Cisco WAN :: EIGRP On L3 3750G Is Not Working

Feb 23, 2011

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
version 12.2
no service pad
service timestamps debug uptime
service timestamps log uptime

Cisco Switching/Routing :: 3750G ACLs Not Working

Sep 17, 2012

I am trying to create an ACL that walls off a VLAN and only allows it to the internet. This is on a 3750G, currently the 3750G I am attempting this on is in a stack. I have another 3750G that is a standalone.
The first way I attempted this was to create two access-lists: access-list 101 permit tcp any eq 80 access-list 102 permit tcp any established
Let's call the VLAN 2. I applied this to the VLAN2 interface, 101 out, 102 in. It didn't work. If I place a deny statement with nothing else, that works.
The second attempt was this: access-list 101 deny ip any access-list 101 permit ip any any
I applied this to a VLAN I wanted to block VLAN2's traffic from reaching, let's call that one VLAN 3.
This lets all traffic from any VLAN (including the one I'm trying to block). If I remove the "permit ip any any", then all VLANs are denied. Which I understand is correct due to the implied deny all. What I don't understand is why it isn't applying the ACL to the specific VLAN.

Cisco Firewall :: ASA 5540 Load-balancing Over EIGRP Not Working

Nov 15, 2011

We have an ASA 5540 running 8.4(1) on the inside of dual Internet-facing border routers. The routers run BGP facing out and EIGRP facing in, with the ASA also running EIGRP for the same AS. Both routers redistribute a default route into EIGRP. It was my understanding and expectation that the ASA would learn both of these, as they are equal cost, and load-balance the outbound traffic over the two links. This does not appear to be the case.
The routers both have:
router eigrp 100
network nn.nn.nn.nn
redistribute static

Cisco WAN :: 881 EIGRP Missing?

Aug 25, 2011

We use all Cisco router in our business mostly 1841 and 871.   But now i'm currently working with a new router:
Just purchased last week - Cisco 881
The Cisco IOS is:

Cisco IOS Software, C880 Software (C880DATA-UNIVERSALK9-M), Version 15.0(1)M6, RELEASE SOFTWARE (fc1)

->System image file is "flash:c880data-universalk9-mz.150-1.M6.bin"
As all our router are Cisco we use EIGRP as our routing protocal.  But with this router all I see is:
#router ?
odr  On Demand stub Routes
rip  Routing Information Protocol (RIP)
Where is my EIGRP ? I can't configure eigrp, so my router wont be doing much routing.

Cisco WAN :: 6509 - 10 Gig EIGRP Metric

Oct 3, 2006

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?

Cisco WAN :: EIGRP Variance In 6500

Jul 19, 2011

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.

Topology is as follows:
       |----2800---WAN (10Mb)
____|----3640---WAN (4Mb)
We use BGP on the WAN and redistribute into EIGRP on the LAN using route maps as follows:
2800 (10Mb)
router eigrp 5555
redistribute bgp 888 metric 10000 200 255 1 1500 route-map bgp-eigrp
no auto-summary

Cisco WAN :: 3750G LC To SC Conversion

Nov 1, 2011

I have a core switch Cisco3750G with 4 SFP slot populated with GLC-SX-MM module.Now in these 4 fiber GLC-SX-MM modules 3 are connected to 3 floor switches which are having the same GLC-SX-MM.Each link is configured as a TRUNK and allowed only that floor VLAN and working fine.Now the 4th GLC-SX-MM module has to be connected to a single desk top PC using a FIBER to UTP convereter,which is SC to UTP .Now patch pannel is LC ,I used a LC to SC fiber patch cord,but link is not coming up,in this situation if I used both side SC convereter then link is up.
All 4th GLC-SX-MM modules are checked and it is working fine.Only the forth floor link is not coming up,if I use the UTP to Fiber SC type connector in the CORE switch for teh 4th Floor then it is working.How to resolve this issue,Whether I need to use the UTP to Fiber LC type convereter in the fourth floor instead of SC type converter,logically when I use the LC-SC type patch cord and connecting to SC type converter it should work.

Cisco Firewall :: K-value Mismatch With EIGRP On ASA5540

Mar 7, 2011

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 UP on interface Vlan150 (vrf default) Mar  8 15:11:08: %PIM-5-DRCHG: DR change from neighbor to on interface Vlan150 (vrf default)

Mar  8 16:18:54: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 1: Neighbor (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?

Cisco WAN :: 3750 EIGRP Adjacency Dropping

Mar 3, 2013

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.

Cisco Firewall :: EIGRP Metrics On ASA 2911

Aug 4, 2011

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.

Cisco WAN :: 2621 - How To Setup Enterprise EIGRP

Dec 19, 2011

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.

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), while allowing everything else.

Cisco WAN :: 3750 / EIGRP Stub At The Edge?

Apr 24, 2012

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.

Cisco WAN :: 7206 - EIGRP Behaviour Change In IOS 15.1(x)

Jan 24, 2011

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 (ATM0/0/0.1) is down: retry limit exceededJan 24 16:30:16.852 UTC: %DUAL-5-NBRCHANGE: EIGRP-IPv4 2: Neighbor (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.
