Cisco Switching/Routing :: 841 - Two Routers On Same LAN?
Jul 18, 2012
I am planning to add a second router to my network. I currently have a Cisco 841 which is running great no issues no down time solid.My only issue with the 841 is that I can not VPN into my network remotely using 1. Native VPN client on Windows based computers. Windows 7 , Vista and XP. 2. Ipad's and Iphones also cannot VPN in. Only way to VPN is from the Cisco client on the Windows platform. No such app exists for the Ipad or Iphone.
So I am looking into getting a Cisco ASA5505 and add it to my network.I could then remove the VPN services from my 841 and use the ASA5505 for all VPN traffic.
Questions.
1. Would I need to have another static ip address?
2. Can I just forward all VPN traffic thru the 841 to the ASA5505?
ip nat inside source static tcp 192.168.69.9 1792 interface FastEthernet4 1792
ip nat inside source static tcp 192.168.69.9 1723 interface FastEthernet4 1723
ip nat inside source static udp 192.168.69.9 1701 interface FastEthernet4 1701
ip nat inside source static udp 192.168.69.9 500 interface FastEthernet4 500
192.168.69.9 would be the new ASA5505 router?Would be nice if the 841 would work using PPTP but I believe it only supports IPsec

I have 3 877 ADSL routers for internet connectivity. I recently installed a FW behind them and would like to use the Ciscos as load balance in order to get better utilization from my 3 internet links.
1) the 3 routers are on DHCP from the ISP on the WAN side.
2) the 3 ciscos are on the same class C subnet on the LAN side: 10.201.1.252, 10.201.1.253 and 10.201.1.254

I've set up a simple lab network of two cisco routers 2611XM and to each router I've attached a computer (host). I have set up a dhcp ip addresses for each host. I've set up a correct routing as well on each router. There are 3 networks: 192.168.1.0/24 192.168.2.0/24 192.168.3.0/24 The first network between the first host and first router, second is between two routers and third is between the second router and second host. If I use first host (192.168.1.20) I can ping to any ip address (192.168.1.1 (router 1), 192.168.2.1 (router 1), 192.168.2.2 (router 2), 192.168.3.1 (router 2)) except the second host ip address which is 192.168.3.20. When I sit on the second host (192.168.3.20) i can ping to 192.168.1.1 (router 1), 192.168.2.1 (router 1), 192.168.2.2 (router 2), 192.168.3.1 (router 2) but i can't ping to the first host which is 192.168.1.20. I've even tried with attaching a switch to a router and assign it an ip address of 192.168.1.3 and the ping was echoing to it.

My book says there are two types of firewall supported on cisci ios routers:
Classic cisco ios firewall
Zone-based policy firewall.
zone-based policy firewall with configurations ?
What kind of firewall is supported on Cisco PIX 515E ? Is it Classic CIsco ios firewall or Zone-based policy firewall ?

Scenario: Two buildings connected with a private leased fiber line, so it does operate as a LAN. There are several subnets and everyone at both buildings needs to be able to access all subnets. However the physical machines on those subnets are building specific:
-Building 1: 10.2.0.0/24 (vlan20), 10.4.0.0/24 (vlan40), Internet connection
-Building 2: 10.1.0.0/24 (vlan10), 10.3.0.0/24 (vlan30)
The majority of the traffic between the subnets is specific to the buildings as well (i.e. most of the traffic is between 10.1 and 10.3 or 10.2 and 10.4).
Currently I have a Catalyst 3560 at Building 1 operating as the single "core" L3 router (and then a variety of switches connected to that). I have another 3560 at Building 2 that I'd like to turn in to the "master" L3 router for the two subnets primarily used by Building 2. In other words, make it so traffic from 10.1 to 10.3 doesn't have to run to building 1 just to get back to building 2.
I've got a basic knowledge of adding VLANs, VLAN interfaces and a static routes. The part that I'm getting confused on is that the Building 1 core router needs to make its default route to the firewall (and on to the internet) but "know" that traffic on vlans 10 and 30 gets sent across the fiber line to the other router. So I'm assuming this gets done with some combination of vlan definitions, vlan interfaces and static ip routes on each router.

