  2. Log in as the “root” user. There is no password.
  3. Start the CLI.
  4. Enter configuration mode.

  6. Create a management console user account.
  7. Set the user account class to super-user.
  8. Configure the router’s domain name.

What is routing instance Juniper?

A routing instance is a collection of routing tables, interfaces, and routing protocol parameters. The set of interfaces belongs to the routing tables, and the routing protocol parameters control the information in the routing tables.

What is dynamic routing example?

Example of dynamic routing protocols are BGP, EIGRP, OSPF and RIP that you can choose according to your topology, specific requirements ( like scenario: WAN, Internet Edge, Data Center, SP networks), technical capabilities (vendor, type of devices, supported protocols) and so on.

How do I set a default route in Juniper?

Solution

  1. Connect to the firewall either by console cable or via SSH, go to CLI mode then configuration mode. login: PeteL Password: ************ — JUNOS 12.1X47-D10.4 built 2014-08-14 22:21:50 UTC.
  2. Here is the syntax for adding a route, (0.0. 0.0/0 denotes the default route or GOLR).
  3. Save the changes.

How do I find my juniper configuration?

To display the current configuration for a Juniper Networks device, use the show command in configuration mode. This command displays the configuration at the current hierarchy level or at the specified level.

How do I check the last configuration change in Juniper?

To configure this type of logging, follow these steps:

  1. In configuration mode, go to the following hierarchy level: [edit]
  2. Configure the log file: [edit system syslog]
  3. Configure the change-log facility and severity level: [edit system syslog filename ]
  4. Verify the configuration:
  5. Commit the configuration:

How do I show VRF on Juniper?

show ip vrf

  1. Syntax. show ip vrf [ [ detail ] [ vrfName ] | interfaces [ detail ] ] [ filter ]
  2. Release Information. Command introduced before JunosE Release 7.1.
  3. Description.
  4. Options.
  5. Mode.

What is Virtual Router in Juniper?

In Junos Software, a virtual router is a type of routing instance, which is a collection of routing tables, interfaces, and routing option settings. To establish a virtual router, you do the following: Create a virtual router. Assign an interface to a virtual router (if not inet.

What are the three types of dynamic routing protocols?

Types of Dynamic Routing

  • Open Shortest Path First (OSPF)
  • Enhanced Interior Gateway Routing Protocol (EIGRP)
  • Intermediate System to Intermediate System (IS-IS)
  • Routing Information Protocol (RIP)

How are routing instances used on a Juniper router?

On a Juniper switch or router, we can create additional virtual routing tables, called routing-instances. These are similar to a VRF on a Cisco Router. Each routing instance groups routing tables (remember different tables are used for different families), interfaces, and protocol configuration into a single place.

When do static routes get activated in Juniper?

Static routes are activated when the specified next hop is reachable. You can specify options that define additional information about static IPv6 routes. These attributes, for example a community tag or route metric, are included with the route when it’s installed in the routing table.

What is the route 10.0.4.8 / 30 in Juniper Networks?

The route 10.0.4.8/30 is the link between the New University router and the customer network routers, and it is available in the routing tables of both virtual routers. This is important to maintain reachability for Internet traffic (BGP requires valid next-hops for a route to be active and advertised).

Can a Junos instance create a routing table?

This routing instance creates a separate routing table, but it does not create a separate forwarding table. Remember that JunOS has a very clear definition between routing (control plane) and forwarding (forwarding plane). The result is that routes may be learned from various sources, and installed in the instance’s routing table.
