this is a Nexus 5596 L3 with the latest code:
It looks like the deny statement is not working as I can see all routes I am redistributing. I even did a deny on a specific route and I still see it in the routing table on another router in the autonomous system.The same below works fine on IOS platform. [code]
I'm attempting to redistribute a static route into EIGRP on a 3750 switch and pass it to an upstream router, sadly however this isn't working, or at least the route isn't being recieved on the upstream router. [code]
View 10 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.

View 4 Replies View RelatedWe have setup a pair of Nexus 5596 L3 switches with 2 x 10Gbps LACP links between them to act as the vpc peer link. We also have another 2 x 10Gbps LACP links between the 5596 switches to carry non VPC VLANs, this is required to provide EIGRP routing between the switches and an upstream router.I have read that it is possible to setup the vpc keep-alive link over an SVI instead of the management interfaces. Is it ok to run the keep-alive SVI over the second LACP non VPC VLAN trunk or is it recommened to keep this seperate?

View 4 Replies View RelatedI am looking to see if Nexus 5596UP & Nexus 2248TP GE compatible with SFP-10G-SR? The reason is because a consultant was hired on to "design" the network layout and has decided to purchase Cisco SFP+ Copper Twinax Cables which have a 10M limit. A small handful of the Data Center racks are 10-15M away... just out of reach of the Twinax. I would prefer NOT to move the LAN row so that it is more centered in the room. Can I use the SFP-10G-SR to connect the 2 switches (5596 & 2248) together? This SFP has a 26M reach on standard 10gig fiber, the small cost increase per connection is of no concern.

We have HSRP between NexusA and NexusB with access layer switches connecting to the core using VPC, We are trying to setup a VAM server Voice recording for Siemens phones. We need to span all voice vlan and point it to the VAM server the VAM server connects to a 3750 Stack considering the amount of traffic multiple span session can generate I plan to move the server to the Nexus directly and run a Local Span Session.
1- As we have two Nexus running HSRP and VAM server only connects physically to one NexusA (I can run local span on that nexusA) the Second NexusB is not directly connected to the VAM server I plan to run ERSPAN so if this is the best design and which path will the span traffic take from Nexus B to NexusA will it go through the access layer switches depending on the vlans allowed on the uplinks or will it go through the 20 Gig uplink between the two Nexus allowing all vlans (VPN peer links) ? WE have approximately 10 voice vlans, Do we an example config for ERSPAN session where the source are vlans (As I am for fimilliar with RSPAN) ?

I'm running version 5.1(3)N1(1) on both of the 5K's. I have looked through all the configuration and I am not understanding why I am getting this error. I have tried to look it up on [URL], but not having a ton of luck.
I have 2 datacenters running same equipement (two Nexu 5596 with FEX).I just took a look at the log just to see if everything is ok and I saw that I have the same error message (a lot of times) at both location :
%SYSMGR-FEX100-5-HEARTBEAT_LOSS: Service "satctrl" heartbeat loss 2 ,max 7,I though it was a problem with my peerklink-keepalive connection but I see the word FEX ....so i'm not sure...
Note that at both locations, my Nexus are connected back to back through the management port using transceivers. So it's a copper cable from the first nexus, going into a transceiver, going to another transceiver in fiber and then back to copper to the other nexus.

We're looking into Nexus to replace these switches in the long run.
i want to remove the sync-profile on each of two synchronized Nexus 5596UP without loosing the config stored in Switch-Profile. That means without connectivity interruption and re-configuration of interfaces in "conf t mode", for example. Since NX-OS Release 5.2(1)N1(1) there is a new command
switch(config-sync)# no switch-profile abc profile-onlyprofile-only—Deletes the switch profile without the local configuration.

