Which routing instance type is used to facilitate filter based forwarding?
Forwarding. This instance type is used for Filter Based Forwarding (FBF). If you’re not familiar with FBF, it is the same thing as Policy Based Routing (PBR) on a Cisco device.

What is filtering forwarding?
Filter-based forwarding enables you to configure packet filters that classify packets based on header information, such as IP source address, IP destination address, IP protocol field, and source and destination TCP/UDP port numbers.
What is routing instance in 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. Each routing instance has a unique name and a corresponding IP unicast table.
What are firewall filters?
Firewall filters are the Junos version of an ACL. They are used to match traffic and apply an action. This can be for security (allow or deny traffic), but it can also be for a policy (such as a routing or CoS policy). Generally, firewall filters are stateless.
How do I check the VRF route in Juniper?
show route export vrf-target
- Syntax. content_copy zoom_out_map.
- Description. Display the VPN routing and forwarding (VRF) target communities for which policy-based route export is currently distributing routes.
- Options. none.
- Required Privilege Level. view.
Which source of routing information is preferred by default Juniper?
You can modify the default preference values for any of the routing information sources. C. By default, a static route is more preferred than a RIP route.
What are three types of routing instances choose three?
Multiple instances of BGP, OSPF, and RIP are used for Layer 3 VPN implementation. The multiple instances of BGP, OSPF, and RIP keep routing information for different VPNs separate.
What is VRF in Juniper?
Use virtual routing and forwarding (VRF) to divide an EX Series switch into multiple virtual routing instances. VRF allows you to isolate traffic traversing the network without using multiple devices to segment your network. VRF is supported on all Layer 3 interfaces.
What are the 3 types of firewalls?
According to their structure, there are three types of firewalls – software firewalls, hardware firewalls, or both.
What are the two main types of filters firewalls use to filter traffic?
Basic firewalls provide protection from untrusted traffic while still allowing trusted traffic to pass through. Packet filters, proxy filters, and stateful packet filters are some of the technologies used to accomplish this protection.
How do I check my VRF details?
To verify all configured VRFs in summary mode, enter the show vrf command, as in the following example. To verify a specific VRF in detail mode, enter the show vrf detail vrf-name command, as in the following example.
What is VRF Juniper?
Which route is preferred OSPF or BGP?
BGP and OSPF are two of the most common routing protocols. While BGP excels with dynamic routing for large networks, OSPF offers more efficient path choice and convergence speed.
Which type of routing is preferred?
Route 2 is preferred because it has a higher LocalPref value and a lower Preference2 value. You can also mark route preferences with additional route tiebreaker information by specifying a color and a tiebreaker color (by including the color and the tiebreaker color2 statements in the configuration).
What are 4 types of static routes?
The following types of IPv4 and IPv6 static routes will be discussed:
- Standard static route.
- Default static route.
- Summary static route.
- Floating static route.
What are the 4 types of routers?
They are wired routers, wireless routers, core routers, edge routers and VPN routers.
What is the difference between VRF and virtual router?
Virtual routing and forwarding (VRF) is a technology-based on the operating principle of a physical router. Unlike a single router, virtual routers (VR) can be run simultaneously as multiple instances. Each of these instances uses its own routing and forwarding table.
What are the 4 major types of firewalls?
Five types of firewall include the following:
- packet filtering firewall.
- circuit-level gateway.
- application-level gateway (aka proxy firewall)
- stateful inspection firewall.
- next-generation firewall (NGFW)
Which firewall is best?
Bitdefender Total Security. Best for all round security with firewall protection.
How do I check my VRF routing table in Juniper?
show route table
- Syntax. content_copy zoom_out_map.
- Syntax (EX Series Switches, QFX Series Switches) content_copy zoom_out_map.
- Description. Display the route entries in a particular routing table.
- Options. brief | detail | extensive | terse.
- Required Privilege Level. view.
What OSI layer is BGP?
BGP in networking is based on TCP/IP. It operates on the OSI Transport Layer (Layer 4) to control the Network Layer (Layer 3).
Is BGP faster than OSPF?
OSPF has faster convergence times than BGP. Network convergence is the speed at which a router can adjust the path used to a destination network if a network outage occurs.
Which is faster static or dynamic routes?
Static Routing requires less bandwidth than dynamic routing, where dynamic routing requires large bandwidth. In static routing routes, the path is updated by the user or an administrator, while in dynamic routing, routes are updated automatically.
Which is faster static routes or dynamic routes?
Static routing uses small routing tables with only one entry for each destination. It also requires less computation time than dynamic routing because each route is preconfigured.
Which three 3 are types of routes found in a routing table?
There are 3 types of routing:
- Static routing – Static routing is a process in which we have to manually add routes to the routing table.
- Default Routing – This is the method where the router is configured to send all packets towards a single router (next hop).
- Dynamic Routing –
