Cisco Switching/Routing :: 4507 Pb To Propagate Ospf Routes To Another Router On

Nov 15, 2011

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.

Cisco Switching/Routing :: 6500 OSPF External Routes Churn

Oct 7, 2012

I am observing some strange behaviour related to the routing table, almost all external routes and some inter-area routes are getting refreshed every 10 seconds.
 
I am getting more than 1000 entries after running 'sh ip route | i 00:00:0', these external routes are being advertised by a neighbor 6500 which redistributing these static routes.
 
Platform is 6500 with SUP-720

Protocols / Routing :: How To Make Sure R11 Is Able To Get OSPF Routes Of All Areas

Oct 19, 2012

How can I make sure R11 is able to get the OSPF routes of all the areas. Make sure area-278 does not receive any ospf routes from other areas as well as from ASBR routes from other areas. At the same tim, area-278 should be able send successfully RIP routes that we receive from R2 to backbone area.

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.

Aug 16, 2012

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)

When I connected via the console and typed "show ip ssh" it came back saying I needed to generate the keys.  Did that  and it starting working again.  The same switch had to turned off and on the other day due to a power down in the server room and when it came back the same thing happened again!!

Cisco Switching/Routing :: 4507 - New Media Net QoS Design

Aug 25, 2012

QoS design problem that I have. I have a client that is deploying new 4507 series switches with SUP6Es. The client will be running lots of voice, streaming video, and video conferencing over the LAN and want to base QoS on Cisco Media net recommendations.
 
I need to design a new QoS policy with focus on the above media services with basic queuing for critical data services. I have read the Media net design guide and the suggested 12-class model will be too complex to start with but I have seen references to start with a 8-class model with the ability to easily migrate to 12-class in the future. The 8-class model meets all of our requirements but I need to understand how this will work with the 4507 queuing model? [URL]

Cisco Switching/Routing :: Err-Discard On X2-10-GB-LRM 3750 And 4507

Jan 19, 2012

we have a core switch 4507RE at the data center and 2 departments that connect to it via 10Gig fiber using X2-LRM modules. Each department  has a 3 switch stack and both locations are identical w.r.t type and setup scenario.the stack comprises of  1 x 3750E and 2 x 3750G . uplink is from X2 port tengig3/0/1 from the 3750E switch.
 
All of a sudden dept B started facing problem , where the ping would break and throughput comes around 6 - 7 mbps   from that dept to the server behind the core switch.   we also noted CRC error on both sides preodically.
 
we replaced the multimode fiber patch cords, re did the splicing , which  stopped the CRC errors to appear.now since morning the uplink port on the 3750E (3/0/1) would suddenly be in "down" state    with (err-disabled) as the status  when i run sh int ten 3/0/1
 
and i can also see CRC errors and input errors on the same interface..   if i do shut / no shut .. the port is up and active again..    but this has happned 3 times today.the core swith side is still OK and no CRC / input / output  errors are seen..
 
now on the 3750E i have  swapped the 10gig module from 3/0/1 to 3/0/2 .  the port is still up but i can see 400 CRC and 500 Input errrors.the module is also OK as i had replaced it with dept 1's module.

Cisco Switching/Routing :: 4507 / Find Out Bandwidth Used On Interface?

Cisco Switching/Routing :: 4507 Not Able To Route Multiple Ip Ranges

Apr 24, 2012

I have this cisco 4507 switch that I need to configure multiple ip ranges on. The problem is that I can only configure two ip ranges on it, one ip range on the management vlan and the other ip range on vlan 2. After I have configured these 2 vlans with different ip ranges, I can route between then and get them to talk to each other, but that is all I can do. If I add another vlan with a different IP range I cannot see it from the switch or get any of the otehr ip ranges to see it.
 
I am doing something dumb because this is a layer 4 device so it should be able to route the ip ranges. I have tried everything just cannot get it to work. I have assigned the IP range directly to the port number and directly to the vlans. Just wont work.
