CTOG-250 Comtech Traffic Optimization Gateway Revision 1
Ethernet-based Remote Product Management MN-CTOG250
7–47
When enabled, CDRP automatically synchronizes the CTOG-250’s Route Table with all of the LAN
attached routes for every CDM-840 Remote Router that shares the CTOG-250’s Outbound
Carrier.
The CDM-840 LAN attached routes are:
• One route for the Traffic Ethernet Interface (same as the configured IP/Mask);
• One route for the Traffic Ethernet Interface (same as the configured IP/Mask);
• Any route in the CDM-840 that is configured “toLAN”.
With CDRP enabled, any user changes in the CDM-840 Route Table for LAN routes will be
automatically synchronized with the CTOG-250. CDRP routes are created in the CTOG-250 with
the WAN Label configured in WAN Label Entry #1 on a per-CDM-840 basis. In addition, if the
value of WAN Label Entry #1 is changed on the CDM-840, this change is automatically reflected
at the CTOG-250 for all associated routes so as to avoid any possibility of accidental user
omission.
Note that if CDRP is enabled, the WAN labels for the dynamic routes will come from the WAN
Label Entry #1 on each CDM-840 – however, they will not default to 1 (unless you have 1
configured in the remote CDM-840). These WAN labels must be unique across all of the
CDM-840s. Entries 2,3, or 4 will work, but are ignored as far as CDRP and BPM are concerned.
In order for CDRP to operate as expected, the following is required:
• The CDM-840 Demodulator is locked onto the CTOG-250/CDM-800 Carrier.
• Each CDM-840 has a unique WAN Label configured in WAN Label Entry #1.
o If these values are not unique, then the potential exists for packets to be sent to
multiple remotes and processed. This can result in duplicate packets as well as
reduced processing capacity for each CDM-840.
• Each CDM-840 has at least one of the following:
o A unique Traffic IP Address.
If the Management IP address is not re-configured from the factory
default, the protocol will detect this condition and use the Traffic IP
address.
o A unique Traffic and Management IP address (preferred).
If the IP Addresses are not unique, then CDRP will be unable to uniquely
differentiate these routes. As a result, not all routes will be created. Furthermore,
this is a requirement for a routed network to function.
