Configuring Connectivity for OSPF Topology Acquisition

date_range 17-Oct-23
arrow_backward
arrow_forward

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.
    content_copy zoom_out_map
    [edit policy-options]
user@csd_topology_junosvm# set policy-statement TE term 1 from family traffic-engineering 
user@csd_topology_junosvm# set policy-statement TE term 1 then accept
  2. Populate the traffic engineering database.
    content_copy zoom_out_map
    [edit]
user@csd_topology_junosvm# set protocols mpls traffic-engineering database import policy TE
  3. Configure OSPF.
    content_copy zoom_out_map
    [edit]
user@csd_topology_junosvm# set protocols ospf area area interface interface interface-type p2p

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.
    content_copy zoom_out_map
    [edit interfaces]
user@csd_topology_junosvm# set gre unit 0 tunnel source local-physical-ip 
user@csd_topology_junosvm# set gre unit 0  tunnel destination destination 
user@csd_topology_junosvm# set gre unit 0  family inet addresstunnel-ip-addr 
user@csd_topology_junosvm# set gre unit 0  family iso 
user@csd_topology_junosvm# set gre unit 0  family mpls
  3. Enable OSPF traffic engineering on the JunosVM and add the GRE interface to the OSPF configuration.
    content_copy zoom_out_map
    [edit protocols ospf]
user@csd_topology_junosvm# set traffic-engineering 
user@csd_topology_junosvm# set area area interface gre.0 interface-type p2p 
user@csd_topology_junosvm# set area area interface gre.0 metric 65530
