I have a Cisco 2811 with 8 serial interfaces. Three of them are in multilink1 which is our active connection to AT&T MPLS. I have the other 5 in multilink3 which will be an upgrade to a new MPLS. The two multilinks have different ip addresses. AT&T cannot get the multilnik3 (the new one) to come up. The serial links are clean with no errors. Cisco TAC looked at the config and ran some debugs. Their conclusion was that the far end AT&T router keeps dropping the multilink.Here is a debug of what it does (this shows only one serial interface in the multilink - for testing purposes). [code]
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 my Cisco E4200 set up with a 6rd tunnel. the tunnel seems to work fine for the most part. i can ping ipv6.google.com and get a response.however, i cannot ping the addresses of the IPv6 Tunnel ends from within my network. If i run a ping from outside the network, i can ping the IPv6 address of the server end, however, i cannot ping the E4200's end of the tunnel. is there a specific option that needs to be set? i have allowed ping so that my IPv4 address is pingable, am i missing something for IPv6?
My ISP recently started offering dual stack IPv6. After changing IPv6 from manual tunnel to automatic, none of my devices get an IPv6 address from the ISP. In the troubleshooting page, IPv6 address is also empty. I tried resetting the router but had no difference. We have another router (ASUS RT-53N) and it works fine.The ISP is using PPPoE for IPv4. In RT-53N I choose "IPv6 with DHCP-PD" and Interface "PPP". There're no such options in EA2700 though.
in the "CCIE RS cert guide" author has explained an example about Anycast RP with MSDP. in other part of the chapter, he said that in Anycast RP, the RPs should have the same IP address. but in the example about MSDP, the RPs don't have the same IP. so is this case about Anycast IP or MSDP is different than it? in the other words, should we set the same IP on routers which will be determined as RP, when we use MSDP or we are free to use any IPs on RPs?
My ISP provides IPv6 connectivity in the form of dual stack IPv4/IPv6 with DHCPv6 Prefix Delegation. Using a Cisco IOS-based router I managed to make such a connection by using as a template the Cisco IOS configuration file that my ISP has posted as an example in the following link:
The main point on this configuration is a PPPoE connection with:
I enabled dual stack on my rv042g router but its not recieving ipv6 information from my isp. My isp is Time Warner in Milwaukee. They assure me that they are ipv6 ready and assume the problem is on my end. All they want to do is have me connect one computer up to my modem. What good is that when I have a network that needs service. The router needs to be working not just one pc. My ipv4 is working perfectly. It is obtaining all information automaticly.
I have several RV082 routers in production, most of them on IPv4-only access. I want to roll out IPv6 on all these networks and have set up a test environment for this.I did start with a factory-defaulted router with a fixed public IPv4 address. IPv4 network access does work as expected.With the 6to4 option disabled, the RV082's IPv6 routing table contains several entries for local addresses, but not public ones, as expected. When enabling the 6to4 transition function as described in SBKB article #567, three new entries are created: [code]
With the router's diagnostic ping function I can ping the next 6to4 relay on IPv4 (126.96.36.199) and IPv6 (2002:c058:6301::). But I cannot ping that next hop address given as default route (::c058:6301).The RV does advertise routes with the correct 6to4 prefix on the LAN side, and the clients connected to it configure themselves with appropriate addresses. However I was unable to ping any IPv6 both in the 2002::/16 as well as in the 2000::/15 range from any system on the RV's LAN side. When trying to add a static route which routes the 2000:: prefix with prefix length 15 to next hop 2002:c058:6301:: with metric 1, I keep getting the message "Please input IPv6 Address with correct format!"could there something wrong with this default route? How can it be changed? And what is the problem with the route I am trying to add?
When I attempt to save IPv6 Router Advertisement settings, it fails and displays this cryptic message: Addtionally many of the settings in this dialog are not in the PDF manual. Seems odd - like this portion of the Router Configuration is broken.
Question 1. I have no idea how to route IPv6. My provider has provided me with a subnet. This subnet is for example 1:1:1::/48
The router of the provider is located at 1:1:1::1 and my router should get 1:1:1::2(Cisco router). Every subnet I want to create must be routed by 1:1:1::2, for example if I want to create 1:1:1:1111::/64 it needs to be routerd by 1:1:1::2
How do I configure this on the RV220w?
Question 2. I have the possibility to create vlans on the RV220W. I can configure IPv4 addressen per vlan. Only for IPv6 this is not possible.How do I configure this or when will new software be released to configure this?Or do I have to edit the configuration file?
I noticed that the recently released firmware version 188.8.131.52 for the RV110W router mentions in the release notes that DHCPv6 Prefix Delegation is now supported.
Does that mean that this feature will also be implemented in some future firmware release (if we ever see one) for the RV220W router? This is the method used by most if not all ISPs around the world (e.g. Comcast) for IPv6 and the only one RV220W does not currently support. P.S. As of beta version 184.108.40.206 there is no support for IPv6 Prefix Delegation.
