Cisco WAN :: 6506 / 7206 - OSPF And BGP On Same Router?
Jan 18, 2012
I have a scenario with a Cisco 6506 and a 7206. The 6506 is running BGP and peers with our data center router. The 7206 is a stub router off the 6506 and is used as an edge router for customer T1 circuits. I want to use OSPF between the routers to exchange connected and static routes. The problem I have is that static BGP null routes on the 6506 are overriding the OSPF routes being received from the 7206. Example: The 6506 is advertising a class C network 192.168.1.0/24 to our data center. The 6506 does not utilize the 192.168.1.0/24 network. It is only used on the 7206 for customer T1 circuits and is carved up into /29 subnets. So the 6506 has a static route: ip route 192.168.1.0 255.255.255.0 null 0. Today the routing is accomplished with static routes on the 6506 for the 192.168.1.0 networks on the 7206. Using OSPF the 7206 advertises /29 links back to the 6506, but when I withdraw one of the /29 static routes from the 6506, the /24 null route takes precedence over the more specific /29 routes and the traffic is black-holed on the 6506. how can I get the OSPF routes to look preferable to the /24 null route on the 6506?
I want to configure multilink between two Cisco 7206 routers POS interfacesafter configuring both sides.Router 1interface Multilink5 ip address. [code]. I can see both sides through show cdp, also ospf process goes to FULL stateBut traffic is not flow between interfaces, and i can not even ping router's own ip address.When i delete network statement from ospf process, i can ping router's own interface and both routers can ping each other.
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).
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
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 need to upload IOS c7200-advipservicesk9-mz.124-15.T16.binin 7206 NPE 400 router , As per cisco recommendation router should have DRAM : 256 MB ; Flash : 64I think my router contain only DRAM= 128 MB but not sure.
how much DRAM & Flash it contains.

We have a router (7206) which connected to client device in /30 IP segment, but this device is a switch which connected to many more devices. Doing packet capture on our router interface unravel many ARP requests whcih comes from the client switch. Is there any feature or command which we can stop this?
We have a 7206 router which acts as a MPLS Hub router for around 100+ remote locations. Bandwidh at mpls hub(terminated on this router) is 50 Mbps.
We have noticed that Memory utilization in this router gradually increases and when it reaches 100% this router hangs. It happence in frequesncy of 10 days and we have to restart the router when memory is 100%.
CPU utilization is normal i.e below 20%, WAN bandwidth will never cross 30mbps.
We could not able to upload an IOS for 7206 router with NPE-150 via xmodem as there was no image available in flash it is in rommon mode. But same can be done in 1841. So how to upload an image in flah for 7206 via xmodem.Where the IOS will be stored in 7206, wethet in flash or NPE. If it's in flash what for NPE used other than for routing engine capabilities.
i have a cisco router 7206 ,when i create subinterface with ip , the router hangs , and all interfaces are down ,i just remove interface gi0/1 and plug it again, what is the relaiton between subinterfaces and hanging routers> the problem occurred when i configured sub-interface on GI0/2. [code]
I have a Cisco 7206-CH router and the power supply have been stopped working. I am very confused if the new " PWR-7200-ACE= " power supply can be used with this model which have been announced as end of sale and support from 2007.
Whenever I want to turn off the ip cache flow and enter command "no ip flow egress" on a router interface, the router will self reboot and returned with the error message - System returned to ROM by bus error at PC message in the show version ouput.
I tried on two different routers below here and both also undergoing a cold restart when I key in the command "no ip flow egress" on the said interface
1) Cisco 7206 running IOS 12.4(1c)
interface GigabitEthernet0/1 ip address 10.20.10.2 255.255.255.0 ip flow egress duplex auto speed auto end
when I key in "no ip flow egress" under int gi0/1 and the router self restarted and return the message Router uptime is 3 minutes System returned to ROM by bus error at PC 0x606D48FC,address 0x0
2) Cisco 3845 running IOS 12.4(3e)
interface GigabitEthernet0/0 ip address 10.20.20.2 255.255.255.0 ip nbar protocol-discovery ip flow egress duplex auto speed auto end
when I key in "no ip flow egress" under int gi0/0 and the router self restarted and return the message
Router uptime is 3 minutes System returned to ROM by bus error at PC 0x6007EBE0, address 0x0
I have configured policies to shape the traffic on the interface of cisco 7206 router. Now my managemet wants to configure these policies on time based ie policy should be applicable during specified time period onle. Is it possible? if yes how to configure it?
I am running IPv4 with OSPFv2 currently. However, I planed to deploy IPv6 in my network. Is it possible to deploy V6 with OSPFv3 without affecting current network traffic in V4?
