Cisco WAN :: 2811 Multilinks Have Different IP Addresses

Feb 5, 2012

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).

Cisco Routers :: RV042 When Updating / Adding Mac Addresses / Table Is Always Sorted By IP Addresses

Oct 8, 2012

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  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.

Linksys Wireless Router :: E4200 Cannot Ping Addresses Of IPv6 Tunnel Ends

Nov 21, 2011

i have my Cisco E4200 set up with a 6rd tunnel. the tunnel seems to work fine for the most part. i can ping 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?

Linksys Wireless Router :: EA2700 IPv6 Dual Stack Doesn't Assign IP Addresses

Feb 5, 2013

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.

Cisco :: Anycast RP With MSDP?

Mar 28, 2012

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?

Cisco Routers :: RV220W - Setup An IPv6 Connection

Jan 25, 2012

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:
interface Dialer46
ipv6 address autoconfig default
ipv6 enable

configure this router according the Cisco IOS configuration file I linked on the top in order to have a working IPv6 connection?

Cisco Routers :: RV042G Not Communicating With Isp For Ipv6 Info?

Jun 27, 2012

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.

Cisco Routers :: RV082 IPv6 Tunneling With 6to4

Apr 28, 2013

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 ( 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?

Cisco Routers :: RV180 IPv6 Error - I18nHTMLMissing

Jun 1, 2013

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.

Cisco Routers :: RV220W - Routing IPv6 Subnet

Feb 27, 2013

I have a few questions regarding IPv6.

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?

Cisco Routers :: RV220W And IPv6 Prefix Delegation

Aug 6, 2012

I noticed that the recently released firmware version 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 there is no support for IPv6 Prefix Delegation.

Cisco Routers :: RV220W - Feature Request - IPv6 Firewall?

Cisco Routers :: WRVS4400N V2 And IPv6 Traffic Bridge Between Wi-Fi And Ethernet?

Jun 9, 2011

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?

Routers / Switches :: IPV6 Implementation In IPV4 Network

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.

Cisco Routers :: SRP-521W With Multiple WAN IP Addresses?

Oct 8, 2011

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.

Cisco Routers :: RVS4000 Not Distributing IP Addresses?

Jan 21, 2013

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 ( Network Address, Subnet Mask, RVS4000 in Gateway Mode with IP Address, DHCP Scope from - 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 subnet, instead of the 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 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.
