To configure a routing instance for OSPFv3, you must include at least the following statements in the configuration: routing-instance-name { interface interface-name; instance-type (no-forwarding | virtual-router | vrf); vrf-import [ policy-names ]; vrf-export [ policy-names ]; protocols { ospf3 { ... ospf3-configuration ...

In Junos OS Release 9.2 and later, you can configure OSPFv3 to support address families other than unicast IPv6. This example shows how to configure an OSPF interface on a broadcast or point-to-point network. Before you begin: Configure the router identifiers for the devices in your OSPF network. See Example: Configuring an OSPF Router Identifier.

Oct 10, 2010 · In Junos OS, there is not much direct interaction between the routing protocols. Instead, there are central gathering points where all protocols install their routing information. These are the main unicast routing tables inet.0 and inet6.0.

I am currently learning the redistributing static routes into OSPF, a couple of questions due to the confusions: Topology: RouterA. ----- (interface1) RouterB (interface2: ospf-enabled) ----- (Rest of OSPF routers) Config: "set protocols ospf export STATIC-ROUTES"

To introduce routes that are not native OSPF routes, like statics, BGP or RIP, you will need to configure an export policy that matches the routes you want to "redistribute". You do not need to configure RIB groups to "redistribute" routes.

In the import statement, you list the name of the routing policy used to filter OSPF external routes from being installed into the routing tables of OSPF neighbors. You can filter the routes, but not link-state address (LSA) flooding.

Jul 5, 2021 · This article demonstrates how to configure a generated route and inject that default route in OSPF from R2 to R3 based on the presence of 172.16.0.0/32 in the BGP routing table in R2. Also, if in case we lose that route we want to flush …

Jul 5, 2013 · I have a Junos router (Juniper SRX) with the default route pointing to the ISP (IP and default route assigned by DHCP) and a pair of Cisco Nexus switches with OSPF routing between all the boxes. I needed to originate a default route from SRX to Nexus switches.

For an OSPF area, you can summarize and filter intra-area prefixes. All routes that match the specified area range are filtered at the area boundary, and the summary is advertised in their place.

To enable OSPF in JunOS we need to define the interfaces on which it will run and the area to which the interfaces will be attached. Here, we have configured OSPF area 0 (0.0.0.0) on interface ge-0/0/0.0 and ge-0/0/1.0 for router R1. Now, …
