Telnet and CLI Operation
9.2.2.3 Route Table Configuration screen
Go to the Route Table Configuration screen from the Main Menu.
CAUTION
Do not operate a CDM-IP modem satellite link where both IP modems have a Default
Route to the satellite.
About the CAUTION note: if both IP modems had this Route Table entry:
IP Dest
0.0.0.0/0
Any traffic forwarded by an IP modem that did not have a valid IP host at the remote LAN would then be
resent by the remote IP modem. This traffic would continue to be forwarded until the TTL expired. This
"routing loop" limits the performance of the IP modem by wasting satellite bandwidth.
