Metric calculation of EIGRP:

This value is mismathed with EIGRP calculated metric(i.e 2297856). Please someone figerout if some thing I have missed during calculation.

HI Sanjib,
Metric = 256*[10^7/BW(min)] + [sum of delay]/10
Metric = 256*[10^7/1544] + (20000+5000)/10]
Metric = 256*[6476+2500]
Metric = 2297856
We see the minumum bandwidth to reach the destination is 1544Kbps
Default delay on the link to reach the destination (serial link) is 20000 microseconds.
Default delay of the loopback interface is 5000 microseconds.

ISIS Redistribution

I'm having a couple problems with mutual redistribution between ISIS and EIGRP.
A little setup, I was trying to redistribute only level-1 routes into EIGRP and it would redistribute both L1 and L2 routes. I know that I have both L1 and L2 routes in the routing table on the redistribution router. The configuration I've been using is:
router eigrp 1
redistribute isis level-1 metric 100 100 200 1 1500

The following output shows an IS-IS router redistributing static, RIP, IGRP, EIGRP, and OSPF routes.
router isis
network
redistribute static
redistribute rip metric 20
redistribute igrp 1 metric 20
redistribute eigrp 1 metric 20
redistribute ospf 1 metric 20The IS-IS metric must be between 1 and 63. There is no default-metric option in IS-IS?you should define a metric for each protocol, as shown in the example above. If no metric is specified for the routes being redistributed into IS-IS, a metric value of 0 is used by default.

Route Redistribution between RIP and OSPF

Hi all,
I'm building my home lab and having difficutly to get this part of router redistribution work.
I can't ping from PC, Server and SW1 to R2's int f0/0, f0/1 and SW2's G0/1.
I can't ping from R1 to R2's f0/1, SW2
Vice versa, I can't ping from SW2 to R2's f0/0, R1's f0/0 & f0/1, SW1, PC and Server.
Also, I can't ping from R2 to R1's f0/1, SW1, Server and PC.
I think the reason cause these ping's failure is I didn't config the Route Redistribution between RIP and OSPF(on R2)correctly. I strugled for hours to change comand around but still can't figure it out. I attached my Topology and config. file to you and please help!

Hi,
On R1, you should not be advertising 10.0.0.0/24 via OSPF => redistribution will handle that
On R1, you should not be advertising 20.0.0.0/24 via EIGRP => redistribution will handle that
On R2, you should not be advertising 30.0.0.0/24 via OSPF => redistribution will handle that
On R2, you should not be advertising 20.0.0.0/24 via RIP=> redistribution will handle that
On R2, under your rip process, you should put a metric to RIP otherwise it would redistributed with infinite metric (i.e. 16). Btw, you did put a seed metric on your EIGRP redistribution which is fine.
Also if you're talking RIP with switch2 and would like to send rip updates to him, you remove your passive interface statement
your rip statement should be somethin like that :
router rip
version 2
redistribute ospf 1 metric 5
passive-interface FastEthernet0/0
network 30.0.0.0
no auto-summary

DataCenter to DataCenter with no OTV

Hello everyone, We are currently running a datacenter with 2 7K switches and re route to our existing DR site which is a different network. We are building a new data center close by and will have 2 10 Gig links <1 MS latency. I have heard that OTV may not be the best investment, even though it is easy and separates things like Spanning tree, and your hsrp gateways.
So due to cost, we will connect 2 7K's but we will not use OTV, this will be a VPC trunk to both 7K's. We use HSRP and know how to change this and change spanning tree elections, my question here is should I switch to GLBP, then elect spanning tree based on load? also we use EIGRP to route from the 7K cores with 10.0.0.0, should modify metrics or will eigrp work by default?

The vpc peer link *is* a trunked port-channel, however it has special rules for loop prevention. Specifically, if a packet arrives over the peer link and is destined for a vpc member port, that packet will dropped if all ports in the vpc port group are up. So ideally you are never sending traffic across the peer link unless there is a link failure in a vpc.
In addition to the original doc I mentioned, this is a good one to understand supported topologies.
http://bradhedlund.com/2010/12/16/routing-over-nexus-7000-vpc-peer-link-yes-and-no/
If the 3750 switches are connected with a vpc, then what you mention is not supported. If they are connected with individual layer 3 links, then this would be supported. If they are connected with two seperate trunk links, then it would be supported so long as you have a dedicated, non-vpc, spanning-tree link between 7k's.
You can peer betwen 7k's over the vpc peer link, but it is the least recommended practice. Most recommended is a dedicated layer 3 point to point link, or a non vpc trunk or port-channel with peering over vlan svi's.

