How do I remove "ip cef accounting non-recursive load-balance-hash" from the config. I'd like to leave the box as I found it. Is it to do with an authority level or something more?
I have configured below SNMP v3 commands in Cisco Router 7206VXR (NPE-G1) . I have tested with all option but it is not working . SNMP server is a SNMPc tool and I have configured user name and piv and authentication credential correctly in both side . Same configurations is working for all Cisco switches but not working for Cisco Router.

I have a 7206 VXR router between a several Mikrotik routers on our backbone. We have the Mikrotiks on both sides of the CIsco 7206VXR setup for MPLS/VPLS. I need to simply setup the 7206 to pass the MPLS/VPLS tagged packets to the next router on the link. We are using OSPF as the routing protocol. I am told by our Mikrotik guy that I just need to enable LDP and VPLS tunnels 4:0 on the 2 gig interfaces on the 7206VXR to let it pass the MPLS/VPLS traffic. It sounds simple but I'm not sure how to do this.
Any commands I need to imput to allow this router to pass this MPLS/VPLS traffic.
i have a 7206 router to be used as a gateway for internet router 7206 inerfaces are connected directly to cisco switch 2960g note that 7600 work only at 1 gega , and cant be used for 10 or 10 . im looking forward to use router 7600 instaed of 7206 i copied the config of 7206 and pased in 7600 but some commands which are under interfaces command was not accepted here is the config which as not accepted in 7600 router
%%%%%%%%%%%%%%%%%%%%%%%% duplex auto speed auto media-type rj45 negotiation auto %%%%%%%%%%%%%%%%%%%%%%%%
note that the 4 lines above was not accpted in 7600. does these commands will affect the new config ?i just want to ask before im trying to apply this config to production network?
When doing some tests with an ASR1K running 3.7.0.S, I noticed that everytimes I reload the router, I got the following error when it loads the configuration: [code]
We currently have two 6509's running in VSS, both switches have a WS-6748-GE module in slot 3. I'm in the processing of removing these modules. I will then be replacing them with a different module type, but I need to know how to remove the old configuration of the previous modules.
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.
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.

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 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 would like to find out what the status is of the Cisco 7204 VXR and 7206 VXR routers?I understand they are EOLife and EOSale.Are they also EOSupport? we planning to upgrade 3 of them in our environment and management requires feedback around this.We thinking of going the ASR1000 route..
One of end costumers is trying to configure IP Accounting on 7206 running version 12.4(4)XD8,The issue we are having is that while the physical interface is up (the sub interface is part of a metro line which is directly connected) we dont see packets being accounted if the destination IP is down.
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?
I have an outside 7206 router that is configured with BGP. Behind that I have an ASA 5520 with a failover. Everytime my primary ISP goes down I have to failover the ASA to restablish a connection to the secondary ISP. When the primary comes back on line I have to fail it over again. I have had Cisco TAC look at the ASA and they didn't see anything misconfigured on the ASA. Doesn't seem to be any problems with the router config either.
I have problem with the WAN Router 7206. It has been reloaded automatically 2 times since yesterday. [code] I have already put this message to the output interpreter and the solution is upgrading to the latest IOS. But, when I search in the Bug Toolkit about SegV problem, this bug status is still "Open". So, how can I upgrade to the latest IOS if the status of this bug is still open?

I have a problem with spurious loss of EIGRP neighbour relationships following the introduction of some IOS 15.1(x) into our network. Here's a rough diagram of the topology in question.
Core sites - summarising out RFC 1918 address space to branch. Core routers are 7206s running 12.4(24)T3
Branch has a fractional Ethernet primary link (4Mbit/s) and 4 private ADSLs using CEF load-balancing (per packet) as a backup link (bandwidth 2Mbit/s to branch, 1Mbit/s to core) These links are on separate routers connected at 100Mbit/s. This topology has been in place for some years without issue.
We've recently started putting in 2900 series routers running IOS 15.1(x) instead of 2811s running 12.4(x) in the 2nd buildings - Routers X and W in the diagram. Following that change we're seeing regular loss of EIGRP neighbours on the ADSL links, errors logged as folllows;
Jan 24 16:30:14.192 UTC: %DUAL-5-NBRCHANGE: EIGRP-IPv4 2: Neighbor 10.121.31.114 (ATM0/0/0.1) is down: retry limit exceededJan 24 16:30:16.852 UTC: %DUAL-5-NBRCHANGE: EIGRP-IPv4 2: Neighbor 10.121.31.114 (ATM0/0/0.1) is up: new adjacency
EIGRP packet debugging indicates that router X is periodically attempting to send an EIGRP update to router B. Router B does not log receipt of this update, consequently does not acknowledge it, router X tries 16 times and tears down the neighbour relationship. It's brought back up a varying but small number of seconds later with the exchange of EIGRP hellos - which seem to be fine throughout.
I've been able to reproduce the problem as described by upgrading a working 2811 running 12.4(13a) to 15.1(3)T with no change in config. Downgrading it back to 12.4 again removes the problem. In fact, when running 12.4 the normal state is for no EIGRP updates to be generated by router X. I can contrive to force an update by configuring static routes on routers W,Y or Z and the updates are exchanged and acknowledged normally between router X and router B. If I shut down router X's LAN connections to router W and the adjacent switch, so router X becomes just a spoke on its ADSL links, the problem does not occur.
We only see the problem on ADSL links right now, I'm unable to confirm yet whether we'd see the same if it were another shaped Ethernet link connecting the 2nd building to the core.
The problem is also apparent when running IOS 15.0(1)M3 on router X.
I've gone through the Bug Report list on CCO and not found anything similar to this. The only documented significant difference in EIGRP defaults I can find between IOS 12.4 and 15.x is that no auto-summary is now default.That's not relevant here though because we explicitly turn it off in IOS 12.4.
So, what I could try to make EIGRP operate seamlessly with older IOSs on 15.x.
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.
We have a Cisco 7206 VXR Router with NPE-G2. As everybody aware that, It has got 3 x Gigabit Ethernet Ports on this. We would like to add Two more Copper Gigabit Ethernet Interfaces. The Configurator does not show any options to add that.Now we have a doubt that, Does this 7206 VXR support how many Copper Gigabit Ethernet Interface ?. There is no clear answer available in the Data Sheets.
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]
We have 2 separate ISP connections with 2 separate routers, during a recent router outage we found that our PIX firewall was not routing to the second default route that I have in the pix configuration. Doing some searches on CCO, I have seen some documents that say that the PIX only supports one default gateway/route. Is this still true, even in version 8 of the PIX software? Is this still true in the newer ASA's? Or will they support multiple default routes?
I'm thinking I'm going to have to setup HSRP on my 7206 Internet routers so the PIX can use one gateway, but wanted to verify before I take the time to set this up.
