The value of tmnxVdoIfRTClientAddr specifies the IP address for the
retransmission (RT) client in the video interface within the service.
The RT client IP address is the originating address used for
communication with upstream RT servers. If no RT client address is
assigned, the RT client is operationally down as the RT client
configuration is incomplete.
For a VPLS service, the RT client address cannot be the same as an
existing address for the video interface, but it must be an address
within a video interface subnet. For IES and VPRN services, the RT
client address can be the same as an existing address for the video
interface or an address within a video interface subnet.
