Cisco Switching/Routing :: 867VAE-K9 Is Missing OSPF?
Dec 12, 2012
I have a 867VAE-K9. On feature navigator it is listed as supporting OSPF. However when I go into config mode and type "router ?" BGP is there, but OSPF is not. Also, under my tunnel interfaces there is no support for any OSPF commands such as "ip ospf cost" etc. I'm in the process of raising a TAC. I have tried five or six different versions of IOS code that is available for this device, in each, we never see OSPF listed but sometimes see "router odr" or "router lisp"...

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).
AGDC01RTR01 --- AGDC02RTR01 (OSPF 1000 ABRs)

AGFR01RTR03 --- AGFR02RTR03 (OSPF 1000 / 53 ASBRs)
Let's focus on AGDC01RTR01 with a specific entry here (IP subnet is fake) :
Routing entry for 1.1.1.0/25
Known via "ospf 1000", distance 110, metric 300, type inter area
Last update from 10.2.244.76 on GigabitEthernet5/1, 1d03h ago
Routing Descriptor Blocks:
* 10.2.244.76, from 10.2.1.249, 1d03h ago, via GigabitEthernet5/1
Route metric is 300, traffic share count is 1

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 10.150.10.0 255.255.255.0 area 10
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?

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.

Does 800 series routers support OSPF or EIGRP? Command for EIGRP is available but when you try to run it, you get that "protocol is not available in the image". Is there a specific image that I can get that will support either of these two on a Cisco 851 or 861?

I am in a doubt if the 3560-12-PC-S supports OSPF. Datasheet says we need IP Services image. But 3560-12PC doesn’t have the option with IP Services. Then I havigate to [URL] how?
So, any clues whether or not this box can run OSPF?

We have an existing network with a core 6500 as a VSS connecting 4 buildings with 4500 chassis under which number of L2 switches are connected. Currunlty we are using RSTP in ring for redundancy but we want to use OSPF in LAN for faster conversion.All the VLAN's are created on 6500.

I am beginning to implement OSPF into the network I work on. I have a network which consists of multiple 4500, 6500 series routers and 3560s. Each switch has its own set of VLANs. In other words VLAN X on one switch is not the same as VLAN X on another switch. I had envisioned connecting each switch via trunk links and then routing via the loopback addresses on each device. That didn't work. Then I created a VLAN 100 on each switch. Each one was configured with an IP in the same subnet range (10.3.0.1 and 10.3.0.2). I added these addresses to the OSPF process in area 0. It worked. However, this is not desired. I have not seen many examples of 4500 layer 3 switches configured with OSPF. The examples I have seen show the interfaces configured with IPs.

I 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.

I have a problem with ME-3600x running two ospf processes. Proc1 is WAN and PRoc2 is LAN. I am redistributing routes into both directions. After a WAN outage , certain wan routes did not get redistributed into the LAN process. I had to do a clear ip route to fix the problem. Has anynoe seen such a scenario with ME-3600x or any other switch/router

I manage a small/medium sized campus network consisting of 4 Cisco 6500 series chassis (each with SUP720's) and a couple hundred Cisco 3550/3560/2960 edge switches. We recently completed a new leg of fiber that will make a completed loop between all of the 6500's .... before I make the pyhsical connection I need to figure out my OSPF entries on each 6500 switch.

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?

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?

I'm working on a little OSPF setup in my lab and having a problem pinging out to the internet.I have a setup with (3) 3550's running ip routing. I'm configuring OSPF but I can't ping the internet from any L3 switch except the switch with the actual uplink to the internet.[code] From SW2 and SW3, I can ping SW1 on all IPs (192.168.1.90, 10.10.10.1, 10.10.10.5) but I can't ping 192.168.1.1 which is my gateway to the internet.

our backbone (6509) is connected to atm backbone (nortel passport) those are connected through giga Ethernet interface and running ospf in area 0. One week ago we lost the ip connectivity between those backbones, the interfaces were in up but the neighbor relation fail and it was kept in LOADING STATE, according we the logs the neighbor relation fail because a BAD LSA was received (error messages %OSPF-4-ERRRCV:Bad LSU adv and %OSPF-4-BADLSATYPE:Invalid lsa:Bad LSA chksum Type 5 were received during the outage)We check in cisco and this is quite normal behavior if we receive a bad LSA but the customer is asking why we have the same error message for long time and we didn't lost the neighbor relationship.
how many bad lsa we can receive before to lost the neighbor relationship.We receive two errors messages for bag lsa.. [code]

Configuring OSPF on a catalyst 3560G Switch to connect to our building next door by way of fiber. The other two switches in the other building are running OSPF, I am trying to connect to the other building and access a server which is on a switch running OSPF. I am trying to configure the switch here to run OSPF and be able to see the neighbor, but currently can't although I've identified the networks. Maybe I'm missing something, I've followed the instructions but something is not right.

