Question

How to prevent the transmission of routing updates through all router interfaces? A) Configure static routes

B) Implement route summarization
C) Use routing authentication
D) Apply route filtering

Answer 1

To prevent the transmission of routing updates through all router interfaces, you can apply route filtering. By configuring filters, you can specify which routes should be allowed or denied based on certain criteria such as source or destination IP addresses, subnet masks, or other parameters.

Step-by-step explanation:

To prevent the transmission of routing updates through all router interfaces, you can apply route filtering. Route filtering allows you to control how routing updates are propagated throughout the network. By configuring filters, you can specify which routes should be allowed or denied based on certain criteria such as source or destination IP addresses, subnet masks, or other parameters.

For example, you can create an access control list (ACL) that specifies which prefixes should be advertised or received from neighboring routers. This helps prevent the propagation of unnecessary or potentially harmful routes. By applying the ACL to the appropriate router interfaces, you can restrict the transmission of routing updates and improve network security and efficiency.