I have a customer with a primary datacenter and DR datacenter, that has a P2P 100Mbps link connection between them. At the primary Datacenter there will be a Nexus 5596U with a L3 card running EIGRP, it will have three connections, one nothbound to the Internet not a problem, the other is north bound to an MPLS SP managed ISR router. Both datacenters will have MPLS SP managed ISR router, the MPLS service provider will be redistributing BGP into EIGRP from their ISR routers at both datacenters. This means we will learn external EIGRP routes with an AD of 170.
Connected to my 5596 southbound will be the SAN for the EMC storage traffic, the DR also has a SAN with EMC storage as well. The 100Mbps P2P link is primarily for replication traffic.
Since the Nexus 5596U with L3 module doesn't support PBR I have to figure a way for replication traffic to prefer the 100Mbps P2P link vs the MPLS cloud. I was thinking of running iBGP over the P2P link with the Nexus 5596 being a route reflector and it's iBGP peer which will be a Catalyst 3750X at the other end of the P2P link being the route-reflector client. That way both iBGP peers will exchanged learned routes.
I have to come up with a way for the replication traffic that comes sourced from the IP addresses of the EMC/storage to prefer the P2P link which will have an AD of 200 from iBGP in the routing table vs the external EIGRP traffic that has an AD of 170 in the routing table. All other traffic will route normally across the MPLS cloud. All other traffic will include client server traffic as there are application servers that sit south bound of the Nexus 5596, the client traffic will come inbound to the datacenter via the MPLS cloud.
I don't have a Nexus 5596 to do a mock lab. My thought is to redistributed connected with a route-map in EIGRP on the Nexus 5596 with a two match statements then set the IP next hop to the IP of the 3750X. I would need to select only replication traffic, so I was thinking if I can match on vlan and next-hop then my set command would be the next-hop of the 3750X.
the phone connects to the 3750-A access layer switch (VTP mode client) which connects to the nexus 5596 (The nexus is the layer 3 device and set to vtp mode server) and finally we have a Voice recorder that connects to another access layer 3750-B switch.(VTP mode client)
For voice recording I need to setup RSPAN and the nexus5596 does not support RSPAN will the following have any impact on the nexus
IF I move the 3750-B to VTP server mode and run the command remote span on the VLan I need to Rspan its going to update the VTP data base in short it will update the vlan.dat file for all the switch in that VTP domain.
AS the vtp update reaches the nexus saying there is a change (keeping in mind the nexus does not support rspan not sure hows its going to handle that request and how its going to update its vlan.dat file)
Is it going to incremment the VTP revision number? can it crash the vlan.dat file on the nexus ? or do nothing and ignore the update and stop the update from proceeding to the 3750 A switch?
I have a 3750 at a branch running EIGRP connected to two routers that both have configured:
access-list 1 deny 0.0.0.0
access-list 1 permit any
access-list 2 permit 0.0.0.0
access-list 2 deny any
router eigrp 1distribute-list 1 out FastEthernet0/0distribute-list 2 in FastEthernet0/0
Due to this recently applied config the switch become unreachable from the outside and cannot ping anything. Everything connected to it works fine. I was able to remote into it from a switch behind it and noticed that the 3750 has no default route in the routing table. I do see a default route in the eigrp topology table. How to make the switch learn a default route maintaining the existing configuration on the routers.
I'm trying to create a route-map for an EIGRP Distribute list on a N7K, the goal is to not advertise a 10.0.0.0/8 and 172.31.30.20/32 networks out a link to a remote site while permitting all other traffic to the internet (default). I configured the ACL/route-maps below and applied them outbound on the N7K interface but no subnets at all are being received on the remote site router.

We are deploying a new office in the building next to our main office. The main office has a Cisco ASA 5510 behind that is a Cisco 3750 stack. In the new office we are deploying a new Cisco 3750, they will be connected via fiber cable. I have sliced off VLAN 800 as a transit link /30 with an address space of 10.249.249.1-4. The new 3750 only has two VLAN's 800 and 112 (10.112.0.0/24). VLAN 112 routes are advertised to the neighboring 3750 properly as seen in the routing tables of the 3750 stack:
D 10.112.0.0/24 [90/3072] via 10.249.249.2, 00:22:24, Vlan800
Traffic passes between all local VLANS with no issue. I found in order to get packets to pass between the ASA and the new 3750 I had to add a static route to the ASA:
S 10.112.0.0 255.255.255.0 [1/0] via 10.100.0.1, inside
My question is why is EIGRP not advertising the 10.112.0.0 network to the ASA. Here are EIGRP configs on the switches

I have an issue with my setup of a 6500 switch (12.2(33)SXI9).We have a 6500 switch with several VRF's. For a certain VRF I would like to redistribute a static route in EIGRP. After doing so I don't see the static route on my eigrp neighbor.
This is a overview of my config. I'm basically redistributing only my static route for this vrf in eigrp.
I found a similar case in which the solution was adding a metric to the static route. (eg. redistribute static route-map static-eigrp-pp metric 10000 100 255 1 1500). But the strange thing is that we don't have this issue on a similar machine (same IOS, same config setup). [code]
We have, for nearly 4 years, used EIGRP on our 6513 to make use of two unequal links to our branch offices. This worked because we could use the variance command and cause EIGRP to insert two routes into the table, one from each carrier. Thus it was we could balance the load to each one with a ratio similar to the ratio of the bandwidth of Link A to Link B.
We just purchased 2 Nexus 7010's to replace our single 6513 core.After much consternation we have found from our Ciscio SE that the Nexus 6.0.2 software rendition of EIGRP does not support variance.
Why would Cisco take their own propriatary protocol and then gut it by removing features? I'm quite ready to send these Nexus boxes back in favor of a newer 6500 series. MEC doesn't work like it is supposed to and the show-tech runs for over 24 hours without ever finishing (and this we can repeat on both boxes, multiple times).
We've opened a tac case but I just wondered for any work around for the 'variance' command?
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:

192.168.168.0 172.30.255.22 1374 0x80001a45 0x6c5b 0
The routing table shows:

View 1 Replies View Related For a simple 4x sites design for backup consolidation (3x sites connected to one central site), does the design in the attached JPEG make sense and is the configuration achievable using the specified parts?
Brief Explanation:
- Each site is to have servers with 2x 10Gb/s Ethernet (both teamed/bonded/etc) and one NIC on each of the 2x switches in the site (if possible). Each site will also have 2x Cisco Nexus 5596UP Switch (though the P version may be used instead of the UP).
- Two of the sites are within 10KM of the central site
- The last site is about 35KM from the central site
- It is required to have a minimum bandwidth of 10Gb/s between any site and the central site
- I have specified 10Gb/s LW SFP+ and 10Gb/s LW SFP+ (for the 2x 10KM and 1x 35KM sites)
- are there any special licenses needed?
- as asked before, can such a "simple" design work as-is?
- what sort of single-mode fiber would fit the bill (especially for the 40KM link) - 9nm?
