Cisco WAN :: 2620XM OSPF Routes Are Not Populating In Ip Route Display

Nov 19, 2011

I have a Cisco 2620XM Router, running ver. 12.2 (7r). I have OSPF connected, however the OSPF routes are not populating in the sh ip route display. The  neighbor relationship is established. The sh ip ospf database does display the other routers running ospf, however only connected (C) and static (S) routes appear.

Cisco WAN :: AGFR01RTR03 / AGFR02RTR03 - Missing Route In OSPF To OSPF Redistribution?

Sep 22, 2011

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

Cisco WAN :: AS 300 Why Redistribution From OSPF To BGP Didn't Advertise O E2 Routes

Jan 9, 2012

I am facing two issues in BGP both the topology and Config files.Because the link between Vail and Telluride runs iBGP, both routers will learn about the networks in AS 300 and AS 400 through native BGP only and both AS's do reach each other. Both routers are also running OSPF with Aspen and BGP routes are redistributed into OSPF domain. Now, Aspen knows about the networks in AS 300 and AS 400. Now suppose the link between Vail and Telluride fails, both AS 300 and AS 400 can't reach each other anymore. The only solution to this is to redistribute OSPF routes to BGP on Vail and Telluride. But when i did this, only routes with "O" learned by Tahoe and Alta. In other words, Tahoe sees only 192.168.1.220, 192.168.1.196 and Alta sees only the same routes. Why the redistribution from OSPF to BGP didn't advertise the O E2 routes?
 
This actually was discussed before but i still can't get it. It is not an actual issue.It is about "Syncronization". I know that we've said many times to turn on Sync. when we do redistribution from BGP to an IGP to make sure that the routes are installed correctly in the IGP routing table. However, as you notice in the configuration, i didn't enable Sync. on Vail and Telluride for a long time and redistribution still works fine.

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 ?

Cisco WAN :: Filtering Outbound Routes In OSPF (Catalyst 4500 IOS XR)

May 5, 2013

We are redistributing routes from BGP to OSPF and we want to filter out some of this routes from the OSPF proccess to be announced to neightbours.We want to announce some networks from ASR#1 to Catalyst. We are redistributing them from BGP to OSPF Area 0. Then, to prevent loops in the topology, these routes have to be filtered out from been redistributed from Area 0 to Area 1 in the Catalyst, so Enterasys appliances don't install those routes through OSPF but to point them out through default route to ASR#2.Is it possible with only one OSPF proccess or we have to separate OSPF in two proccess to redistribute between them?

Cisco WAN :: ME3400 / Injecting Two Default Routes Via Ospf Into Service Provider MPLS?

Jan 24, 2011

We have multiple sites that are linked via MPLS (L3) circuits. We have good size circuits for Internet at two main sites (HQ and QC) and smaller sites come to HQ site to go to internet. We are running ospf (Cisco L3 switches) with service provider (ME3400) at these two main sites and service provider then redistributes routes back into MPLS via BGP and then smaller sites ME3400 learn these routes. i am injecting default routes from HQ and QC, but Telco is only redistributing default from HQ. So large pipe Internet at QC is not being used effeciently. Also if MPLS at HQ fails, then we are told, we need to call Telco and they will make change in their network to now start distributing default from QC.it was my understanding that telco can use BGP communities and advertize one default as prefered and second with higher cost, so that failover can occur automatically. And that they can also set up so that west cost sites use HQ and east cost sites can use QC for going to internet, but they say it is not possible.it the least, can I do something like this at my end for failover for internet, in case MPLS at HQ goes down (soon we will be setting up a point to point VPN tunnel between HQ and QC so that MPLS failure at HQ will trigger advertisement of HQ routes over tunnel via QC into MPLS, so other sites can then come to HQ thru QC over this tunnel. At QC Cisco router (to detect loss of default route from HQ and then start advertizing default from QC)

Cisco :: OSPF Route Propagation Over GRE Tunnel

Oct 16, 2012

Cisco device is neighbored up with a Brocade device via OSPF, and the desired routes are present.This Brocade device is neighbored up with another Brocade device via OSPF over a GRE tunnel. I am not seeing the desired routes present.What kinds of things can I look at to determine the issue? I think I've viewed the OSPF topology database (I'm not that familiar with Brocade) with the show ip ospf routes command and I'm not seeing the desired routes there either.There is no form of route filtering in place. I'll double check, but I do not believe there is any stub routing going on either.

