Internetworking and Management Overview
Campus-REX RS Interface Card User Manual
7-7
Configure a Static Route entry in any of the external routers that may have
been specified as a Default Router IP address or as a Gateway address in the
Campus-REX. This is required because the Campus-REX does not send
periodic route updates using protocols like Routing Information Protocol
(RIP) or Open Shortest Path First (OSPF) so that other external routers can
automatically update their routing tables. This implementation prevents other
Parameter
Definition
Bridge/Router Mode
Select Bridge or Router. Both Campus-REX units connected
through the HDSL link must be configured as routers for
static routing to work.
Packet Encapsulation
Select either PPP or HDLC.
You must set both Campus-REX
units connected through the HDSL link to the same
encapsulation option. For static routing, set this option to
HDLC.
Default Router IP Address
Specifies the next hop default router entry.
This entry tells the
Campus-REX what to do with a packet that has a destination
address that is not in the Static IP Routing table.
IP Static Routing Table
Specify up to three static route entries, where each entry
includes: destination Subnet or host IP address, destination
Subnet Mask, and the IP address of the next-hop Gateway to
which the packet should be sent.
When you configure the
remote end of a point-to-point HDSL connection, you can
leave this table blank and specify a single default router IP
address since all packets will be forwarded to the other end
of the connection.
Or for security, you can choose to fill in the
table.
LAN IP Address and
Subnet Mask
Enter the IP address and subnet mask for the LAN Port
(10BASE-T port).
These must be configured for static IP
routing to function properly.
Line IP Address and
Subnet Mask
Enter the IP address and subnet mask for the Line Port
(HDSL port).
These must be configured for static IP routing
to function properly.
When you configure a point-to-point
system, the Line IP address of both units must belong to the
same IP subnet and the Line Subnet Mask parameters for
both units must be the same.
The Line IP Address and
Subnet Mask for a point-to-point system are isolated and
hidden from the rest of the network—you may use any
subnet.