Metrics when redistributing a static default route into EIGRP?

I saw a network working with EIGRP and resdistributing a static default route into it. I did not find the "default metrics" to redistribute into EIGRP but the static default route works and is redistributed. My understanding was that everytime you redistribute into EIGRP you needed to specify the metrics. How come this network is working? Can someone explain or point to a cisco document what explains it?
Sample of the config:
router eigrp 1
redistribute static
no autosummary
network Y.Y.Y.Y
ip route 0.0.0.0 0.0.0.0 X.X.X.X
Thank you,

It's just one of those specific things about EIGRP and IOS, maybe a design choice. If they do use the interface as the seed metric then that would help explain why it's that way.
Weirdly if you are using EIGRP VRF address family configuration on IOS and you redistribute statics you do need a metric.
And I believe NXOS running on Nexus switches also needs a metric defined.
Just one of those things you have to remember but it would be good if it was consistent.

Offset-list to change EIGRP Metrics

I've got a sup720 that I would like to control which routes in the eigrp topology database get injected into the routing table. There are about 20 entries in the topology database for a specific route all with the same composite metric.
Any suggestions on how to control which routes populate the routing table?
Will using the offset-list command and a acl do it? If you guys think that will work could you give me an example of what the acl would look like?
My network is running just one eigrp process, with no route distribution.
Thanks in advance!

Craig
What you are asking for can be done but it will be a bit tedious. You describe having 20 entries in the topology table and you want to control which one gets placed into the routing table. To do that you can either make the composite metric of the one entry more attractive or you can make the composite metric of the other 19 less attractive.
When you use an offset list you add to the metric of an entry. It will not make any entry be more attractive but it can make other entries less attractive. So you could configure an offset list identifying the route in question and apply some offset (100 should work for example). Then you would need to apply this offset to the 19 neighbors who are advertising the route.

EIGRP Metric and UCLB Doc

Team,
http://www.cisco.com/c/en/us/support/docs/ip/enhanced-interior-gateway-routing-protocol-eigrp/13677-19.html
I somehow find the doc for EIGRP unequal cost load balancing a little bit misleading because it shows that the cost to reach network X is additive to demonstrate EIGRP variance. The only time that the cost will be additive is if only delay is used along the path to network X. However, there is no mention about delay solely being used as the metric in the doc which might lead one to think that the metric for a certain route is FD = cost to neighbor + neighbor's RD.
Thoughts please. Thanks.

EIGRP Wide-metric support

It appears EIGRP only sends the classic-scale-metrics while operating in non-named configuration mode (E.G. router eigrp # ) AND Always sends the wide-metric format while operating in Named Configuration mode (E.G. router eigrp ROCKS) regardless of the 15.2 IOS version.
When my router is running in Named config mode, sh eigrp protocols reveals K6=0,
when I remove the Named config and use the legacy router eigrp # config mode, the same sh eigrp protocols does not list the K6=0 value (only K1 - K5).
The reason I ask is the Cisco white paper (EIGRP Wide Metrics) dated Nov 2012, states if a legacy EIGRP peer is interfacing with a new EIGRP peer, the new EIGRP peer will send both formats. - Is this doc outdated by a newer doc?
Thanks
Frank

Update- The original title should be referred to as EIGRP Virtual-Instance (that does support the legacy 32-bit metric and just might also support the 64-bit wide metrics; depending on your configuration).
Viewing the show command (Show command 1) based on EXAMPLE CONFIG 1 below, it's clear the K6 value is not used; only the K1 - K5 values.
If address-family vrf was implemented, as shown in EXAMPLE 2, it's clear the new wide-metric is in effect.
The question still remains, how does an EIGRP peer configured to recognize link speeds greater than 10Gbps interact with EIGRP peers that are not operating in 64-bit mode? What do the configurations look like for each of the peers?
ANYONE know?
Thanks
Frank

MTU in EIGRP metric?

Hello everyone,
Many pages describing EIGRP say that one of used metrics is the interface MTU. However, the formula for calculating the composite metric does not take MTU into account so the MTU can not affect the composite metric of a route.
I would like to ask how exactly is the MTU used in the EIGRP, then. Thank your for any insights!
With best regards,
Peter

Peter
You ask a very good question and I believe that you are on the right track in trying to understand it. Your observation is correct that MTU is a required parameter in specifying EIGRP metric (for redistribution) and is one of the parameters that is advertised. You are also correct in observing that there is nothing in the EIGRP calculation that uses MTU. So the real answer is that the EIGRP specification included MTU but that it does not play any active role in the path selection done by EIGRP.

