This is the behavior we would expect, because E1 routes must always be preferred over E2 routes. The result on R1 is that the route via R4 is less preferred, since it now has a metric of and still a forward metric of 2 vs the metric of 20 and the forward metric of 2 via R5.
This is the path selection that we would ideally want, because the total cost of the path via R4 is metric of plus a forward metric of 2 , while the cost of the path via R5 is 22 metric of 20 plus a forward metric of 2. The result of this path selection would be the same if we were to change both routes to E1, as seen below.
R5 config t Enter configuration commands, one per line. R5 config router ospf 1 R5 config-router redistribute eigrp 10 subnets metric-type 1 R5 config-router end R5. So now this begs the question, why does it matter if we use E1 vs E2? R5 config router ospf 1 R5 config-router redistribute eigrp 10 subnets metric-type 1 metric R5 config-router end R5. Next, Path 2 is available via the link to R3 with a cost of 1, plus the link to R5 with a cost of 1, plus the redistributed metric of , masking this total path a cost of as well.
The result is that R1 installs both paths equally:. R5 config router ospf 1 R5 config-router redistribute eigrp 10 subnets metric-type 2 metric R5 config-router end R5. Even though the end-to-end costs are still the same, R1 should now prefer the path with the lower redistributed metric via R The forward metric of this route means that the total cost is still the metric of 99 plus the forward metric of In this case, even though both paths are technically equal, only the path with the lower redistribution metric is installed.
R5 config router ospf 1 R5 config-router redistribute eigrp 10 subnets metric-type 2 metric 1 R5 config-router end R5. This is the result we may not expect. Only the path via R5 is installed, not the path via R4. First, as we saw above, R1 finds both routes to the prefix with a metric of 1.

What is scope of CCIE? How to remember 7 layers of OSI Model? N1 and N2 both have an external cost of x. The only difference is that N1 is redistributed into OSPF with a metric-type 1 and N2 is redistributed with a metric-type 2. The internal cost along the way is not considered.
On the other hand, the cost to reach N1 is incremented by the internal cost. Type 1 routes are preferred over type 2 routes in case two same cost routes exist to the destination. The default is type 2. We will have many comp How to gather packet captures in pcap format on a router? There are various ways to capture the packets on Cisco router here let see how we configure and then capture the packets required in pcap f Difference between Underlay and Overlay Networks.
Today I am going to talk about the underlay and overlay networks and protocol used for these purposes. Most of the software defined netwo
