Link Window Fields
This topic describes router-specific fields in the node, link, interface, demand, and tunnel tables as well as the Application Options windows.
Table 1: Modify Link, Properties Tab / View Link, General Tab
Link metric as seen by tunnels. Defaults to IGP metric if not specified.
The OSPF routing instance or process ID associated with this link.
Table 2: Location Tab
Interface name for source and destination nodes
IP Address and Mask of interface A and interface Z
Modify Link, Multicast Tab / View Link, Protocols Tab
SM : Sparse Mode
DM : Dense Mode
SDM :Sparse-Dense Mode
Table 3: MPLS/TE Tab
FRR A / FRR Z
no/yes: Specifies if there is a fast reroute backup tunnel for the Node A to Node Z direction, or vice versa.
If yes, specify the fast reroute backup tunnel.
Auto Bypass Parameters
GLB Pool / RSVP
Tunnels cannot route over a link unless there is available bandwidth in the global pool.
SUB Pool / GB
“Guaranteed bandwidth” tunnels cannot route over a link unless there is available bandwidth in the subpool.
The following protocols can be enabled or disabled in the Protocol tab by selecting “yes” or “no” in the dropdown box to the right of the corresponding protocol: MPLS, OSPF, ISIS, EIGRP, IGRP, RIP, LDP, TDP. After enabling a protocol on a link, the corresponding metric (if applicable) can be set underneath the A-Z Metric and Z-A Metric columns, such as the tunnel metric for MPLS-TE and the cost for OSPF, ISIS1 and ISIS2. The metric for a given IGP protocol will be used for routing the demands if the default routing protocol is set to that protocol in the Tools > Options > Design, Path Placement options pane, Routing Method option.
Note that there are two additional entries, Metric Bandwidth and (E)IGRP delay that can also used to influence the routing metric. The Metric Bandwidth is an informational and routing parameter corresponding to the “bandwidth” statements for Cisco and Juniper interfaces. The (E)IGRP delay corresponds to the “delay” statement for Cisco interfaces.
EIGRP and IGRP metrics can be influenced by changing the Metric Bandwidth or EIGRP Delay fields. Additionally, K-values can be set from the dparam file. To change the K-values from the text file before opening the network, the following line can be added to or edited in the dparam file:
For OSPF, the Metric Bandwidth will be used to calculate the routing metric only if no cost is specified. The reference bandwidth can be changed in Modify mode for Nodes in the IP tab.
For more details on the Protocols tab, see NorthStar Planner Routing Protocols Overview.
Tunnels can be prevented from routing over particular links if the link attributes, tunnel mask, and tunnel affinity are set.
CoS Policy Tab
Specify the CoS policy attached to the interface of node A (source) or node Z (destination). .
PBR (Policy Based Routing) Tab
Lists the route maps used for policy based routing. For more details on PBR..