Application is that need to configure the VOIP with the existing Frame relay network ,where VOFR command is not shown in the router when type yhe command router config#dial-peer voice 123 need vofr On the 3945 router where in the router it is not accepting the above command,
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]
but when i configure the poller i believe the data i mixed up somehow. I for example i don't get all neighbor in the ospfNbrState. i tried with snmp context configuration but i am not sure if this right what i did.
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.
I have two 7206 VXR routers with the VPN Service Adapter either side of a leased line (i.e. no provider between, pure layer two connectivity)A requirement is that traffic traversing the link is encrypted so I've configured an IPSec VPN between the two endpoints.During load testing we noticed a very severe performance hit when the VPN was enabled, disabling it again saw we were able to use almost 100% of the 1000Mbs line. The performance hit looks to be due to the increased MTU size when using IPSec, possible due to fragmentation.
I've read that the 7206 VXR can support 980Mbs (or there abouts) of throughput using AES providing the MTU size is 1400.Configuring this manually on each server in each data centre isn't feasible.As the link is effectively a point to point and we have control over the MTU size between the two routers, what options are available to increase the performance when the VPN is enabled?
I am attaching my current network topology, My problem is that i am having mpls & p2p link terminated on the 7206 router left side of diagram. now my problem is if i apply PBR on this 7206 router & tracer any host which are on right side of the diagram, it drops on IP 10.1.1.1..ideally it should go to my Core switch on right of the diagram.
I am having a Cisco 7406 VXR router. I want to know what is the max. MPLS link capacity that can be terminated on the link? We are planning to upgrade the MPLS link to 450 Mb..so was just wondering whether 7206 will support or not..
I have a problem in understanding how LLQ is implemented in different platforms of Cisco.QoS should kick in only when there is a congestion in the link irrespective of queueing / scheduling (LLQ and CBWFQ).But in certain platforms like GSR and IOS-XR, LLQ is confiugred only with priority and police command not with "prioirity percent <value>" command. In priority and police command since policer is used, LLQ is always on even there is no period of congestion. Of course with police you can re-mark the exceed traffic to different marking but thats not the requirement in my case.
In platforms like 7206, LLQ is configured with "prioirty percent <value>" which works ideally only when there is a period of congestion. When there is no congestion, LLQ class can use scanvenge other classes as well.Would like to know is there any specific reason why there is a difference in the implentation of LLQ between different platforms of Cisco.
We want to configure RTR in our network ,having a Cisco 6506 core Switch & 50 Cisco 2960 Switches. As per the ios on the 6506 the rtr command is supported not the ip sla , so we want to configure it on it.
The RTR configuration on the Source device (Cisco 6506 Sw) can be done through the below commands :
1) enable 2) configure terminal 3) rtr <Entry number> 4) type echo protocol ipIcmpEcho <Hostname or A.B.C.D IP address or hostname> source-ipaddr < IP address > 5) frequency seconds 6) exit 7) rtr schedule entry-number [life {forever | seconds}] [start-time {hh:mm[:ss] [month day | day month] | pending | now | afterhh:mm:ss] [ageout seconds] [recurring] 8) exit
RTR configuration on the target devices (Cisco 2950 SW )will be :
2) And for every Cisco 2950 Switch , i have to create seprate rtr entry on Cisco 6506 Sw for example for 50 target device i have to create 50 entries on source device 6506?
i did in past a lot of L2TP connection between two end point. in this case ans with 2911 series with ios 15 and DATA license Activated. the l2tp session does not establishe between a this 2911 and 7209. Attached is topology file and bellow the configuration of both router.
I have a lot of cisco 7206 vxr deviceses. I have a high cpu problem.I have a 7206 vxr g2. I used to use ebgp for three upstream carrier. I used to bgp full route table method. I have about 800 Mbps active traffics and behing the router about 1600 active customers.
How can I trouble shoot this high cpu problem?

I upgraded the IOS on 6506E, SUP 720-10GE, non-redundant, to a new one, rebooted OK. Switch seems to work fine but "show bootvar" shows the previous IOS name instead of the new one: s72033-advipservicesk9_wan-mz.122-33.SXJ3.bin.Removed the old IOS name on "boot var", gave it new IOS name, "show bootvar" now has correct new IOS name, write mem again and reloaded switch.It booted up OK but "show bootvar" still has the old IOS: "s72033-ipbasek9-mz.122-33.SXI2a.bin".According to IOS upgrade procedure, after all the upgrade IOS steps done, then just "write mem" then the "bootvar: will have the new IOS name, but on my switch it is always has the old IOS name ? How can I set the bootvar to new IOS name?