We have a 14 offfice MPLS network. All offices have Cisco 3750s running OSPF which replicate route tables via our providers BGP peers. I am introducing a new network in our SF office which is not directly connected so in SF we have a static route "ip route 172.16.20.0 255.255.255.0 192.168.100.1. I want our other offices to learn this route route via OSPF so that they know how to get to the new network. My problem is that of course remote sites do not see our static routes and i have tried to add this via ospf but the switch will not propagate this route because it is not directly connected to the switch in SF.

i'd like to configure OSPF on a Catalyst 6503 IOS 12.2.17.i habe an Gi1/9 with the ip address 192.168.97.30/24 and a VLAN 19 with the IP Address 192.168.19.0/24.I configured OSPF like this
router ospf 1
network 192.168.97.0 0.0.0.255 area 10.5.0.0
network 192.168.19.0 0.0.0.255 area 10.5.0.0
on the ospf peer is see that the adjaceny is established but i don't get the routes for the 192.168.19.0 network i checked the ip ospf interface vlan 19; i got ospf is not enabled on the interface then i tried to configure
int vlan 19
ip ospf 1 area 10.5.0.0
but it does not access ip ospf 1

On a 4507 v12.2(20)EW, the connected subnets which are declared in the ospf instance are not propagated to the MPLS carrier router.Only the static routes which are redistributed in the ospf instance are propagated to the MPLS carrier router.

We have our network setup as displayed in the attached. We have 2 HQ offices and 1 branch office. The branch office needs to connect to resources located at both HQs but taking the most effecient path. We have ethernet circuits connecting from each HQ to 2 x Cisco 3560 switches in the branch. HSRP has been configured on the 3560 switches with SW1 as active and SW2 as standby. OSFP has been configured in a single area 0 and the path cost on the link between HQs has been increase to allow 3560 SW1 to route to HQ1 directly and HQ2 via 3560 SW2.The 3560s are connected with a trunk with a L3 SVI for OSPF. This seems to work ok but I have noticed that the branch could become transit if the HQ1 to HQ2 link breaks. How can this be avoided? I realise that if we configure the branch subnets and SW1 to SW2 link in a stub area (area1) then all traffic will route from SW1 to HQ1 and will never share over SW2. I'm assuming that this is because OSPF chooses inter-area routes over intra-area.

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?.

I am having a problem reaching a soho linksys e1000 router through a second hop cisco 2900 router.Here is a brief topology of the network: I am using OSPF area 100 for all networks except for
192.168.2.0 on R1 to E1000 which is RIPv2
R1 directly connects to R2 with a point-to-point serial on network 192.168.12.0 /30 with ip 192.168.1.13
R1 directly connects to a a switchport using network 192.168.2.0 /24 with ip 192.168.1.75
R3 directly connects to a switchport using network 192.168.1.128.0 /25 with ip 192.168.1.129
R3 directly connects to a different cisco router using ethernet on network 192.168.1.0 with ip 192.168.1.1
E1000 directly connects to a switchport using network 192.168.2.0 /24 with ip 192.168.2.1
The switch has a vlan ip on 192.168.1.128 /25?I can ping from R1 to E1000?I can ping from R3 to R1 192.168.2.75? I can't ping from R3 to E1000 192.168.2.1?show ip route on R2 indicates that network 192.168.2.0 is reachable via the serial connection on 192.168.1.12?I have redistributed rip to ospf area 100 and OSPF to RIP on R1?I am wondering why R1 can reach E1000 on network 192.168.2.0, and why R3 can reach R1s 192.168.2.0 newtork, but R3 can't reach the E1000.There is an R2 router than can reach R1 and also cannot reach E1000, but I assume it's for the same reasons R3 can't, so I've omitted the remainder of that topology for this question.

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.

I'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]
