Eigrp routes not updating

eigrp routes not updating-48

This does not mean that a link that is not a successor or a feasible successor cannot be used to reach a remote subnet; if the successor and feasible successor are unavailable, it can still be used - however, DUAL must again perform calculations to find the best route.The topology we’ll work with here is included below: We’ll be working from the perspective of R0.

A word containing document to a Wireshark capture screenshots, is attached.This is the main reason for fast convergence time (distance vector uses hold time, split horizon, etc, while link state does not).Scaling OSPF: If network has many routers (~50 or more, a few hundred subnets), would result in:* Slow convergence time* Memory shortages/processor overloading Scalability Solutions Include:* OSPF Areas: Break up the network so that routers in one area know less topology information about the subnets in the other area, and don’t know about other routers at all.* Border Router: OSPF Area Border Router (ABR), border between 2 different areas (sits in both areas).* Makes other routers in same area view network as if it had fewer routers.* Area 0 defined as backbone, OSPF designs hierarchical** Note: doesn’t change of subnets know, just decrease of bytes/require memory to process updates **Successors are in topology table, and are the best route (the route with lowest metric, which is also in routing table). Each router discovers its neighbors on each interface, list kept in neighbors table.2.Each router uses a reliable protocol to exchange topology information in its topology database.3.Each router finally places the best route to each subnet in the IP routing table.

Loop Avoidance: Link state does not use SPF algorithm, but rather it relies on router broadcasting downed link immediately.

Please, take a look at them and offer your thought. Ps1: I would say that you are testing EIGRP on 15.2 free, as the project is most likely covers the latest version.

PS2: If you repeat the test with 15.2 version, please attach file OCAP and your questions.

Here area 0 Shows the routers ospf neighbors Remember that the RID is that router’s highest IP address on a physical interface when OSPF starts running.

Alternatively, if a loopback interface has been configured, OSPF uses the highest IP address on a loopback interface for the RID, even if that IP address is lower than some physical interface’s IP address.

Feasible Successors are in topology table, and are placed when the neighbor has a lower metric for its route.
