Configuring OSPF on a PE device to redistribute BGP-VPNv4 routes
To allow OSPF route exchange between a specified VRF on a PE device and its associated CE
device, OSPF must be configured to redistribute BGP routes from the local AS as described in the
following steps:
• “Defining an OSPF instance in a VRF”
• “Creating an OSPF area in an OSPF VRF instance”
• “Creating a domain identifier in an OSPF VRF instance”
• “Assigning a domain tag in an OSPF VRF instance”
Defining an OSPF instance in a VRF
NOTE
This features is not supported on Brocade NetIron CES or Brocade NetIron CER devices.
To define an OSPF instance in VRF VPN1, enter the following command at the OSPF Config level.
Brocade(config)# router ospf vrf VPN1
