Does the Nexus 5548/5596 switch support OSPF ECMP?
Also on OSPF and ECMP, the load-balancing method at the multiple links for Catalyst 3750 is per IP packet or per destination IP?
Nexus 5500 support auto negotiation on 1gig sfp port? There is an end device that only support auto negotiation and cannot be manually set speed/duplex.
View 0 Replies View RelatedI have 2 Nexus 5596UPs with a layer 3 cards that are exhibiting some very peculiar behavior. The systems are running 5.1(3)N1(1).I have configured 2 VRF contexts each running their own OSPF process. There is a static gateway of last resort configured on each VRF, which is to an upstream pair of 5585X's in Active/Active. Each OSPF process has the "default-information originate always" command configured, however, backbone neighbors are not recieving a gateway of last resort from the 5596UPs. The applicable configurations are show below. All other routing information is passing correctly between devices in the network. This network is not production, it is a proof of concept for a larger implementation.

if I have 6509-E with VSS-SUP720-10G and want to run OSPF and BGP on the Switch. What is the IOS i require? WIll IP Base Suffice or i need to take Advance or Enterprise Image.
I acquired a 3560X-24P-L Switch which I wanted to use at our datacenter. However, I need a switch that supports OSPF. It came with a Universal IOS but there was no "Router" command under conf t. I downloaded and applied the latest "IP Base" IOS, but still no Router OSPF. Based on the matrix here > [URL] I thought "IP Base" supported OSPF, but what exactly is "OSPF for routed access" ? Do I actually need an "IP Services" IOS? From my download options, I do not see an IP Services IOS for the 3560X-24P-L so I'm left to assume that the switch does not support L3 / OSPF. So my question is this particular switch supports L3 / OSPF and what is Universal IOS?
View 5 Replies View RelatedWe are cutting over from 6500 IOS to Nexus 7000 and have hit "Maximum ospf feature instance limit reached." as we configured up the 7 existing ospf processes - the limit is 4. These existing processes are for various vrf contexts we have. I see you can run multiple vrf contexts under one process - but how does that work in a mixed environment where the ospf neighbours are still ios 6500s? They still expect to see different ospf process id per vrf.
View 2 Replies View RelatedI'm looking to redistribute static routes in to OSPF on a Nexus 7k. To do this I'll be using a route-map with a match statement. My question is can you match routes using an ACL, a prefic-list or both. The reason that I ask is that in some docs I've read it states the following:
IP access lists—(For policy-based routing only). Match based on source or destination IP address, protocol, or QoS parameters. This tends to indicate that you can't use IP access lists for the match criteria for redistribution.
I have a Catalyst switch that is redistributing some static routes into OSPF. These are received on a Nexus 7K and appear in the database however the 7K does not add them to its routing table, one of the routes is ignored and not added. I haven't got a clue why this is happening.
The routes on the Catalyst are as follows with ID of 172.30.255.22:
ip route 172.24.59.0 255.255.255.0 10.56.7.46
ip route 192.168.168.0 255.255.255.0 10.56.7.62
on the 7K the database shows:
172.24.59.0 172.30.255.22 1374 0x80001a44 0x1a48 0
192.168.168.0 172.30.255.22 1374 0x80001a45 0x6c5b 0
The routing table shows:
sh ip ro 172.24.59.0/24IP Route Table for VRF "default"'*' denotes best ucast next-hop'**' denotes best mcast next-hop'[x/y]' denotes [preference/metric]

I have an environment where i have two nexus 7010 switches, along with 2 nexus 5510's. I need to run OSPF as a layer 3 routing protocol between the vpc peer links. I have 1 link being used as a keep alive link, and 3 other links being used as a VpC link.
1) Is it best to configure a separate Vpc VLAN i.e 1010
2) Is it best to configure a vrf context keep-alive
3) just have the management address as the peer ip's.
OSPF normally only comes with IPservices image and not IP Base image. The 3560-C series data sheet says that it only suport IP Base image, yet it mentions that support for OSPF in included. Are there any restictions in the OSPF support?.

