Configuring Connectivity for OSPF Topology Acquisition

If BGP-LS is not being used, one of the IGP protocols must be configured on the CSD-Topology. To enable OSPF on CSD-Topology, before you begin, verify IP connectivity between a switch (or router) and the x86 appliance on which CSD-Topology software is installed.

To configure OSPF topology acquisition, see:

Configuring OSPF on the CSD-Topology

To configure OSPF on the CSD-Topology:

  1. Configure the policy.
  2. Populate the traffic engineering database.
  3. Configure OSPF.

Configuring OSPF Over GRE on the CSD-Topology

Once you have configured OSPF on the CSD-Topology, you can take the following additional steps to configure OSPF over GRE:

  1. Initiate an SSH or telnet session using the IP address for the CSD-Topology JunosVM external IP address.
  2. Configure the tunnel.
  3. Enable OSPF traffic engineering on the JunosVM and add the GRE interface to the OSPF configuration.
