Cisco WAN :: 520 IP Addresses Not Be Configured On L2 Links
Apr 18, 2011
I purchased a Cisco 520 and am trying to set it up on my home network.Its ADSL PPPoA for WAN.I am trying to setup 2 LANS. One General Network,One DMZ for webhosting.Now, since this router has 4 ethernet ports, i assumed i did not need VLANS. Except when i try configure an interface with an IP address i get this error: % IP addresses may not be configured on L2 links.Now. Ive looked around on the internet about this error. And it seems that since these interfaces are not Layer 3 interfaces,they need to be associated with VLANS.This would be OK. Except this requires an IP address on an interface on the router! Back to square one.
I'm working on my CCNA. I purchased an old router 2610 with two ethernet ports. I configured the IP addresses on the interfaces and added the default gateway. I configured NAT to go out my ATT DSL router to the internet. With the 2610, I'm able to ping the back end or internal DSL router, but I can't ping the front end, external router, or out to any internet site such as google.
I am testing rogue on wire using 5508 WLC and , I have a dedicated AP configured as rogue detector and configured the switch port where the Rogue detector is connected as trunk. I have plugged in an autonomous AP with open authentication to the same switch so that it can act as a rogue. On the WLC, I can see that Autonomous AP as rogue on Wire. But along with that I am seeing another AP as rogue on wire, even though i have plugged in only one Autonomous AP to the switch.
In setup for old RV042 (V1), when updating / adding Mac addresses, the table is always sorted by IP addresses. But in the new oneRV042 (V3) I have, even with latest firmware 4.2.1.02 the list is random, thereby increasing the chance of user entering DUPLICATE IP addr with diff Mac addr. That will result in conflict.If the firmware sorts the DHCP entries by ip addresses, user would be able to catch duplicate ip errors even if the system does not flag the errors. All Cisco smart engineers can you all get the dhcp entries SORT by ip addresses.
I have configured four E1 links between two locations on my 3745 using WIC-2T cards. At both ends all the serial links are configured as ip unnunmbered fastethernet 0/0 encapsulation ppp OSPF is enabled without CEF I would like to know how load balancing will occur in this scenario?Will all my links be utilised at the same time? Will multiple links be used only when the need (in terms of bandwidth) arises?
I will be configuring all the MEC links on my 6500 VSS chassis tomorrow morning and one thing I am a bit confused about.According to the best practices guide they suggest you configure all etherchannels trunks to be in desirable mode. All the trunks are using LACP active - active right now but that's only to one chassis.Should I change all my MEC etherchannel trunks to desirable mode or just leave them active-active?
I have a customer with a unique configuration. They have two point to point connections - one using a laser link between buildings, and a backup fiber connection running ospf. Issue is when the laser link goes down, there is loss/no forwarding during the reconvergence, causing issues with transffering video feeds.
The regular problem with the LMS topology and WAN Links when you see the branches are disconnected from the HQ BUT in my case the branches are already connected via Layer2 links but unfortunately some intermediate layer2 modem/switch exist in some branches which prevent CDP discovery but you will find both HQ and branch router in the same subnet .
We have a 3845 router at one of our remote sites. We want to connect the router to our central office using the two gigabit ports. One link would be the primary and the other would be the secondary (backup).
The router is running EIGRP and the two ports would have different ip addresses. How can we set up the router to use gi0/0 as the primary port and gi0/1 as the secondary (backup) port? The backup port would only be used if there was congestion on the primary port or if the primary port went down. Is there a way to force the router to make the primary link the best route?

I have two Internet links:ISP1: only Site 2 Site VPNsISP2: only HTTP/HTTPS traffic and incoming remote access VPNs With the security plus license I could correctly configure them both as active at the same time on the same ASA device. Also, I've successfully accomplished the following traffic separation:
Site to Site VPNs goes out through ISP1HTTP/HTTPS traffic goes out through ISP2 The customer request is that, when ISP1 fails the S2S traffic is relayed through ISP2 -> This is working fine, I've already tested!But when ISP1's service is restored and that link is working fine, I want that the S2S VPN traffic gets relayed through it again automatically, which didn't happen. My question is: using SLA will the S2S traffic be relayed through ISP1 again automatically when it's services are restored? If not, which technology should I use to accomplish this?
PS: This is all configured on only 1 ASA 5505 whose license was upgraded.
We have a site to site VPN from one client location to our production center in offshore. At the client side we have a PIX 515 used for the tunnel. Since the client requires a backup VPN over a different ISP we will have to add the ISP to the same PIX and then create the secondary VPN.
how we can acheive two ISP's on one PIX since only two Ethernet ports are availble.
i have two links between two sites in my company. The second one is new and uses IPVPN connection. I am searching a way to use both of them. I don' t want to load balance. I want to send some protocols from the first link and some other from the second. ex. rdp from link 2 and everything else from link 1
can a Cisco 2811 router bundle 2 or 4 ADSL lines ? Reason am asking, we need a device that would be able to bundle 2 or 4 ADSL lines from ISP so that we can you it as backup link in-case the company Internet link does down.
I am using Cisco 861 router for simple network access. I have configured the router correctly with support from few folks of this community but now I am facing a different problem. I am able to ping, tracert and nslookup any internet destination. I am also able to brows secure sites like [URL] but normal URLs like [URL] is not working. I have tried to debug IP TCP Packet Port 80 but it is not showing any results.