Why EIGRP metric didn't change after add delay?

Here is the lay out:
--R2--
E1---R1---E2/ \E3
--R3--
I have added delay for R2's E2 interface, but when I check the EIGRP topology from R1 for E3, the metric didn't change and they are still the same for R2 and R3.
Do I miss anything?

You've discovered that ascii diargams don't work on the forum. :-)
Remember that EIGRP always takes its metric from the inbound interface. In this case, R2 and R3 take their "connected metric" to E3, and advertise it to R1. R1 takes its delay from E2, and adds it to the delay R2 and R3 advertised. R2's metrics on E2 have no bearing or impact on R1's metric for E3.
R2's metric on E2 will have an impact on R2's cost to reach E1, however.... Always consider the direction the update is going, and then add cost on the inbound side of one of the hops if you want to traffic engineer, rather than the outbound side.

Database size and Storage Metrics are mismatching

Hi,
When I look at the storage metrics for one of our SharePoint Web Application root site collection it shows the top sized site as 28.2% of parent and the size as 21178.5 MB. When we calculate the total size of the site collection from
that it should 74994 MB. But when I see the size of the content database ( this is the only site collection in this content database) it shows 185661.5 MB as the size and 26852.5 MB as the space available. When I run the report (Disk Usage By Top Tables)
on that database it brings the list with dbo.AllDocStreams table at the top (Data - 80333 MB) followed by dbo.AuditData (Data - 48305 MB) followed by dbo.AllUserData (Data - 8593 MB).
3 years back we migrated this SharePoint Web Application from 2007 to 2010.
I saw that the recycle bin has only 30 day worth data.
How can we reduce the size of the database according to what it shows in the storage metrics? Appreciate any help.
Thanks.
rani

so... your database has:
80gb in files (includes version history)
50gb in audit data
8.5gb of list data
plus ~27gb of free space for growth between backups
total of ~165gb (which is close enough to the 185661.5 that you listed)
you need to split up the site collection, and then spread the site collections across multiple databases.

Having an issue adding network to eigrp

I'm doing a class project using a network simulator and am asked to: Design and implement an network for company RoutersCourseMatters. The names of the department names at this company are Faculty, Staff, and Students. For security reasons, each department must be isolated from each other's broadcast domain on the network. The Faculty have 50 end devices that need to be connected to the network. Staff has 26 end devices and the Students have 100 end devices. The network spaced provided by the ISP is 192.168.0.0/24. The dynamic protocol used for this network must be for Cisco-only equipment. Test each department network with just one end device and ensure full connectivity across the entire network
So we have our network topology setup for the class project(see picture attached). We are using one router for faculty+staff. Faculty has ip/mask of 192.168.0.1/26 and staff is: 192.168.0.65/27. we have a seperate router for students which the IP subnet for students is 192.168.0.150/25. The routers are directly connected and are using ips 192.168.0.98/29 & 192.168.0.100/29 so since the two routers are directly connected on the same subnet they have no issue pinging each other. The problem is pinging hosts from a subnet to hosts on a different subnet. When I try and add ANY 192.168.0.* subnet to eigrp it instead adds 192.168.16.* network. For instance on the faculty/student router if i do a 'router eigrp 1' command followed by 'network 192.168.0.0 0.0.0.63' it shows network 192.168.16.0 has been added to eigrp under show run. here is show run command:

Hello lolwar,
From your setup and description you provided I see some mismatch in IP subneting you calculated.
For instance in your diagram you have networks 192.168.0.0/26 (FACULTY), 192.168.0.64/27 (STAFF), 192.168.0.96/29 (point-to-point link between routers) and 192.168.0.128/25 (STUDENTS).
First, you're wasting IP addresses, because you have unused space between point-to-point link and STUDENTS subnet. It's a good practice, when calculating subnets first calculate the biggest, subnet, then smaller one until the smallest one (usually some point-to-point cross-connects). For more about this see this guide.
Now, the issue I see as the most important is, that you have in your diagram networks as I mentioned above, but into your EIGRP process you're adding completely different subnets (192.168.16.x, 192.168.20.x,...).
I entered following:
STUDENT ROUTER =------------>
router eigrp 1
network 192.168.0.96 0.0.0.7
network 192.168.0.128 0.0.0.127
FACULTY/STAFF ROUTER =------------->
router eigrp 1
network 192.168.0.0 0.0.0.63
network 192.168.0.64 0.0.0.31
network 192.168.0.96 0.0.0.7
And all works just fine, computer's are able to ping each other. Also although it's not necessary, it's good to includes network wildcard mask into the "network" command under EIGRP (or OSPF) configuration.
I hope this will help you (please rate if this is the case. Thanks.)