Does the 2901 have etherchannel capabilities? If so, how to configure it? I mean, I can type "show etherchannel 1" in it, so I would assume if I can show it, I better be able to configure it, right?What about the 2911?

I was assigned a task to configure an SG300-28P to have 3 different vlans.Now on VLAN1 their will be only one device configured with static IP 192.168.0.230,On the other 2 VLANS there will be a separate router connected on each one of them and will also act as a DHCP server.

we are moving to different providers. We currently have multiple sites that have MLP bundles going to our current provider. We are trying to limit our network disruptions by creating a new MLP bundle group and connect it to the new provider, but are having no luck. In a GNS3 lab I have setup I am able to keep my existing MLP bundle up/up over the current provider network. When I attempt to bring up a new MLP group to the other provider my MLP does not come up and keeps going up/up then down/down and shows inactive. Is it possible to have one MLP group go to current vendor router, then create another MLP group and go to the other router?

I have 2 PE routers connected to each other via 2960S and 3750 (non-metro) switches:
[PE1] -- [2960S] -- [3750] -- [2960S] -- [PE2]
I will be sending voice and data traffic between the two and my voice traffic will be marked DSCP EF & EXP 5.
Since the 2960's and 3750's can't match on the EXP bits, I am wondering if the "mls qos trust dscp" command still works. Is the 2960/3750 able to match on DSCP even though there's an MPLS header on top of the IP packet?
I'd like to avoid having to tag my VLAN traffic on the PE and rely on COS to achieve QoS in this case.

we have a pair of 7609 routers working in Active Standby mode. The version of routers are :- Cisco IOS Software, c7600rsp72043_rp Software (c7600rsp72043_rp-ADVIPSERVICESK9-M), Version 12.2(33)SRD4, RELEASE SOFTWARE (fc2)
Quiet frequently we are getting High CPU load problems on our router and this load comes down below 10 % automatically.
I am attaching the Show tech support for your kind consideration.
Similar issue was reported yesterday as well for which i have attached SH tech suppot.

I have 2 ASA5510's acting as routers/firewalls, setup on a LAN, each one pointing to a different gateway (different ISPs), and the exact same VLANs set up as sub-interfaces on each of these. Both act as DHCP relays to a Windows Server 2008 DHCP server. All the Trunking has been setup and works. When I Untag a switch port, and point it to whichever gateway?

While I managed to connect to each router individually, I decided it was time to connect the routers together via serial; as I don't have any serial cables and need to buy some, what serial cables I need, as well as to ask whether I have the right cards in my router(s) that will allow me to do so.
I bought 3 1841 routers, and all have a 1 port serial WAN Interface Card (WIC 1-T); one router has 2 of these, and one router has a WIC-1B-S/T .. My question is, can I connect the routers with a serial cable via WIC 1-T, or do I need a 2-T

I have 1841, 2800 and 3800 routers and need to do IOS upgrade to all of them. Existing routers do not have enough flash to hold 2 IOS images.if the router has 12.4.13r ROM IOS, will I be able to boot the ISR router via Cisco brand USB? That means in case something goes wrong while I am uploading new IOS to the router via WAN and something wrong, now router in ROMMON mode. If a local site person has a Cisco USB with an IOS in it, can he just stick it to the router and reboot the router and router will go out of rommon and go into normal mode? After it is working, then I can put the running IOS onto the exisitng CF card so now I can remove the USB and the CF card has a good IOS and reboot the router again.I am just trying to find a safe way to upgrade the site when they don't have big enough flash to hold 2 IOS at the same time. The local person is not technical so asking him to setup tftp server and put the IOS in the computer and so I can do tftpdnld while in rommon mode to grab the IOS from his tftp will be difficult to have the local person to set it up.
If ISR can boot off of the IOS in USB only, then I assume the requiremetn is the ROM IOS needs to be 12.4.13r. Then what is a safe way to upgrade the ROM IOS to this then? I never upgrade ROM IOS before so don't know what kind of problem I may run into and whether it's higher risk to upgrade this than upgrading the regular ios? If it is, then all my routers won't have this ROM IOS version, so that means I can't use USB to boot then? Will that means I am down to tftp server option? ( I heard xmodem won't work as it will time out before the ios can load via the slow dialup link into the router to rescue it from rommon mode).