How to you setup ip routing on a Nexus 5500 I want to do vlan routing between an Nexus 5500 and Catalyst 3750. Nothing clever just have the 2 switches talk and vlans route between the two.
View 3 Replies View RelatedIs there an official Cisco-Page with the always-up-to-date recommended NX-OS-Releases for the Nexus 5000, just as there is URL
If there is no such page: What Release can be recommended?
We got new N596 & N2232 this week, and are using L2-LAN only, no L3,no FCoE- or FC-Ports. The command 'vPC orphan-ports suspend' is the newest feature used, so 5.0(3)N2(1) would be the oldest possible release.
Before I install 5.1(3)N1(1a) and then have to do a distruptive downgrade to 5.0(3)N2(2b), I'd like to be assured that the new one is already recommended as mature enough.
I believe the answer is yes, but incorperating more layer 3 features of our 3750's, I want to know if they fully support EIGRP or OSPF?
Also for a small business of 4 locations, each with a 10mbps fiber and a 1.5mbps mpls... wouldn't you say EIGRP would be easier? Want to look at making the failover automatic if the 10mbps fiber goes down between a site, then the network fails over to 1.5mbps mpls. When the fiber returns in service then the network automatically preferr the fiber again.
Currently we use static routes and if there is a provider outage we have to manually edit the config to flip flop the routes.
I'm trying to work out if I need to order the "IP services" image for a couple of C3750-X. I need to run OSPF on these switches, but find the IOS image requirements on Cisco contradict.
At the top of the data sheet it says: • Open Shortest Path First (OSPF) in IP Base image
On the product info page it says: IP Base: Enterprise Access Layer 3 Switching, including OSPF (Open Shortest Path First) for routed access
But in lots of other places it says you need 'IP services' for OSPF.
As the IP services IOS is quite a bit more expensive I would like to avoid buying it. What image do I need to run OSPF?
How many VMs can a pair of 5548s support? Remember, for each VM, I will have an ARP entry in the 5500 ARP Table (assume 5500 is the L3 default gateway).
View 3 Replies View RelatedOk I didn't setup my OSPF on my 7010. Today I found out that any static route I put into my 7010 gets sent into to my MPLS network. My 6509's you have to "Tag" the static rout for this to happen. Was under the impression the same was necessary for the 7010 or at least it had to "match" an access list. How can I fix the below so that by default all static routes are not resdistributed into OSPF?
[CODE]...
I'm currently working on a plan to migrate our 6500's over to our new 7010's. At the time of the migration I want to tighten up our OSPF design and configure OSPF for "passive-interface default" then allow only those interfaces that should have OSPF neighbors to send the hellos. The issue is that the command is not showing up under the OSPF process. What's even more interesting is that the Nexus 5.x Unicast Routing Configuration Guide shows that the "passive-interface default" command should be an option to enter.
I'm currently running version 5.1(4) (though looking to upgrade to 5.2 during my migration testing). I would rather configure the passive-interface via the routing process versus having to enter it on every interface.
IOS we used for limiting access for a group we used configuration of snmp-server views like following
snmp-server group backupgroup v3 priv read backupview write backupview access 20 snmp-server view backupview ccCopyTable included could not find out how to achive this config in NX-OS on Nexus5500
Are there any dependencies on VTP on the Nexus platforms like the 5500 or 7000? In IOS P V LAN required VTP Transparent mode however I cannot find any reference to this for the Nexus platform. Are there any other features that would require the use of VTP? By default VTP is turned off on nexus and has to be enabled with the feature command so is there any benefit to running VTP in transparent mode vs off?
View 1 Replies View RelatedThere is very little and quite diverse Information regarding the if, where and how of a Nexus 5000 or 5500 series Switch and support for IEEE 802.1AE Link Layer Encryption (also called MACsec).
For example: the official FAQ denies that the Nexus 5500-series supports 802.1AE at all, while the data sheet says that only "downlink ports" are supported (host access).
On the Nexus 7000 platform the 802.1AE link layer encryption is part of TrustSec (feature cts) and much better documented.
The Question is: If and under which circumstances (configuration, L3 modules, license, NX/OS version) does a Nexus 5k or 5500 series Switch support 802.1AE on 1G or 10G interfaces that are directly connected to a Nexus 7000 (with the necessary cts feature licensed/configured)?
I have run into a problem testing static route failovers using ECMP. I have an edge device (SUT) that has 2 NIC interfaces to an internal Loopback. Each NIC is a unique Gi port on an 7609 VLAN tagged with unique IP subnets. The 7600 is configured to route the loopback via the 2 NIC. I am using CEF in the network for other traffic performance testing. Using an external sniffer we can verify that when a ping is initiated externall to the SUT loopback a specific path is selected by the router.
Ping host ------Network-----7609 Gi1/21 (172.16.110.9)-----------SUT Nic1 (172.16.110.10)
| |
| -------Loopback 137.168.68.114/32
| |
7609 Gi2/21 (172.16.110.73)------------SUT Nic2 (172.16.110.74)
[code]....
Now, when the selected path is taken out of server (pulling cable for example), the 7609 is not clearing the routing table to indicate that particular path is down and failing over to the secondary path. Other things I have noticed is the show ip cef still shows both peers as well as the arp table but the interface shows down (show interface gi1/21 for example). I am running 15.1. My understanding is that since the ports are directly connected to the router, the ports should be detected as down and any association of the IP for the down port should removed. This should trigger the static route to update the static route for the end destination to use the second path and traffic should continue.

I am experiencing inconsistent echo-replay from devices connected via VPC to Nexus 5500s while pinging from the Nexus exec prompt.
In some cases I receive normal response when pinging from one Nexus, but no response when pinging from the other switch. In other instance I receive normal response to one Nexus, and duplicate replays to the other. It looks like a VPC related bug. NXOS is 5.1.3.N2.1

I have a Nexus 5500 which is the core of our network and we have access layer switches uplinked to it. I know by default the qos markings will be trusted.
1. On a trunk uplink from an access layer switch to the Nexus, I have "mls qos trust dscp". Will the DSCP marking be preserved when it reaches the Nexus?