How do you Redistribution EIGRP into OSPF and maintain a distance of 250 for a static route?

Ok, I have scoured the forums long enough and have to post. The design is below. I moved a firewall to our new data center, which required adding some static routes for VPN connections and broadband backups. To minimize the amount of static routes I redistribute static into EIGRP with a route-map and prefix-list.
My problem is the next part of my network. When the data leaves my 56128's it hits an edge device connecting to our dark fiber. On this edge device I am running OSPF onto the dark fiber, then redistribute some EIGRP subnets into OSPF and again all is well.
Everything works up until the point the redistributed routes hit my RIB at my main data center where I am running IBGP. IBPG is run between our MPLS router and core for all our remote sites. When my backup route from the 56128's hits the cores, it supersedes the BGP route because the AD route O E2 [110/20] is lower than the BGP AD B [200/0]. Given the configuration below what can be done to remedy this? Oh when I redistribute I can only change the AD for the backup routes, all other routes should stay the same.
56128's where my static routes are:
ip route 192.168.101.0/24 192.168.30.77 name firewall 250
router eigrp 65100
redistribute static route-map Static-To-Eigrp
route-map Static-To-Eigrp permit 10
match ip address prefix-list Static2Eigrp
ip prefix-list Static2Eigrp seq 2 permit 192.168.101.0/24
Edge device:
router eigrp 65100

ip prefix-list EIGRP_INTO_OSPF seq 10 permit 192.168.94.0/29 le 32
ip prefix-list EIGRP_INTO_OSPF seq 15 permit 192.168.26.32/29 le 32
ip prefix-list EIGRP_INTO_OSPF seq 20 permit 192.168.30.72/29 le 32
ip prefix-list EIGRP_INTO_OSPF seq 25 permit 192.168.20.128/25 le 32
ip prefix-list EIGRP_INTO_OSPF seq 26 permit 192.168.101.0/24 le 32 <- Backup Route for MPLS Remote Office
route-map EIGRP_INTO_OSPF permit 10
match ip address prefix-list EIGRP_INTO_OSPF

So in the case of a /24. If it were say broken up into /25's? From our remote sites we are using aggregate-address summary-only. Not sure how I would advertise a more specific route via BGP, sorry.
I didnt have this problem until I moved my firewalls. They plugged into the cores where IBGP was running and the static never kicked in unless the bgp route disappeared. I guess I could use my static redistribution for my VPN sites and use statics across the cores for the handful of backup links I have.

Eigrp varience

when adding the varience command on eigrp, do you just add it after the network you have added or does it just basically double etc the metric of the fastest link ?

Carl,
You just need to add it after the network command. You can also use the command "traffic-share balanced" for intelligent load-sharing between the links...
The following URL explains in detail as to how the router uses the variance command:

Hope this helps.. all the best.. rate replies if found useful...

Unequal Load Balancing with EIGRP over 4 Wireless networks

We are trying to load-balance on 4 interfaces that have unequal bandwidths. The setup looks like this
8 Computers -> Empty Config Switch -> 3560 Router\Switch -> 4x Wireless Radios on different frequencies - networks -> 3560 Router\Switch->Empty Config Switch -> 8 Computers
We have EIGRP setup and the bandwidths defined, and the routes are showing proper share counts, but once we start adding traffic to the network, they all jump on one of the links. The config and everything looks right, its just not working. I have tried switching to different cef algorithms. Removed the vlans . I made them equal cost and they did the same thing. Its like EIGRP does not want to load balance.
When i did this config with static routes or as OSPF, it actually load balanced them, but I'm stuck with a 1:1 share ratio. If i could control the ratio, then that would be an acceptable solution.
Any ideas on what could be causing this?

Yup, that was the first cef algorithm I had tried.   ip cef load-sharing algorithm include-ports source destination
I tried all of the different types.
Also, I was sending data trough iperf from 4 computers + 1 comp steaming video on one network to 5 computers on another network. In any case of source or destination, it should have switched over. The odds of it all going on Vlan 5 is ~ 0.6%   Restarting the router sometimes places it all on a different vlan, but in any case its all or nothing.
