Understanding
The Orbit MCR can forward IP packets between routed interfaces, using a network path defined by the
user. These user-defined network paths are known as static routes. A static route may be configured if
data intended for a specific subnet or IP address must egress a particular onboard NIC.
As an example, consider a case where the unit is connected to a local network, 10.10.0.0/24, through its
ETH2 port. This network contains a gateway at IP address 10.10.10.101. This gateway is also connected
to another network 216.171.112.0/24, which has a NTP server. The Orbit MCR must use this network
path to access an NTP server at IP address 216.171.112.36. A static route to network 216.171.112.0/24
via next-hop 10.10.10.101 (or a host-only route to 216.171.112.36/24 via next-hop 10.10.10.101) ensures
that the unit can communicate with the NTP servers.
