I am in the datasheets page for Cisco 3560C Compact switch and states that it ships with IP Base image that "includes the support for routed access, MACsec, and Open Shortest Path First (OSPF)"
[URL]
Does this image come with the full fledged OSPF feature or is it a cut-down version of it?
If i look at the Feature Navigator , it says that IP Base Supports OSPF and EIGRP. But if i look at the Cisco Link it contradicts the Cisco Feature Navigator.

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 just want to know how many ospf routes a catalyst 3740 support ?The cisco doc or datasheets doesn't answer this clearly. Because there is only a statement "unicast routes"!? Does this means all unicast routes (eigrp, ospf....static)If so, there is a statement for about 10k routes ?
View 3 Replies View RelatedI 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 RelatedOSPF 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?.

Also on OSPF and ECMP, the load-balancing method at the multiple links for Catalyst 3750 is per IP packet or per destination IP?
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?
I have a PS3 connected to a Gig port on my 3560. When I boot-up the PS3 I have to wait around 30 seconds for it to get DHCP.
I noticed the orange LED would stay on and go green after 30 seconds. I assumed I would have an error-state but I do not, the port show connected with no errors even though it's orange. I have no connectivity from the ps3 until the light goes green and then all is well. The port is access and I have manually configured duplex and speed.

I have an office that I need switchports for 24 cubicals that need 2 network ports each with POE. The problem is due to my cable path the switches need to be right at the cubicles themselves and they need to have no noise.
The compact switches are quiet enough but in order to get the density I need I will have to use 4 3560C-12PC-S and they don't have stacking cables.
My question is, is there a POE enabled switch that is larger than 12 ports or has stacking capabilities or is the 3560C-12PC-S or 2960C-12PC my only options?
I have 2 ASBR routers, AGFR01RTR03 and AGFR02RTR03, performing OSPF to OSPF redistribution in both ways for the same ***. They also do summarization for our private addressing scheme. It is all working just fine for that part (neighbors, summarization, redistribution).

Currently the OSPF network consist of 2 segment route via static route.One is AREA 0 and another AREA 10.Both network are seperate entity, only static route to route between 2 networks.But the static route do not provide the dynamically and flexibility, I plan to run routing between 2 networks via VLAN160 and VLAN162.

View 7 Replies View Relatedimplement backup WAN links to complement the metro Ethernet links we currently use so we have some redundancy. These will most likely be a VPN over an Internet service but might be another Ethernet type service, the medium shouldn't really matter I wouldn't think. What I am looking for input on is what is the best way to implement this? Would I just set costs so that the backup is only used when the primary goes down, or should I create new OSPF area for the backup links?
Currently the core switches that are also our routers are 3750G stacks running ip services. We are getting ready to install new firewalls at each location that will become the gateways for the vlans currently on the core switches to give us much more control over segmentation, and because of this I am thinking that it may make sense to then move the OSPF instance from the core to the firewalls. In the drawing I did not show the access layer switches off of the core, and the MOE circuits actually terminate into a 3550-12T switch before the core. I think I will actually eliminate those 3550-12T switches and go straight into the core. This is a current state drawing, so does not include the backup links I am planning.
I have 10 different segments in ASA 5520, so i created 10 VLAN in ASA & made the inside interface as Trunk that connects with core switch. Now i need to run OSPF in the ASA.
View 1 Replies View RelatedI will be getting a WAN connection to a few offices and I have a need to control routes recieved and advertised to/from them. The service provider will be placing a CPE device on-site and will support OSPF with my edge router; in this case a Cisco 2821. That 2821 router will ideally be configured with OSPF routing toward my two core switches.
-> C2821 to NOT have the full routing table from the Core switches
-> Only needs knowledge of two routes from the Core switches and routes from remote offices.
-> Controlled routing advertisements. I do not control the remote offices and would like to ensure they do not accidentally advertise routes into my enviroment that could create a conflict.
I'm assuming the Service Provider will be running BGP on their CPE router, which will mean that the OSPF routes recieved by my Cisco 2821 edge router will be OSPF E2 routes. So if thats the case the 2821 would need to advertise E2 routes.I'm not sure if I should be configuring the 2821 in Area 0...because its meant to be a WAN edge router; but if I configure it in another area...say 200...the Service Provider may configure his CPE router in Area 0...which I'm guessing would pose a problem as the 2821 would be lodged in between two area 0s?
From the reading I've done it sounds like I could use NSSA...but I'm not sure if this is the best design.
Looking through the SPROUTE course material they state on several occasions that an ABR will announce a default route in to a standard NSSA area, same as a stub area, because LSA5 external routes are not allowed.

So I'd like to setup OSPF between all the ASA for them to exchange their route within the tunnel. I thought this was automatic when establishing the tunnel, but it isn't.
View 1 Replies View RelatedWhen you configure an ABR to inject a summary route into an area, what are the circumstances under which the ABR will inject the summary? I.e., since it's not a set of specific subnets learned directly from other OSPF routers, does the summary get injected regardless of what's in the routing table of the ABR?
I would imagine this could cause problems in a situation where there is an ABR injecting a large summary into an NSSA that also has a backup path over the Internet (IPsec tunnel or something). For example, if the area 0 routers from which the ABR receives routes went down, the ABR would continue to inject the summary route into the NSSA thus tricking those routers into sending traffic to the ABR rather than over the backup link.
I can't imagine any other way an ABR would decide when it's suitable to inject the summary though.

OK. I think Im going crazy here. Im studying OSPF and I'm working on the DR/BDR election process. I have a topology where three devices (RIDs 1.1.1.1, 2.2.2.2, and 9.9.9.9) are on the same ethernet segment so they need to elect a DR. 9.9.9.9 is a switch and Im using a SVI for the OSPF interface. Van't get the darn thing to show up in the post but here is the topology.URl After OSPF came up, I noticed that router2 was selected as the DR and that switch1 was selected as the BDR. I thought initially that it was a matter of timing and that perhaps router2 just came up first and the slower SVI interface came up second. Shutdown the interfaces, cleared the OSPF process, and set the OSPF router priority on the VLAN interface to 10.

View 12 Replies View RelatedI have a scenario with a Cisco 6506 and a 7206. The 6506 is running BGP and peers with our data center router. The 7206 is a stub router off the 6506 and is used as an edge router for customer T1 circuits. I want to use OSPF between the routers to exchange connected and static routes. The problem I have is that static BGP null routes on the 6506 are overriding the OSPF routes being received from the 7206. Example: The 6506 is advertising a class C network 192.168.1.0/24 to our data center. The 6506 does not utilize the 192.168.1.0/24 network. It is only used on the 7206 for customer T1 circuits and is carved up into /29 subnets. So the 6506 has a static route: ip route 192.168.1.0 255.255.255.0 null 0. Today the routing is accomplished with static routes on the 6506 for the 192.168.1.0 networks on the 7206. Using OSPF the 7206 advertises /29 links back to the 6506, but when I withdraw one of the /29 static routes from the 6506, the /24 null route takes precedence over the more specific /29 routes and the traffic is black-holed on the 6506. how can I get the OSPF routes to look preferable to the /24 null route on the 6506?
