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.
View 2 RepliesWe have 2 6513 switches with SUP720/PFC3A and various POE modules and a 6748-GE-TX facing our servers. Additionally, we have a 4Gbps portchannel trunk interconnecting the switches. We have approximately 300 Nortel IP 1140e phones in use between the two switches.For the purpose of call recording, we've attempted to mirror the voice vlan using various approaches and have been met with limited success. We mirrored the VLAN using tx, rx, and both. When using both we appear to get duplicate packets at the destination interface.We seem to lose packets completely going in one direction or another for a given call. Packets are lost before they get to the destination interface?

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.

View 1 Replies View RelatedI 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 have a situation which requires some non best practice stuff to be done. There is a box behind an ASA that has a lot of code that references public DNS names and therefore needs access to itself and a number of other boxes on the same subnet via the public DNS names (that obviously resolve to public IPs). This traffic is dropped on some pretty fundamental ASA characteristics.I know this isn't really ideal, and it should be handled by DNS nstead, but I'm in somewhat of a bind and need to know if the ASA can allow this traffic.I figure I could match the traffic and exempt it from state-checking and that would probably work, but it's not a very graceful solution.
View 2 Replies View RelatedI 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 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.

A web server has a private address of 172.168.50.10 and it is being translated to the internet with serial's interface 68.32.x.x (public ip) with static nat. Clients in the internet type the public address to access the web server.
b)Problem: clients inside the LANs cannot access the web server by typing the public address, they use the server's private address instead, this create a problem with DNS static entries in the HOSTS file in the OS. It is a test server and is only available to authenticated users (lock and key ACLs), so no need to make a real DNS record. The entry in the HOSTS file points to the public address.

Here is a snippet from "show ip cache flow", from a border router of our network; [code] To clarify, Gi0/3 faces our customers, Fa1/0 faces a transit provider. These results have come from configuring "ip flow egress" on Fa1/0, facing the transit provider. 1.2.3.4 is a static IP we have assigned a customer. I know this customer has a firewall terminating this connection so I want to understand the cache flow results on this route. Why is the destination address an RFC1918 address? Is it possible that the customers firewall is trying to connect to these addresses, the flow gets as far as this border router, and drops? I assume that to be false, and only successfully initiated flows are recorded?
Also, looking at those figures it's IP protocol 0x11 which is UDP (17) and source port 62023 to destination port 161. 161 is SNMP? Without asking the customer what they are doing I suppose I can never know at that level, but I'm really more interested in why these flows are showing at all, when 192.168.1.0/24 isn't in this routers FIB?
I am trying to perform destination NAT through a VPN tunnel.my scenario traffic coming from 172.29.11.135 needs to connect to address 192.168.1.1 from the source device traffic will have a source IP address of 172.29.11.135 destination will be 172.30.14.1 traffic will hit the asa 5510 and the traffic source will stay as 172.29.11.135 but the destination needs to change to 192.168.1.1.
I have tried the different types of NAT but been unsucessful with all. My VPN tunnel will connect if the destination address does not change (NAT Exemption used). This scenario is even possible on Cisco devices. I have seen discussion that NAT the source address but not the destination address.
example config
access-list FROM_INTERNET extended permit esp any any
access-list FROM_INTERNET extended permit ah any any
access-list FROM_INTERNET extended permit gre any any
access-list FROM_INSIDE extended permit ip host 172.29.11.135 host 172.30.14.1
access-list VPN-TUNNEL extended permit ip host 172.29.11.135 host 192.168.1.1
**I have left other config statements off as the NAT config used previous has not worked and the VPN tunnel does build when using NAT exempt.
**All ACL have been applied in the inbound direction on the respective interfaces. Two static routes have been applied to the FW directing inside traffic inbound and all unknown traffic outbound. I have not defined a specific static roule for the VPN traffic allowing the default static to perform that function.
i have a situation where i have a deployed asa5505 running 8.4.1.The client has an existing mail server that is located on their lan and has Port Nat's configured for the normal mail ports, 25,110,993,587 etc.
This works fine for mail inbound and for any user popping mail off the server externally or visiting the webmail interface from outside the network.However when users inside the LAN try to connect through the ASA back inbound to the IP on the External Interface of the ASA they are unable to do so.
One solution i came up with is Split DNS. and well this works it rely's on the users not changing their dns servers.I was wondering if it's possible to do some sort of NAT that rewrites traffic destined for the above ports on the external IP to the Internal LAN Ip instead.
I have several Cisco switches connecting our network. Switch N connects to the gateway, Switches Y & Z connect to some hosts. Switch N connects to Y and Y connects to Z. Assume our gateway IP is a Class B address with a netmask of 255.255.254.0 and all the hosts attached on switches Y & Z have static IP addresses assigned to them. This gateway connects to the internet.In addition to this IP address, some of the hosts also have a second IP address assigned to the same NIC. This IP is Class A (10.0.###.###) and have a netmask of 255.255.0.0 A second gateway address is not defined.
The hosts that have 2 IP's bound to their nic, use the 10. address to communicate with each other. (Programs running on the hosts are specifically configured to use 10. address).I have several questions regarding this setup:
1) Assume Host has only 1 IP (Class B) - if the destination is on the same network, does the host system send the packet to the gateway first to find the destination on the network or does the host send a "where are u" packet to the broadcast address to find the destination?
2) Assume Host as 2 IPs (Class A & B) - if the destination is a 10. address, how does the host go about finding it?
Since there is no Gateway defined for the Class A address, does the host simply send out a packet to the broadcast address for the Class A network? or does it go to the gateway defined in the Class B network as it was defined first (i'm assuming primary connection)
3) Assume Switch N's connection to Switch Y is disabled - how will this affect communication between hosts on Switches Y & Z that have a 10. IP trying to share data with each other, using the 10. Address. If the answer is this should not affect it, what additional circumstances are required that may cause the systems with a 10. address to be unable to communicate when the connection from Switch Y to N is terminated?]
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.
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 are running OSPF on this router
