I have a test on eigrp next week and have been doing it in packet tracer so i`m ready but i can`t seem to get EIGRP to work!I have 3 routers and the loopback interfaces are configured because there`s not enough PCs to actually connect up to the kit. [code]
I have a issue in my network, i have 2 data connections with 2 different ISP (Principal & Backup connection). But with ISP "X" the RTO are stable (RTO 240), but with the ISP "Y" the RTO is in 5000 and the connection always are flapping.
I have recently connected a 10 Gig connection from the local telco between two sites on 6509's. These two sites also have a 1 Gig links between them. When I connected the 10 Gig link I expected the 10 gig link to be the preferred route, but after looking at the routes I noticed that both links have the same EIGRP path cost. Also the minimum BW for both links is 1000000Kb or 1Gb. Why?
We have 2x 3750G L3 switches and I am trying to set them up to use EIGRP but for some reason it’s not working, I created 2 routed ports on each switch and I want to route vlan10 traffic to vlan20 to S2. I also enable EIGRP as the routing protocol but I still cannot ping between VLAN 10 and VLAN20 , here are the configs for both switches. What am I doing wrong?
Current configuration : 1943 bytes

Our customer wants load-balance across unequal circuits due to the primary link being saturated. Primary link is 10Mb and backup is 4mb (multilink 2 x 2Mb).
I have tried implementing this using ‘variance’ under EIGRP on the 6500 switch but can’t seem to get both WAN routes in the routing table - unless I use the same metric on the route-maps we use for redistribution – e.g. set metric 10000 100 255 1 1500
If I do this the 6500 sees both routes but I’m concerned too much traffic will go via the lower speed link causing more problems. I have adjusted the delay under redistribution to make the 4Mb less preferred and I see this under ‘show ip eigrp top’ and thought the ‘variance’ command on the 6500 switch would work. But no matter what I set variance to it still doesn’t enter the less preferred route in the routing table.
I config the routers with EIGRP and also write Static route between two PC before remove the link between router0 and router1 , destination is reachable , but when remove this connection , packet from pc1 to pc0 will drop in a loop and never reach to destination , is it possible to have a Link state routing protocol and static route at the same network like this scenario , how to prevent loop in this topology static route is configure as bellow :
I have been playing around with Packet Tracer trying to understand EIGRP and to put it into practice. Well im not doing so well, I cant get the routers to form an adjacency therefore nothing is pinging outside of the routers. [URL]
I started studying yesterday for CCNP Route and I'm already stuck. Stupid Frame relay. Basic topology attached, 1 Hub, 2 spokes. I have EIGRP working correctly and each spoke can see all routes correctly. The Hub is on a Multipoint interface with split horizon turned off.
I have an ASA- 5585X (v.8.2.4) directly connected to an upstream 6509, which is running EIGRP. I configured the ASA for EIGRP with same AS# and network numbers and no auto-summary. Here are the log messages I got:
Mar 8 15:11:08: %PIM-5-NBRCHG: neighbor 126.96.36.199 UP on interface Vlan150 (vrf default) Mar 8 15:11:08: %PIM-5-DRCHG: DR change from neighbor 0.0.0.0 to 188.8.131.52 on interface Vlan150 (vrf default) Mar 8 15:11:11: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 1: Neighbor 184.108.40.206 (Vlan150) isup: new adjacencyMar 8 16:16:08: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 1: Neighbor 220.127.116.11 (Vlan150) isup: new adjacency Mar 8 16:18:54: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 1: Neighbor 18.104.22.168 (Vlan150) is down: K-value mismatch
I lost my SSH connection to the upstream 6509 and couldn't get it back. Luckily I didn't lose my ASDM connection to the ASA, so I disabled EIGRP and went to look at the logs on the 6509.
What causes a K-value mismatch, and how to I rectify the situation?
We have software router vyatta and about 15 branches with cisco 881w and cisco 1941. All branches have 10mbs bandwidth and 3 of them have 50mbs. Link to vyatta has 100mbs bandwidth and situated in datacenter.All branches connect to vyatta via vpn site-to-site with ipsec.I want to change vyatta to cisco router or asa.
I have a production L3 3750 stack with 2 WAN connections, which is connected to the companies WAN infrastructure using EIGRP.Recently there have been a number of hello drops from one site, which is causing the EIGRP adjacency to drop and so the whole site goes down from the rest of the WAN. Physical cabling has been replaced towards the ISP router, and the ISP have found no issues on their equipment or circuit.on occassions the utilisation is high on the link, so reasons for the hello packets to be not reach the end point, but other times the links are lowly used.The WAN links are active/standby, so the active is always used, but the EIGRP adjacency is dropped by both links.
