Hey guys,
Because Enhanced Interior Gateway Routing Protocol (EIGRP) has replaced IGRP in all ways, IGRP is not covered except to say that, for legacy reasons, you may still see it on some routers. Three main tables, which are stored in memory, support the EIGRP routing protocol: Neighbor Table: Information about all adjacent routers running EIGRP are. EIGRP route summarization. EIGRP has the ability to create summary routes at arbitrary boundaries by using manual summarization. Manual summarization can be applied anywhere in EIGRP domain, on every router, on every interface. Summary route will exist in routing table as long as at least one more specific route will exist.
Wish you can help me know this idea. So consider a situation where you possess routers configured with EIGRP and have got 3 various routes major to the location LAN - these are the routés in the róuting table. The location host can be 10.1.103.101, with its gateway L5 getting 10.1.103.5. Subnet cover up for this LAN has not long been provided. But I guess we can suppose structured on the last octet'h address beliefs for both.101 and.5, that there are usually 3 pieces in typical - therefore, the initial 5 pieces are assigned for the subnet address. That gives us the value of the mask as 255.255.255.248, or /29.
R1 is certainly the resource web host's gateway, with pathways through either R2, L3, or R4. L5 is the destination host's gateway.
Route through R1-R4-R5:
10.1.102.0/23 90/2875412 via 10.1.14.4, Serial 1/1
Path through R1-R2-R5:
10.1.100.0/22 90/2767614 via 10.1.12.2, Serial 0/1
Path through L1-R3-R5:
10.1.64.0/18 90/2988684 via 10.1.13.3, Serial1/0

The question can be, which path will end up being selected out of thése 3 routes for packets crossing from resource to location web host.
I selected path R1-R2-R5, bécause it provides the lowest metric among thé 3 routes. But the right answer is usually route L1-R4-R5, because it will be the almost all 'specific' route with the longest prefix duration.
THE QUESTION IS: What is given preference by EIGRP? Thé LOWEST METRIC Path, or the MOST SPECIFIC Path?
What requires precedence?