I remember there is one command which can tell you which memory slot has how much big memory in Cisco 2800 or 3800. But at this moment, I just couldn't recall this command. I checked "show diag" but didn't see any information about memory.

I am trying to configure two 3845 routers to act as dhcp server and dhcp relay. Clients are connected to the router that relays all dhcp requests to the vrf instance which is used to connect it to the router wich is running dhcp server.
Router1
ip vrf dhcp_dns
rd 8:1
int gi0/0
ip vrf forwarding dhcp_dns
ip address 192.168.200.5 255.255.255.248
[code]...
So far I can see dhcp requests coming from the R1 and dhcp server on R2 replies with the dhcp offer but PC is not getting any ip.

Our ISP hands us an ethernet link. ISP router has one address of (for argument sake) 1.1.1.0/30 net, - let's say they have 1.1.1.1 we have the other usable address of 1.1.1.2/30 assigned to our 3825 router. Is it possible to use hsrp or vrrp if there is not two valid/unique "wan" IPs to assign to our routers? For example, if we had a pair of 3825 routers? are we stuck with basically a manual failover or requesting our isp to provide a larger address wan block?

We have some ASR WAN routers which have a dedicated 400M interface to a remote site.
Servers on our Local network source the data through some firewalls via 10G interfaces, which connects to 4500X WAN switches then to the Routers on 1G links.
The sources are rate limiting the traffic but the routers are periodically dropping packets which I think is mostly due to burstiness in the traffic between as it traverses through from 10G links to 1G then to 400M.
How to setup traffic shaping on the 4500X outbound port to our WAN routers.I'd like to see if we could buffer and smoothe out the traffic as it exits the 4500X WAN switch 1G port to the WAN Routers.

I am buying a Nexus 5K (N5K-C5548UP-FA) with the layer 3 card (N55-D160L3 - Nexus 5548 Layer 3 - Daughter Card).The switching capacity of it is 960 Gbps but I know I should expect less doing the Layer 3 function (it will only be used with static routing).What switching/routing capacity should I expect? How can I estimate it? What else should I consider?

we've had an issue with our network, we have 2 6509 connected with redundancy, which are connected with 2 x 4900 Switches, from which are connected to a ESX Chassis for visualization, the thing is that the ESX stopped working, and the 4900 switches, and the main core were suffering from overload, they hang on it very well, in order to stop the overload, one of the links to the ESX Chassis were disconnected from one of the 4900 switches. The CPU usage from the 4900 and the core(6509) went down below 40%, and then they started to migrate the virtual servers from the chassis to another 2 chassis that were added right after. They were actually working well, but suddenly the 6509 changed to the other supervisor after everything was OK. We were wondering what could have been the cause of this, maybe the virtual servers migrations, maybe the overload from the ESX ? We also had a few question, is there any need to reload the cores every few months as a planned task ? Because the cores have been up for more than 1 year. And also is there any kind of of tool to monitor the CPU status, or the status overall from the cores or the switches ?

I am facing an isssues with 7609 for LAN switching , based on LAN (VRRP/HSRP) feature.Actually we are having ES+ cards (on 7609) and we are using multiple groups(say 350 vrrp groups) running on the router . the routers are connected as router 1>>> mux(which is working as switches)>>> router2
my questing are
1. does their will be "multicast packets" (for VRRP/HSRP group) "from backup router to Master router", when in stable state( ie when Master and backup are already chosen) , or the packet from backup to master should be unicast.I know for sure, the packet from master to back is multicast packets denstination to Multicast IP packet and To MAC address.I am not sure but I think from backup to master it should be multicast
2. what is frequency of these packets( from backup to master)
3. As i have multiper group on a single interface ( we are using q-in-q), when the connectivity from router's is broken, then does all the groups will muticast their active roll in the lan sengment "at once" or it will be in a groups say 100 groups at once, and after few ms few 100's and sone ( as is on OSPF or RIP)
we are in between troubleshooting I hope we get the ans( Actul problem we are seeing in the router's that we have 2 ports on active routers and 2 ports on standby router , but we are not seeing muticast on 1 port on standby router where as all other 3 ports are seeing multicast packets) [code]
