I'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?

We 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 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.
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.
I still want to manitnace it was 2 different OSPFrouting domain.Can I run OSPF with differrent OSPF porcess ID?
I have two core switches - 4506E, and i noticed there are frequent cpu spikes on both of the cores switches. As its spikes intermitendly i couldnt able to anlyze the issue. I need inputs on the following,

2) Troubleshooting techniques to identify the issue.

View 7 Replies View RelatedIn a lab environment, I have a stack of two 3750v2-48ts switches. I upgraded the stack from 15.0(1)SE2 to 15.0(1)SE3 using archive download-sw.
Switch 1 in the stack reloaded and came back with the new image.
Switch 2 appears to be dead. No console out put. When power is applied, the SYST LED blinks 22 times, then stops. I've held in the mode button for up to 60 seconds, held in mode while applying power, removed the stack cables and repeated...there's not a whole lot else I can think of to do at this point.
I would like to confirm if Cisco 3750 and 3750v2 can work in a stack? My Cisco 3750 is working on 12.2(37)se while 3750v2 is working on 12.2(50r)se.
I tried to configure the above on a same stack but seem to have compatibility issue and fail to work.
According to documentation Cisco RPS 675 should have support for Cisco 3750v2 switch(WS-C3750V2-48PS).What kind of cable should be used to connect them?Cisco RPS has 16 pins and 3750v2 has 22 pins.I could not find that type of cable,

I am bringing up a 3750x and a 2911 to replace a 3745 router with switchport module. I was plannng on moving all the VLAN interfaces off the 3745 onto the 3750x and turning up EIGRP. I discoved the 3750 has the LAN Base license, so I can't run eigrp off of it. My question or worry now is, will the LAN base license prevent the switch from doing interface VLAN routing between the different VLAN's configured on it or will I have keep all the VLAN interfaces on the new router and just have a router on a stick setup?
View 4 Replies View RelatedWe are in the process of switching our infrastructure of our routing/firewalls/vpns over to cisco. We are switching our first location and one of the issues I'm struggling with is windows authentication pass-through for internally hosted web pages. Meaning, user inside our network has the 2921 as their default gateway, they try to access a web page that is hosted on the internal network but is secured with windows authentication. In the past, because they are logged into the domain internally, the website authenticates and loads. After switching to the Cisco, it asks for a password even though they are logged in.
Because its the web server that actually authenticates I'm not sure why the router isn't allowing that to happen, but I can't think of anything else that could be causing this behavior.

We are following the ISSU process for upgading a VSS 1440, using the documentation here: URL
After copying image onto both supervisors, when the command:
issu loadversion sup-bootdisk:s72033-adventerprisek9_wan-mz.122-33.SXI.bin is run we get the following error:
% CV [ bootdisk:s72033-advipservicesk9_wan-mz.122-33.SXI.bin ] must be named first in BOOT [ bootdisk:s72033-adventerprisek9_wan-mz.122-33.SXI.bin ]
The advipservice image is the one running, and the adventerprise is the one we are trying to upgrade to.
We are setting up a test lab in our DMZ. The path to the internet is basically like this. Anything past the firewall is irrelevant. For this lab lets assume it is vlan 300.
LAB SW ---> DMZ-SW ---> ASA FW ---> INTERNET
LAB IP Range = 172.16.300.0 /24
GW = 172.16.300.1 (On FW int)
Trunked all the way through.
I have an int vlan set up on the LAB SW. It is being trunked to DMZ SW. DMZ trunks it to ASA FW where there is a failover with a redundant switch.On the ASA the interface 0/2 is a subinterface 0/2.300 being used as the default gateway.
I have DHCP running in a specific range on the LAB SW and do get an ip address when plugged in. I cannot ping the default gateway on the ASA FW.The GW is defined using default-router command for 172.16.300.1 i.e. default-router 172.16.300.1?
We are running ospf on the firewall. There appears to be a pattern with ospf and a similar subnet setup elsewhere. I was wondering based off of this info would configuring ospf for 172.16.300.0/24 allow me to ping the GW from a client on the LAB SW.Secondly. I trunked 300 on the DMZ SW but I didnt add the vlan to the configuration. i.e. conf t <enter> vlan 300 <enter> Does this really matter? Or is having the vlan in the configuration only pertain to access mode on interfaces?
We have 2 sites, each with 2 x 4506 switches which will be connected togther using an etherchannel. The switches will provide access ports for client devices and will be configured with HSRP to provide gateway redundancy. SW1 will be HSRP active.2 metro ethernet links will be installed in each site which will connect back to our HQ sites. OSPF will be used over the backbone to provide resiliency and to allow shortest path routing to each HQ and to prevent traffic over the HQ to HQ link.
The 4506 will be trunked togther with an SVI for providing OSFP adjacency.For the traffic flow from SW2 to HQ2, traffic will hit SW1 and then route back to SW2 and then to HQ2. Is this the best way to do this? Should a second link be connected between switches just for routing or should something like GLBP be used?
I am attempting to filter a specific host(s) from my OSPF routiing table on a ASA 5550 (ABR) using LSA prefix lists. However, when I look at the other routers in that area, I notice that ALL LSA type-3's are being removed (10 hosts are now missing from the routing table). I have verified the filter is working on the ABR, but I can't figure why ALL hosts/routes that were coming into the area are now being filtered instead of the specific one that I want to filter out.
Here is the config on the ABR:
prefix-list pdm_pl_000 seq 10 permit 206.253.180.137/32
!

router ospf 1
network 10.0.0.0 255.255.255.0 area 0

network 10.150.252.0 255.255.255.224 area 10
[code]....
The 206.253.180.137 host is actually coming from Area '3'. Am I doing something that is removing all type-3 LSA's?