I have two 2911 routers running 15.0(1)M4 in a redundant topology connected to an ASA 5520 firewall running 8.4 version. All gears are running EIGRP. In order to distribute the incoming traffic between the two 2911 routers, I am using 'offset-list out' on them, but in the ASA's routing table I see updates from both 2911 with the same metric, i.e. the offset-list is not working. What are the default metric weights on ASA? How can I change them? I couldn't find any known bug.
I have been able to get EIGRP working successfully in the lab like I want.
Attached is the network overview:
We have a Data Center and Corporate office connected via Point to Point Fiber link, eventually we will have two of theseTwo 4948E switches in the Data center acting as cores setup with GLBPCorporate Office has a 3750X acting as a coreCurrently two 4948E's are connected to each other via Port Channel and a L2 trunkTwo set of ASA 5520's one acting as a firewall and for Cisco Any Connect and second for site to site VPN What is the best way/pratice that I can distribute this DMZ via EIGRP? Should I just leave it static on the core like this?
We have problem con EIGRP and two ASR 1001 in High Availability. ASR2 have received all route (100 route) from PE, but in ASR1 doesnt received all route (75 route) from PE or from other ASR02. All PE have all route. The ASR1 when modify or lost some route dont update to the ASA. see diagram.
Customer has WS-X4013+ supervisor engine and want to use as redundant SUP for WS-C4507R-E. Is it possible to configure EIGRP then? The customer already has WS-C4507R with SUP WS-X4013+ and has configured EIGRP.
Does 800 series routers support OSPF or EIGRP? Command for EIGRP is available but when you try to run it, you get that "protocol is not available in the image". Is there a specific image that I can get that will support either of these two on a Cisco 851 or 861?
OPTEMAN: 3 routers connected via a private subnet (/29) over the OPTEMAN: Site A, Site B, and HQ. Site A is a 3560 that is the gateway for two subnets: siteA1 and siteA2. SiteB is a 2621, and HQ is a 6509 w/ MFSC.
HQ also connects to 4 other sites via MPLS: SiteC, SiteD, SiteE, and Site F.
HQ has the server subnet, Internet connection, and connection to other services via MPLS.
I have basic EIGRP setup on HQ, SiteA, and SiteB. So far only siteA and HQ are updating each other. Not sure why. I am looking for the best practice example of how I should setup my enterprise EIGRP. I currently use static routes between the sites. I would prefer to be able to setup EIGRP in parallel, the remove the static routes.
We have 2 ASA5510 and 2 ASA5525. Got a very weird error; up to release 8.4 eigrp works fine, after upgrading to 8.6 eigrp stops working.Can't see any neighbors; but same command from another asa on same network but with release 8.4: [code] I want to put the 5525 on production but would like to do it with latest release; could this be a bug on 8.6?
I have an ASA 5520 connected to a Cisco 6509E, and we're turning up EIGRP between the two. The problem that I'm running into is that there a few static routes (including a 0.0.0.0) on the core that's being redistributed into the EIGRP AS, and I need to block this from being propagated to the ASA. The ASA only has the capability to use an ACL in conjunction with a distribute-list, and I can't find a way to filter the default route (0.0.0.0 /0), while allowing everything else.
I need to configure BGP on our 7204 and 2811 router. The 7204 is our main router and currently running EIGRP internally. Our remote locations just moved to an MPLS connectivity and they have a 2811 router. I will need to configure BGP for the routing protocol. I have the AS number and the remote AS number. Attached is the the current configuration of the two routers.
I am looking to implement 25 Cisco 3750 switches with IPBASE image at the edge, across many cabinets. I understand I am limited to EIGRP Stub on the 3750 switches (with IPBase) and cannot acheive funding to upgrade to IPServices. Though I am not fully aware on the limitations, in terms of what I am trying to acheive.
Broadly speaking I want to install 2 x 3750 switches at the edge, with point-to-point links to two 6500 core switches (at the data centre) and then have HSRP interfaces on the 3750's, tracking the up links to the core switches. I am presuming this will be the best solution to ensure reliability.My 6500 switches run EIGRP and have many VLANs and other L3 networks advertised, which will need advertising to the 3750 switches. I would be looking to advertise two or three HSRP networks on the 3750 switches, up to the core switches.At the moment, the entire network is Layer 2 (VLANS + STP).
how to configure EIGRP across the 3750 switches and 6500 switches to allow for the 3750's to see the whole network and also advertise back up it's directly connected (HSRP) networks to the core. At the moment, after configuration, none of the switches see each other as EIGRP neighbours but can ping the L3 addresses on each end.
