Table 6-5. IP Router Options (1 of 4)

Static Routes A-E-A
Gives the user the ability to add or delete static routes in the system. For the
management domain, static routes must be provided to the MCC and the RTUs. For the
service domain, static routes must be provided upstream to the next hop route and
downstream to those hosts that require static routes.
Item – Press Return on 0 field to add entry.
Host/Net –
nnn.nnn.nnn.nnn
format or space to delete entry. This field is read only for
dynamic routes.
Subnet Mask – Associated subnet mask for the specified destination IP address. On
Model 8540, 255.255.255.255 is the subnet mask for routes to the RTUs. This field is
read only for dynamic routes.
Next Hop –
nnn.nnn.nnn.nnn
format. On Model 8540, the next hop is DSL port name
s1c, s1d, s1e, or s1f. This field is read only for dynamic routes.
Pref – Measure of how preferable one route is to another, if you have two routes going
to the same destination. (The lower the number, the more preferable.) This route is
compared to others for the same address. This field is read only for dynamic routes.
S/D (Source/Destination) – Source or destination IP address of the packet. This field is
read only for dynamic routes.
PA (Proxy ARP) – Router answers ARP requests intended for another machine. This
field is read only for dynamic routes.
NOTE: When you define a source route, the Proxy ARP field is no longer
selectable.
Martian Networks A-E-B
Gives the user the ability to configure addresses that the system recognizes as invalid.
Item – Press Return on 0 field to add entry.
Martian Net ID –
nnn.nnn.nnn.nnn
format or space to delete entry. Enter IP address of
unwanted source.
Martian Net Mask –
nnn.nnn.nnn.nnn
format. Enter IP mask of unwanted source.
NOTE: The system is shipped with default martian networks. It is recommended
that you do not remove entries. If you have made changes to this screen,
you must do a card reset.
