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:
- Configure the policy.[edit policy-options]user@csd_topology_junosvm# set policy-statement TE term 1 from family traffic-engineeringuser@csd_topology_junosvm# set policy-statement TE term 1 then accept
- Populate the traffic engineering database.[edit]user@csd_topology_junosvm# set protocols mpls traffic-engineering database import policy TE
- Configure OSPF.[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:
- Initiate an SSH or telnet session using the IP address for the CSD-Topology JunosVM external IP address.
- Configure the tunnel.[edit interfaces]user@csd_topology_junosvm# set gre unit 0 tunnel source local-physical-ipuser@csd_topology_junosvm# set gre unit 0 tunnel destination destinationuser@csd_topology_junosvm# set gre unit 0 family inet addresstunnel-ip-addruser@csd_topology_junosvm# set gre unit 0 family isouser@csd_topology_junosvm# set gre unit 0 family mpls
- Enable OSPF traffic engineering on the JunosVM and add
the GRE interface to the OSPF configuration.[edit protocols ospf]user@csd_topology_junosvm# set traffic-engineeringuser@csd_topology_junosvm# set area area interface gre.0 interface-type p2puser@csd_topology_junosvm# set area area interface gre.0 metric 65530
