What IS OSPF traffic engineering?
OSPF Support for Traffic Engineering. Traffic engineering allows you to control the path that data packets follow, bypassing the standard routing model, which uses routing tables. When traffic engineering is enabled on the routing device, you can enable OSPF traffic engineering support.
What is MPLS TE tunnel?
MPLS TE builds unidirectional tunnels from a source to the destination in the form of LSPs, which is then used for forwarding traffic. The point where the tunnel begins is called tunnel headend or tunnel source, and the node where the tunnel ends is called tunnel tailend or tunnel destination.
What is RSVP TE protocol?
RSVP-TE is used to establish MPLS transport LSPs when there are traffic engineering requirements. It is mainly used to provide QoS and load balancing across the network core, and includes the ability to control all-optical networks.
What is network TE?
TE is the process of steering traffic across to the backbone to facilitate efficient use of available bandwidth between a pair of routers. Prior to MPLS TE, traffic engineering was performed either by IP or by ATM, depending on the protocol in use between two edge routers in a network.
Which type of work is under the city traffic engineer?
Typical traffic engineering projects involve designing traffic control device installations and modifications, including traffic signals, signs, and pavement markings. Examples of Engineering Plans include pole engineering analysis and Storm Water Prevention Programs (SWPP).
What is OSPF area?
An OSPF network can be divided into sub-domains called areas. An area is a logical collection of OSPF networks, routers, and links that have the same area identification. The router does not have detailed information about network topology outside of its area, which thereby reduces the size of its database.
When to enable OSPF support for traffic engineering?
When traffic engineering is enabled on the routing device, you can enable OSPF traffic engineering support.
Which is the IP address for OSPF 2?
Current configuration: hostname r3.3.3.3 interface Loopback0 ip address 3.3.3.3 255.0.0.0 interface ATM2/0.20 point-to-point ip address 200.0.0.3 255.255.255.0 router ospf 2 network 200.0.0.0 0.255.255.255 area 1 end This section provides information you can use to confirm your configuration is working properly.
When to use protocol preference in traffic engineering?
In Junos OS Release 9.4 and later, you can configure OSPF to take protocol preference into account to determine the traffic engineering database credibility value. When protocol preference is used to determine the credibility value, IS-IS routes are not automatically preferred by the traffic engineering database, depending on your configuration.
How does RSVP support for traffic engineering work?
The Constrained Shortest Path First (CSPF) algorithm uses the traffic engineering database to compute the paths that MPLS LSPs take. RSVP uses this path information to set up LSPs and to reserve bandwidth for them. By default, traffic engineering support is disabled.
