Cisco Switching/Routing :: 6500 / Nexus OSPF Process Limit?
Jan 11, 2012We 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.

Cisco Switching/Routing :: Multiple VPC Domains On A Single Nexus 7000?
Nov 13, 2011I have a customer with three rooms where teh access layer aggregation switches are run back to.
Access Switch Stack A -> room 1 + room 2
Access Switch Stack B -> room 2 + room 3
Is it possible to have three Nexus 7000s ie one in each room (1,2 and 3) and have them setup like this:
Nexus 7000#1 vPC domain 1
Nexus 7000#2 vPC domain 1 + vPC domain 2
Nexus 7000#3 vPC domain 2
Thus gving all access switch stacks redundant links to the core withouit spanning tree.
I know its not ideal but its a campus site and thats how the existing fibre runs go.

Now i want that SERVER1 should be able to speak to SERVER2 and SERVER3 and i want to exchange routes betwene VRFs through OSPF.
Cisco Switching/Routing :: Does Nexus 7K Support Multiple VDCs Sharing Ports On Single Line Card
Mar 19, 2013Does Nexus 7K support Multiple VDCs sharing ports on a single line card. One of our cisco parnter engineers stated that cisco doenst recommend using same line card for multiple VDCs.The second VDC (Non-Default VDC) will be used four our Outside, and DMZ Segment, and to phyiscally segregate our Firewall from our Internal/Inside Core Switch without using a physical DMZ Switch.I know Cisco used the Nexus in this way in their PCI DSS 2.0 Compliance Document. Module is N7K-M148GT-11L

Cisco Switching/Routing :: Test Multicast Between VRFs Configured On Nexus 7Ks?
Jan 11, 2012We are trying to test multicast between VRFs configured on Nexus 7Ks. Two Nexus 7Ks are configured for VPC. Multicast Server is in one VRF where as Receiver is in another VRF. The two VRFs are connected to each other via Checkpoint Firewall (Active/Active cluster in unicast mode). All routes have been established and connectivity tested between multicast server and receiver using ICMP.Using, windows mcast.exe multicast stream is generated from server (in one VRF) intended to be received by receiver (in second VRF). Every time, only one multicast packet is received by the receiver and rest all packets are being dropped. Server and Receiver are VirtualMachines configured on VMWaresame chassis which is connected to two Nexus 5Ks (VPC configured).

Jan 2, 2012I've been reading the documentation for the new 3750v2 switch, and I'm wondering is the IPBase license supports FULL OSPF. The product sheet notes that it supports OSPF in the IPBase license, but then further down the page it notes that for advanced routing functions (EIGRP,OSPF) you need the IPServices license. Are there any limitations to the OSPF process on a 3750v2 with the IPBase license?
View 3 Replies View RelatedCisco Switching/Routing :: 3570 / Multi-process OSPF Redistribution And Failover?
Feb 7, 2013I have two ospf processes running on a single 3570 edge router that has a dedicated transport circuit back to our network core. We are adding an additional "transport" only circuit into a new location that is also apart of the second ospf process backbone which will connect back to our core. There will also be a 3750 for this new circuit termination. Currently we are only redistributing ospf process 2 into ospf process 1 (1 = core backbone).
#router ospf 1
#redistribute ospf 2 subnet
We have no need to have ospf process 1 redistributed into the process 2 tables. That being said, when we add an additional transport ciruit, or path back to our core backbone, will this configuration present any issues with the redistribution process and failover.

Cisco Switching/Routing :: Nexus 5596 UP L3 OSPF
Jan 3, 2013I 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 RelatedCisco Switching/Routing :: Redistribution Of Statics Into OSPF On Nexus 7000
Feb 15, 2012I'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.
Cisco Switching/Routing :: Nexus 7K Ignoring Received OSPF Route?
Mar 25, 2013I 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:

Cisco Switching/Routing :: Nexus 7010 - Stop Default Static Redistribution Into OSPF?
Sep 24, 2012Ok 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?

Cisco Switching/Routing :: Nexus 7010 OSPF Passive-interface Default Not Showing
Nov 6, 2011I'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.
Cisco Wireless :: 5508 Assign Single Ssid To Multiple Interface Groups By Assigning Ssid To Multiple AP Groups
Aug 26, 2012Is it possible to assign a single ssid to multiple interface groups by assigning the ssid to multiple AP groups?
I have buildings geographically dispersed that are configured with multiple vlans in interface groups so that I can maintain an addressing scheme of dhcp assigned addresses per building. Each building is also further grouped as AP groups. I'd like to know if by assigning the same wlan ssid to each of the AP groups, will I maintain addressing integrity for each building? I'm thinking it will work.
Do the buildings have to be outside AP range of each other to avoid problems?

Jul 22, 2012I currently have mutiple computers at my place. Once the computer turned on i want the option of which login for the current computer to use, it can login it current computer or the mutiples computer with their content/data all inside. So more like an computer linked. Example, it can only to A or B, A is the current computer data, while B have all the data of the different computer monitor datas, and if i login B it will show that current computer info. And same goes to the B computer, i can login to A or B on the B computer. What makes this very good is that, both the computer logins are sort of connected, for example if im on actual computer A, but logined to computer B and downloaded/changed some files/data on the B login, once i login on computer B to login B, the changes will apply even tho the changes are done in computer A.