I have two sites with identical asa 5505's and each has the dual wan/ISP links and are set for failover using sla monitor tracking. I would like to create a vpn between these two sites that stays active regardless of which ISP link is online. Do I simply make two crytpo map statements10 and a 20 inside each of the asa's to each of the other ASA's STATIC PUBLIC IP's? [code]
I work with the topology view in LMS 4.1. I can see all the links between the differrent switches (N7K, 3750, 3040).I miss only the links between the different N7K's. This links have one special thinks: they are configured as " rate-mode dedicated force" In the N7K cli this interfaces are displayed with the SN too.
sw-bb13# show cdp ne.The links to sw-bb11 and sw-bb21 are not painted in the topoloyview.
We suffer some problems with our remote 2811, that has two WAN links (two different ISP) - we cannot get access to both of WAN at the same time.
At first, the aim was to load balance the traffic between wan links: at first we tried to use OER, but users complained about instable internet connectionthen we tried PBR + NAT Generelly we have just the same scheme as [URL] : dual WAN linksPPTPPPPoE over ADSLequal static routesNAT using route map The problem itself: When both links are up, the 1st WAN is pingable, and the 2nd is notWhen the 1st link goes down the 2nd becomes pingable and accessible and vice versa. When I disabled the CEF, the 1st was still pingable and the 2nd became pingable too, but very unstable
I currently admin a WAN link between two international sites. I have a 2800 at each end. The primary connection between the two sites is 20MB Ethernet PIP MPLS BGP circuit. I also have a pair of T1's in a PPP multilink that I switch over to in the event the primary circuit goes down. I currently am doing the switch over manually. It takes me about 15 minutes to complete it, but I know there must be a way to make this an automatic process.
So a couple questions:
1) Is there a way to create an "enhanced multilink" with the 2 T1's and the Ethernet circuit in the same bundle, in effect giving me 23MBps bandwidth while still being able to maintain connectivity if one of the 3 links goes down? This is my preferred solution
and if 1 is not possible then
2) Is there a way to configure the router so if the Ethernet circuit goes down, all traffic will be automatically directed over the T1's, and then come back to the Ethernet when it's back online?
I have one Cisco router 3845 and one switch 6509, they have two links connected each other via OSPF, I want to have link 1 as high priority, and link 2 as low priority. When the link 1 is down, it can be kicked in to the link 2. How I can implement this setup.
I'm workig with a friend on a project. The setup in place is on yacht that has 4 V-Sats and they are wanting to load balance across all four of these links via a Cisco 2911. My recommendation to him was to just create 4 static default routes to each V-SAT's ip address.
Would this accomplish the goal of load balancing? My concern is that would it actually load balance amongst the 4 links or just choose one and then move other to another link once the initial primary went down? Also would enabling CEF be an option if its a feature the 2911 can do? I've attached the visio to give a better idea.
Who is your Internet Service Provider (ISP)? India- AirtelWhat type of Broadband connection are you using? DSLWhat is the exact Make and Model of your Modem, Router or Modem/Router Please refer to this page with detailed specs: Brand New Beetel 450TC1 Wifi Wireless Modem Router DSL ADSL 2+ BSNL AIRTEL MTNL | eBayWhat is the Name of the Anti-Virus, Security or Firewall Software installed from the problematic computer -Microsoft Security Essential. i have tried uninstalling the antivirus software but no effect!The issue is when i click any link online it displays the following message. Then i go back and do this 3-4 times till its able to load the link.I have had this issue with other browsers. Mostly i use Google chrome. This issue is with wired and wireless connection both.PS: My router is transmitting 2 ssid's at the same time. I am unable to change it.
I have a links wireless system, I am trying to make this a secure connection. I have gon into the property settings and everytime I try to set the security to wpa2 or even wpa it I lose my internet connectivety. I can't get the security key needed.
My router (DIR-655) is all up and working but the only thing thats not working is a link to a picture posted on a web site. If you take the link and paste it in the web browser it displays fine, on a web site that should show the image in a forum, All I get is a white box with a X in it.
I have one cisco 3925 router in my HO and 1905 routers in my Branches (40 Nos). I have 2 MPLS links from deifferent ISP's at 10 locations including HO. I have enable BGP in Both links at HO.In branches, i am using floating static routes.I have 2 kinds of traffic - Application and mail.From Branches i am able to route these 2 traffics through 2 ISP linksBut from HO all my traffics are routing through only one link which select via BGP.I had once routed these two traffic through 2 ISP links using route-map by setting next hop. But if one links goes down, traffic routed through that link using routemap drops.From branch it is shifting to the available link.
I want to configure Reliable static routing with object tracking. I have a cisco 3825 and 3925 router in which the hsrp will be configured . Now these two routers are connected a remote site via three different WAN connectivity as under
1. MPLS 2. LL-1 3. LL-2
The priority of routing is also the same sequence.
Now if the MPLS goes down the remote site should be connected via LL-1. If both the MPLS and LL-1 goes down the remote site should be connected via LL-2.
The LL-1 is terminated on cisco 3825 and LL-2 is terminated on cisco 3925. MPLS is terminated on both cisco 3825 as well as 3925 router.
Whether multiple tracking options are available so that i can achieve the same. Topology diagram is attached.
Does the ASA 5505 will allow the addition of a 2nd external link to its configuration? I know the device is capable of Redundant or Backup ISP Links, but that’s not what I need. I will have two different links for two different purposes. Currently we are using the ASA 5505 just for Internet access, so only the ISP link is connected, very basic configuration. We are planning a connection to a client’s global (MPLS) network and we need to be protected against any traffic coming from that network, ergo we need to use a firewall for connection to that external link.Now with the final configuration the Internet traffic must keep being routed to the ISP link, and some other traffic must be routed to the new external link. Can the ASA 5505 be configured for this scenario?
