Because of the significance of EIGRP investigating issues connected with this convention is a significant capacity for an organization manager. There are various orders that are significant during EIGRP investigating.
The most involved order for EIGRP investigating is the “show ip eigrp neighbors”, “show ip course”, and “show ip conventions”. The orders can likewise be utilized for EIGRP investigating for IPv6. The distinction while involving it for IPv6 is the utilization of “IPv6” rather than “IP”.
The initial step after the arrangement of the EIGRP is to test the availability to the remote organization. We can test the network by utilizing the ping order, on the off chance that the ping fizzles, check the neighbor adjacencies utilizing the “show ip eigrp neighbors” order. Neighbor nearness probably won’t be made for a very long time, including:
- The connection point between the gadgets is down.
- The befuddle independent framework numbers.
- Perhaps the connection points are not empowered for the EIGRP interaction.
- A connection point is designed as uninvolved.
- Misconfigured EIGRP confirmation
Befuddled K qualities
Assuming that two switches shaped EIGRP neighbor nearness, however an association issue continues, this is perhaps because of a steering issue and here and there this may because of an availability issue for EIGRP including:
- The organization isn’t publicized on far off switches.
- An inaccurately designed latent connection point
- Because of ACL, which is hindering the publicized remote organizations?
Programmed synopsis is causing conflicting directing in a dis-touching organization.
Assuming every one of the courses are in the steering table, however the way that traffic takes isn’t right, this is perhaps because of the connection point data transfer capacity values. Actually look at the connection point data transmission for the investigating of this issue.
Layer 3 Connectivity
For neighbor adjacencies the layer 3 availability is significant. Without layer 3 availability, the neighbor adjacencies are impractical. We can check the layer3 network utilizing the “show ip interface brief” order. We can confirm the status and convention of associating connection points utilizing this order.
The “ping” order likewise check the layer 3 network starting with one switch then onto the next, straightforwardly associated switch, this order additionally affirm IPv4 availability between the gadgets. Figure 1 delineates the “show ip interface brief” order yield for R1. R1 shows availability to R2, R3, and neighborhood organizations. The ping to this large number of organizations is fruitful.
In the event that the ping is fruitless, check the organization cabling and furthermore check that the points of interaction on associated gadgets are on a typical subnet. Also, we can involve a similar order for investigating EIGRP for IPv6. For investigating IPv6 we just utilize the “IPv6” rather than “IP” for instance ” show ipv6 interface brief”
EIGRP Parameters
The boundaries are essential investigating contemplations for an EIGRP organization. A similar independent framework number should be arranged for the EIGRP area. We can begin the EIGRP cycle utilizing the “switch eigrp <as-number> order. The worth of the <as-number> contention should be something similar in all switches that are in the EIGRP directing area. The scope of this worth is from 1 to 65535.
We can confirm the as-number by utilizing the “show ip conventions” order on all switches. We can likewise check this by utilizing the “show running-config” order. Comparable orders can be utilized for investigating EIGRP for IPv6 with little distinction. The same orders are:
Router(config)# ipv6 switch <eigrpas-number>
Router# show ipv6 conventions
EIGRP Interfaces
The investment of connection points is likewise significant for the EIGRP organization. So we can check that all connection points are taking part in the EIGRP network recently arranged with the “network” order. The order can be applied to the classful organization address or a subnet with a special case cover.
Figure 2, shows the “show ip eigrp interfaces” order. It is delineated that the showed points of interaction are empowered for EIGRP. In the event that related connection points are not empowered for EIGRP, then, at that point, neighbors don’t frame a nearness.
Figure 3, outlines the result of the “show ip conventions yield. We can look at here the “Directing for Networks” area. The part shows the arranged organization for EIGRP.
In the event that the ideal organization isn’t there in this rundown, then, at that point, we can check the organization utilizing the “show running-config” order to ensure that the organization order was designed. Figure 4, outlines the result from this order to affirm the empowered points of interaction with the recorded addresses are empowered for EIGRP.
For EIGRP for IPv6 investigating, similar orders and standards are utilized. The equivalent orders are the accompanying:
Router# show ipv6 conventions
Router# show ipv6 eigrp interfaces
Detached Interface
Detached Interface can likewise mirror the erroneous courses on the grounds that the “inactive connection point” order stops both active and approaching directing updates, so the switch on that uninvolved point of interaction doesn’t become neighbors.
We can check any point of interaction on a switch is arranged as inactive utilizing the “show ip conventions” order. Figure 5 represents that R1’s GigabitEthernet 0/0 connection point is arranged as a uninvolved connection point since there are no neighbors switches on that connection.
The inactive connection points are likewise the necessity of safety. We can design the detached point of interaction is concealing for the EIGRP space. The organization chairman can arrange a detached connection point where he needs to dispose of neighbors contiguousness with different switches. Comparable orders and investigating measures can be utilized to EIGRP for IPv6. The same order is the accompanying:
Router# show ipv6 conventions
Router(config-rtr)# inactive point of interaction type number
Programmed synopsis
EIGRP programmed synopsis can likewise make an issue for network chairmen. The EIGRP for IPv4 naturally sums up the course at classful limits. On account of discontiguous networks, programmed synopsis can cause conflicting directing.
In Figure 6, the steering table of R2 doesn’t show the singular courses for the organization 172.16.0.0/24 and 172.17.0.0/24 subnets. Since Both R1 and R3 consequently summed up those subnets to the 172.16.0.0/classful limit prior to sending EIGRP update bundles to R2. In this manner the R2 has two equivalent expense courses to 172.16.0.0/16 in the steering table bringing about mistaken bundle directing. We can handicap programmed synopsis; involving the no auto-rundown order in switch EIGRP arrangement mode. There is no such thing as classful organizations in IPv6; so EIGRP for IPv6 doesn’t uphold programmed synopsis. All synopsis should be achieved utilizing EIGRP manual rundown courses.
