Cisco WAN :: 6509 Filtering Out Default Route From Full Internet Routing Table
Sep 12, 2011I have a question about filtering incoming bgp route updates from an internet provider. This provider sends the full internet routing table and default route and on an incoming prefix-filter on the customer switch (C6509-sup720) the default route is only accepted.What happens on the 6509 switch when the BGP peer flaps?Does it need to process all the internet routing updates, and if yes probably it cannot handle all these updates?What happens with the CEF table, will the switch install the routes first?

Feb 26, 2012I have an ASA 5520 connected to a Cisco 6509E, and we're turning up EIGRP between the two. The problem that I'm running into is that there a few static routes (including a 0.0.0.0) on the core that's being redistributed into the EIGRP AS, and I need to block this from being propagated to the ASA. The ASA only has the capability to use an ACL in conjunction with a distribute-list, and I can't find a way to filter the default route (0.0.0.0 /0), while allowing everything else.

Dec 26, 2012We have a six node MPLS network, all nodes route to our main office for a variety of services (email, core, fire shares, Internet, etc). Therefore, the link to our main office is crucial. In the event that the MPLS link to/from our main office becomes unavailable, we would like to establish a secondary route into our main office via virtual private network. Our main office and two branch offices have redundant broadband internet connectionsWe currently have Cisco 1921 routers as our branch routers and a Cisco 2800 as our “core” router at the main office. We also have two SonicWall TZ-200 series firewalls at the two branch locations and a SonicWall NSA-2400 at our main office. The VPN connection seems to work okay.How would I configure my branch routers to advertise and route traffic out the VPN connection in the event that the MPLS leg to/from our main office is down?

Mar 3, 2013I recently added a business cable modem to relieve some of the congestion I was getting on my T1 for our MPLS network. There was an ASA 5510 collecting dust in a closet here and I thought it would be the perfect device for firewalling the traffic coming in from the Cable modem, and handling the routing of our internal MPLS traffic as well. Internet setup was cake. The test laptop I have using the ASA as it's gateway has great internet service but it cannot ping across either of our MPLS networks. I have one MPLS with AT&T and one MPLS with EarthLink. My hope was to use the cable modem as the Default route for all unspecified internet traffic and route our internal MPLS traffic to the cisco 2800 routers that are currently in place for the MPLS. I can ping across the MPLS when I telnet to the ASA, but I cannot ping across the MPLS from the client that is connected to the ASA.

Cisco Switching/Routing :: Configure Routing Between 2800 And 3550
Sep 18, 2012The layer 2 switches are connected to layer 3 Switch via trunks, and routing between layer 2 switch ports with configured SVI's on 3550. All working fine. Now I'm trying to configure routing between 2800 and 3550, I tried connecting both Straight Throught and Crossover cables to the 2800 Fa0/0 and Fa0/1 ports as well as the switchports on 3550
No switchport commands are configured however, the lights do not go on for both straight through or crossover cables. I tried connecting 1750 routers but same result. My goal is to have all the VLANS routed to the internet with configuring NAT translation the router.

Cisco Switching/Routing :: Normal CPU Performance For 2800
Dec 11, 2011Is there any official Cisco reference to describe what is considered to be the highest acceptable production CPU load on 2800 routers? I found the document "Integrated Services Routers G2 - Performance Overview" that states at page 5,Most service providers set their CPU alarms to 60 or 65 percent. Many enterprise customers are comfortable running production networks with CPU around 70 or 75 percent.

Cisco Switching/Routing :: Multicast Filtering Between VLANS (217 / 64 / 80)
Mar 18, 2013I have the need to filter multicast between vlans as described below. PIM Sparse-Mode is being utilized for this multicast network and changing any Vlan to PIM Dense mode is not an option.
- Vlan 217 and Vlan 4 should not be communicating on mcast with any other vlan, including eachother (each vlan isolated).
-Vlan 64 and Vlan 80 are able to communicate witch each other on mcast but not with any other vlans (isolated vlan group).
-All other vlans can communicate mcast freely.
What I've created thus far is below. It does not appear to be the most elegant solution and would be difficult for the administrators to adjust as new requirements come along. Yes, I will be adding the appropriate link-local multicast addresses so as to not break routing and other dependent technologies.
ip access-list ext ANY_CONN
permit ip any any
ip access-list ext MCAST_INTRA_217
permit ip 224.0.0.0 15.255.255.255 133.106.197.32 255.255.224.0

Cisco Switching/Routing :: Best Way To Block Website On 2800
Nov 26, 2012I have a 2800 router and tried so many ways to block the unwanted sites on my office network.Like access list ip based, null0 routing and policy map. Faced issues with below config
1. Creating Access-list. very difficulty to block the sites with https those sites will be opend, and we cant block all the IPs
2. Creating null0 routing. it also a bit deficult the block maximum sites because we can't fiend all IPs for those sites
3. Policy map.. with policy map we can only 1site we can block, but not more than one..
I heard that port based routing or port based access-list are the best ways to stop the websites in my local network..for this one i need to map the site to unsued ports then i need to null rouging or need to create the access-list.

Aug 21, 2012I'm trying to turn off SSH version 1 & 2 to pass PCI compliance. Problem is, I cannot touch the VPN link between the two offices. I'm afraid the PKI certificate used for the VPN will be deleted if i zeroize the RSA key which seems to be the only way to stop the router responding on port 22.
Here is the stuff from the running config related to the crypto map:
crypto isakmp policy 1
encr 3des
authentication pre-share
group 2
[ code].....
I'm only CCNA so I'm not even sure if the certificate or RSA key is being used for the VPN link, but I can't tell from the running config that zeroizing it would be a good idea and not break the VPN. I'm open to other ways of disabling SSH, as we are able to just connect using a console cable. But it looks like denying port 22 with an access-list doesn't even stop the router from responding to the port.

View 4 Replies View RelatedCisco Switching/Routing :: IPv6 Filtering / Policing On 2960 Switch?
Jan 3, 2012Trying to control capacity utilization for guest users connecting to a 2960 switch. No problem for IPv4 users, but IPv6 is giving me fits. What I've found out by trial and error so far implies that there is just enough IPv6 smarts in a WS-C2960-24TT-L running c2960-lanbasek9-mz.150-1.SE to make it impossible to control IPv6 traffic. Blocking IPv6 would be sufficient short term, but MAC filtering on type 0x86DD does not appear to work either. Here are the results I've gotten so far:
What "works":
* Protocol ipv6 or an IPv6 ACL in a class map.
* Using a class map referencing ipv6 protocol or an ipv6 ACL in a policy map.
* IPv4 inbound filters and policing.
* Blocking of IPv4 traffic by a MAC ACL blocking type 0x0800 (IPv4) - note that the docs explicitly state that MAC filters do NOT filter IP traffic, except for on this box on this release they do.
What does not work:
* Applying a policy map referencing a class map referencing protocol ipv6 or an IPv6 ACL to an interface. The service policy is accepted by the parser, but is not inserted into the running configuration.
* "class-default" in a policy map only matches IPv4 traffic, not all other traffic.
* Blocking of IPv6 traffic by a MAC ACL blocking type 0X86DD. No problem applying the access-group to the interface, it just doesn't do anything.
I am aware that this box is not supposed to support IPv6 other than for multicast, but as implemented, this is a hole an abuser could drive a MAC truck through.
My questions:
Is this situation unique to this particular 2960 switch or SW release (I also tried 12.2(58)SE2) or does it afflict all 2960's running LANbase?
Assuming the answers to the first two question are negative, what is the minimum requirement to get working IPv6 policing in an edge switch?
