DSL Card Static Route Example

6-4
The following illustration shows an example of how static routes configured on a
DSL card are used in its routing table:
NSP Router
155.1.2.2/ 155.1.2.1/
255.255.0.0 255.255.0.0
155.1.3.1/
255.255.255.0
*If DSL card is an 8540 DSL card,
associated RTU will not have an IP address.
DSL Routing Table
Host/Net Subnet Mask
1) 155.1.3.4 255.255.255.255
2) 135.1.2.0 255.255.255.0
3) 0.0.0.0 0.0.0.0
In this example:
The DSL card's Ethernet port is connected to the router's port, which has an
IP address of 155.1.3.1.
Packets being routed in the upstream direction (to an NSP) would use the
third routing table entry; i.e., Host/Net IP address 0.0.0.0 (by definition) and a
Next Hop address of 155.1.3.1.
They would use this route because no other destination would match.
The management domain IP address of the RTU is 135.1.3.3 and the IP
address of the ES is 155.1.3.4. Packets being routed downstream use the
first routing table entry, i.e., Host/Net IP address of 155.1.3.4 and a Next Hop
address of 135.1.3.3. Note that this is a host route.
The second routing table entry is for upstream routing to the NMS via the
MCC card. Note that this is a subnet route.