Cisco WAN :: 65199 Redistribute BGP Into OSPF Via Route-map

Nov 20, 2011

Our current router is setup to redistribute our BGP routes into OSPF using the following code:
 
-router ospf 60
-log-adjacency-changes
-redistribute bgp 65199 metric 1500 metric-type 1 subnets
 
I want to filter down the routes so only a set of specific routes is redistributed.. we have done this in the past with EIGRP by doing a route-map / prefix-list to manage the routes passed into EIGRP.My question is I can replicate the metric and the metric-type in the route-map by doing the following: [code] Do I need to be concerned witht the "subnets" command in this design?  What I understand "Subnets".When redistributing routes into OSPF, only routes that are not subnetted are redistributed if the subnets keyword is not specified.  I suspect I need to add it!  So my final code should look like this..

Cisco WAN :: 6509 OSPF Stays In Route Table

Apr 5, 2012

I have an MPLS router that connects to the core network.This router distributes (per route maps) routes from OSPF into BGP and from BGP into OSPF.The OSPF Process conencts a 6509 to the 7206 MPLS router. There are some routes in the OSPF process that I have filtered out of the 6509. They do not show up inthe 6509 at all and this is the only way they can be getting into the 7206.Checking the 6509 database, this route is gone, but it stays in the 7206 until I clear the route manually. The result is the route still gets distributed into MPLS. [code]

One thing to note, there are two possible OSPF paths the route gets into OSPF, one of them, the route is filtered with distribute-list on the 6509, which means it is still in the database, so it is still in the 7206 database, and still get distributed into BGP on the 7206, correct?

Cisco Switching/Routing :: 3750 - How To Distribute Static Route Via OSPF

Mar 26, 2013

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.

Cisco WAN :: 1921 OSPF To Two Routers Sending Default Route From Failover

May 28, 2013

Have a 1921 that has 3 eth connections (1 LAN, and 2 WAN) - I have 2 seperate OSPF processes (2 areas) on the WAN Ints - both upstream WAN's are sending defaults back to the 1921, and the 1921 is sending it's LAN range to them.
 
I have ip ospf cost 150 set on the "failover" WAN connection interface (Both on the 1921 and upstream), but the 1921 is preferring the default route from the "failover"?
 
The default routes are both being received by the 1921, but it's preferring the "failover" Int with the ip ospf cost 150 configured?

Cisco Switching/Routing :: Nexus 7K Ignoring Received OSPF Route?

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

Cisco WAN :: EIGRP 101 - Prefer External Routes Versus Internal Routes?

Apr 8, 2011

Is there a way in EIGRP to prefer external routes versus internal routes. EIGRP always picks up internal routes as long as they are available, no matter if external routes have better metric. Our Scenario is that we have DMVPN hub and spoke topology running EIGRP 101. The Core routers also on EIGRP 101 prefer EIGRP 101 routes. We have the new MPLS network running BGP and redistributing these BGP routes into EIGRP 101. The core routers prefer EIGRP 101 routes (internal) to redistributed BGP (external) routes.

When I enter the address it comes up to the page that says "IE cannot display the webpage".I have treid and both gateways and same result. I am also not able to ping the address from the PC within my LAN.I then went to a different network "not within my LAN" and I am able to access the site without any problem. I have accessed it from my phone also without any problems.I have tried to get to this page from the server and also around 5 other computers within the LAN and the same problem each time.I have security settings very low and also the firewalls are off. I tried on a computer that is connected to my LAN with no luck. I then disconnected that same computer and connected it to a different modem not within the LAN and had no prob getting to the site with the same PC.So I know it must have something to do with my LAN but I have no idea what it could be. I have tried everything I can think of and same result each time.
