Cisco CCNP / BSCI Test Tutorial: The Passive Interface Command And OSPF
To go the BSCI Test and turn into a CCNP, You should know about the proper use of passive interfaces. You figured out about passive interfaces with your CCNA scientific tests, but right here properly evaluation the basic principle and clear up one false impression relating to passive interfaces and OSPF.
Configuring an interface as passive will continue to enable the interface to get routing updates, nevertheless the interface will not transmit them. While the command by itself would make you think that this command will likely be used in the interface stage, that isn't the situation. Beneath, nicely configure ethernet0 being a RIP passive interface.
Ethernet0 will no https://en.search.wordpress.com/?src=organic&q=라이브스코어 more ship RIP routing updates, but will acknowledge them.
The passive interface notion is obvious enough with RIP, IGRP, and EIGRP all protocols that send out routing update packets. But OSPF doesnt mail routing update packets OSPF sends hyperlink point out ads. Its the inability from the passive interface command to prevent LSAs that guide quite a few to imagine that passive interfaces can not be utilized with OSPF.
Although OSPF will not sent “routing updates” in the shape that RIP, IGRP, and EIGRP do, you can however configure an OSPF-enabled interface as 해외스포츠중계 passive in an effort to reduce OSPF site visitors from exiting or entering that interface. No OSPF adjacency is often fashioned if one of the interfaces involved is usually a passive interface, and if you configure an OSPF-enabled interface as passive the place an adjacency now exists, the adjacency will fall presently.
Permit’s see that in motion. R1 and R2 have an current OSPF adjacency more than their Ethernet interfaces. In an effort to reduce routing site visitors, R1’s e0 interface is configured as passive. The adjacency drops immediately.
R1(config)#router ospf 1
18:31:eleven: %OSPF-five-ADJCHG: Course of action 1, Nbr two.2.2.two on Ethernet0 from Entire to DOWN, Neighbor Down: Interface down or detached
Figuring out tips on how to use the passive interface command is an important Element of getting a CCNP, and of remaining a grasp networker. Good luck for you in both of these pursuits!
