Filtering Routes Between EIGRP Neighbors

A.

The method used to filter routes between EIGRP neighbors within the same autonomous system is distribute-list.

Distribute-list is a feature of EIGRP that allows for filtering of routes based on access-lists. Access-lists define what routes should be allowed or denied, and distribute-list applies these access-lists to EIGRP routes to either permit or deny them from being advertised to or received from neighboring routers.

In the context of filtering routes between EIGRP neighbors within the same autonomous system, distribute-list can be used to prevent certain routes from being advertised or received by specific routers in the network. This can help to control the flow of traffic and prevent loops or other network issues.

Policy-based routing is a different feature that allows for routing decisions based on policies or criteria beyond the traditional routing table, such as source IP address or packet type. It is not directly related to filtering EIGRP routes between neighbors in the same AS.

Leak-map is a feature of OSPF that allows for redistribution of external routes into OSPF while still maintaining control over which routes are redistributed. It is not directly related to EIGRP.

Route tagging is a way to mark or label routes with additional information, such as a priority or preference value. It can be used to influence routing decisions, but it is not a method for filtering EIGRP routes between neighbors in the same AS.
