5. When you have filled in the fields, choose OK to configure the VNN OSPF virtual
link.
The Add VNN Virtual Link dialog box closes.
Configuring VNN OSPF External Route Aggregates
Configuring VNN OSPF external route aggregates allows the VNN OSPF on a Lucent
switch to aggregate Autonomous System External link state advertisements (ASE
LSAs) for routes learned from another autonomous system via another routing
protocol, such as BGP. This can reduce the number of ASE LSAs that need to be
installed in the VNN OSPF database, thereby minimizing memory and CPU usage.
Configuring VNN OSPF External Route Aggregates
To configure VNN OSPF external route aggregates:
1. Expand the instance node for the switch to which you want to add a VNN OSPF
external route aggregation.
2. Expand the VNN class node.
Neighbor Router
ID
Enter the router D (IP address) of the switch (that is, the neighbor) on
the other end of the virtual link. The router ID IP address is
configured when the switch is installed. To determine the internal IP
address, access the switch console and issue the show system
command. In the command output, the internal IP address appears in
the Internal IP Addr field. For example:
Internal IP Addr: 150.202.77.2
In this example, the internal IP address is 150.202.77.2.
