I have a Nexus 7K router, has 2 ospf process, ospf 1 and ospf2. OSPF1 has several subnets in 10.1.0.0/16 subnet range , OSPF2 has several subnets in 10.2.0.0/16 subnet range. I want to summary OSPF 1 subnets to 10.1.0.0/16 then redistribute to OSPF2. but it doesn't work. [code]

When 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.
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 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.

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 was trying to setup a Nexus (5596 running NX-OS 5.1(3)N2(1)) to use the "ip ospf name-lookup"command that I am using on IOS-based routers. Unfortunately this command does not appear to be supported on NX-OS and I cannot find a replacement.Is this another feature that's left out of NX-OS?
View 4 Replies View RelatedWe 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'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]

View 1 Replies View RelatedOk 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?
[CODE]...
I'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.
I am wondering if I can re-distribute my cabled Internet (part of a LAN) to a separate network via a router?

2) Is it best to configure a vrf context keep-alive
3) just have the management address as the peer ip's.