I just spent a number of hours getting a site-to-site VPN tunnel and Cisco Quick Connect client running on my WRVS4400N and RVS400. Turns out the problem was the routers don't route IPv6 properly and it takes precedence over IPv4
After choosing the option "IPv4 and IPV6 Dual-Stack" in Networking > IPv6 > IP Mode, the router's configuration website is not accessible any more using it's IPv4 address or via remote management (WAN IP). However, all other router services (routing, VPN, etc.) are working fine.
At this moment (firmware 220.127.116.11) the router has no IPv6 firewall and therefore when used in a typical dual stack IPv4/IPv6 network it has no protection regarding IPv6 traffic. Hopefully this will be fixed with a firmware update before the World IPv6 Day on the 6th of June 2012.
I have on my ethernet linux box, that is responsible for IPv6. This box is configured as IPv6 gateway from my network and it also sends RA to the network. All devices on ethernet network can work on IPv6 without problem. Clients, that are connected to WiFi, they just receive the RA from this box -> this packet is sended over WRVS4400N to the wifi network. But all other traffic do not pass the WRVS4400N, so the wifi client is not able to ping the IPv6 gateway. There is no problem on IPv4, there the wifi client is able to communicate with any ethernet device.I have tested WRVS4400N setting "ipv4 only". If I switch on "ipv4 and ipv6", than all devices will get some additional IPv6 adresses and the communication from WiFi client to IPv6 router is not working again. How to configure the WRVS4400N to bridge all IPv6 traffic between WiFi and ethernet?
our company backbone is hp 5406, and desktop switches are hp 2510 currently we are working with ipv4.if we want to start use IPV6 for test environment, what’s things we need to enable in our backbone/regular switches.i mean for example if we want to set static IPV6 address for 2 servers and send ping between them, or even make new vlan with IVP6 subnet, and use it like regular vlan but with static ip's(until we got ipv6 dhcp).i have hp 5406 manual for IPV6 but i can't understand what i really need to do for start using IPV6.
I have an unusual deployment scenario which may require the use of a SRP-521W, the scenario is as follows:Temporary Setup:Cisco 857 As the ADSL router until Ethernet Hand-off is installedMultiple IP addresses delivered on the ADSL WAN serviceCisco 857 put into Bridge Mode and connected to SRP-521W WAN portCisco 521W handles the Authentication and RoutingCheck Point Firewall System connected to SRP-521W LAN-1Check Point Firewall has WAN IP 203.XXX.XXX.XXXCisco UC-540W Connected to SRP-521W LAN-2Cisco UC-540W has WAN IP 203.XX.XX.XX If you understand the above scenario, I am curious if this can be done and if so how? I need to keep the networks totaly separate and the only thing they would have in common is the Cisco SRP-521W.It should also be noted that the SRP-521W Is being used because the ADSL service is only temporary whilst the Fibre Build is completed and the carrier provides an Ethernet Hand-Off, then the Internet service will change to this type of presentation and the ADSL router will be relegated to the dark world of loneliness.I have gone through the router and have been playing around with the settings, the issue Is I have nothing in the LAB work up that can allow me to replicate this environment and test it before deployment... So, how to reduce the amount of trail and error I have to encounter to get it to work.
I've put in an SRP-527W for a client and got it working fine. However, it's not connecting using the 5 static IP addresses BT gave me. Where do i input the 5 static IP's on the router that it should connect using?
I work for a company that recently upgraded to a Cisco RVS4000 router in place of a failing D-Link router. I configured the RVS4000 to utilize the same address space as the D-Link previously did (192.168.0.0 Network Address, 255.255.255.0 Subnet Mask, RVS4000 in Gateway Mode with IP Address 192.168.0.1, DHCP Scope from 192.168.0.101 - 200 managed by the RVS4000) before installing it on the network. I powered down the D-Link as well as the cable modem, then all of the workstations in the office. Then, I installed the RVS4000, powered up the cable modem, and once it was ready, powered on the RVS4000.
When devices connect, the RVS4000 is assigning them an IP address in the 192.168.1.0/24 subnet, instead of the 192.168.0.0/24 subnet. I have verified that the RVS4000's GUI is showing the correct settings, but connected devices are not picking up addresses from the correct address pool. In troubleshooting, I went to each workstation, released and renewed their IP addresses, and they picked up addresses in the correct subnet. I thought everything was solved, but the next day, the same problem resurfaced.
I left the DHCP lease time at the defaul value "0", which according to the unit's documentation should correspond to a 24-hour lease period. I suspect this is why I had to renew the clients' IP addresses the next day (today), but I still don't get why the RVS4000 wants to give out addresses in the 192.168.1.0/24 scope. Could this be a holdover from the factory settings?
Additional Information: I did not set up any VLANs on the network and the office only requires one subnet as there are not a lot of devices connected, nor do we need the traffic segragated. The VPN functions of the RVS4000 work fine. Using the QuickVPN utility, I can access the network and resources on the network remotely without issue.
