-user’s computers.
The loopback route is defined by:
Destination Mask TOS Gateway Flags RefCnt Use Interface Proto
127.0.0.1 0 0 127.0.0.1 5 0 24 lo0 0
Any IP packet destined for 127.0.0.1, which is an IP address reserved for loopback, will be
looped back to the CCU operating system.
The Routing Table flags are summarized in Table 52 .
Table 52 Routing Table Flags.
To use Table 52 , consider the flag associated with the default route, 803, which is equal to