I have a problem with spurious loss of EIGRP neighbour relationships following the introduction of some IOS 15.1(x) into our network. Here's a rough diagram of the topology in question.
Core sites - summarising out RFC 1918 address space to branch. Core routers are 7206s running 12.4(24)T3
Branch has a fractional Ethernet primary link (4Mbit/s) and 4 private ADSLs using CEF load-balancing (per packet) as a backup link (bandwidth 2Mbit/s to branch, 1Mbit/s to core) These links are on separate routers connected at 100Mbit/s. This topology has been in place for some years without issue.
We've recently started putting in 2900 series routers running IOS 15.1(x) instead of 2811s running 12.4(x) in the 2nd buildings - Routers X and W in the diagram. Following that change we're seeing regular loss of EIGRP neighbours on the ADSL links, errors logged as folllows;
Jan 24 16:30:14.192 UTC: %DUAL-5-NBRCHANGE: EIGRP-IPv4 2: Neighbor 10.121.31.114 (ATM0/0/0.1) is down: retry limit exceededJan 24 16:30:16.852 UTC: %DUAL-5-NBRCHANGE: EIGRP-IPv4 2: Neighbor 10.121.31.114 (ATM0/0/0.1) is up: new adjacency
EIGRP packet debugging indicates that router X is periodically attempting to send an EIGRP update to router B. Router B does not log receipt of this update, consequently does not acknowledge it, router X tries 16 times and tears down the neighbour relationship. It's brought back up a varying but small number of seconds later with the exchange of EIGRP hellos - which seem to be fine throughout.
I've been able to reproduce the problem as described by upgrading a working 2811 running 12.4(13a) to 15.1(3)T with no change in config. Downgrading it back to 12.4 again removes the problem. In fact, when running 12.4 the normal state is for no EIGRP updates to be generated by router X. I can contrive to force an update by configuring static routes on routers W,Y or Z and the updates are exchanged and acknowledged normally between router X and router B. If I shut down router X's LAN connections to router W and the adjacent switch, so router X becomes just a spoke on its ADSL links, the problem does not occur.
We only see the problem on ADSL links right now, I'm unable to confirm yet whether we'd see the same if it were another shaped Ethernet link connecting the 2nd building to the core.
The problem is also apparent when running IOS 15.0(1)M3 on router X.
I've gone through the Bug Report list on CCO and not found anything similar to this. The only documented significant difference in EIGRP defaults I can find between IOS 12.4 and 15.x is that no auto-summary is now default.That's not relevant here though because we explicitly turn it off in IOS 12.4.
So, what I could try to make EIGRP operate seamlessly with older IOSs on 15.x.
I have 3750 switch and there are couple of vlans.....i dont want to run the instance on all vlans....so i have decided that i will run passive intreface default command....now my lan link is layer three and i want to run eigrp on that so the command shd be as under?
no passive interface default interface gig1/0/10 no passive interface default interface gig1/0/22
(as i have 2 conections) and want to have two neibours.
1.Cisco IOS Software, C3560 Software (C3560-IPSERVICES-M), Version 12.2(25)SEE2, RELEASE SOFTWARE (fc1) This switch EIGRP coverge is slow. 2.Cisco IOS Software, C3560 Software (C3560-IPSERVICES-M), Version 12.2(35)SE5, RELEASE SOFTWARE (fc1) This switch EIGRP coverge is fast
The IOS have effect of the EIGRP coverge ? From which version IOS began ?
I get some EIGRP flapping on my CE router (c2921) 2 sub interface to another two site. The router IOS version "c2900-universalk9-mz.SPA.152-2.T1". I capture the debug log as attached. I know understand some log meaning from the debug.
Why is there no DR/BDR concept in EIGRP multiaccess networks? If the purpose of a DR/BDR is to limit excess traffic when there is a change in the topology, why isn't there one in EIGRP? I understand that DR/BDR share LSAs and not routes but the concept is still the same: there is a change in the topology and the change gets flooded to all neighbors, those neighbors in turn flood it to their neighbors on the multiaccess network thus causing excess traffic.
i have a problem in my eigrp configuration that the other branch only see the network that i am advertised in eigrp and can't see the the redistibuted static route inside eigrp .. i dunno why is thatand that's my running.
