Cisco Switching/Routing :: L2 Bridge On 1921 Interface?
Nov 20, 2012
I need to set up a L2 llink between my LAN and this 1921 router. I though IRB would do it but its not working yet. Here is the topology- I dont want to see another hop on this 1921 rtr so I hope I can just trunk it or something with IRB. Not working.
We want to puchase new Cisco ISR 1921/K9 . i want to know does it support the following sample IP-SLA commands
ip sla 2icmp-echo 172.16.1.2timeout 500frequency 1ip sla schedule 2 life forever start-time now
track 10 rtr 1 reachability delay down 1 up 1 ! track 20 rtr 2 reachability delay down 1 up 1 ip route 0.0.0.0 0.0.0.0 192.168.1.2 track 10ip route 0.0.0.0 0.0.0.0 172.16.1.2 track 20
Im asking above question because we will need to enable ip-sla on the mentioned router. as i read on the cisco webside, it says Cisco-ISR-1921/K9-IP Base support only IP-SLA RESPONDER feature nothing else. If Cisco-921/K9 does not support the above commands , should i go for ordering Cisco-1921-SEC/K9 ?
I have the following config using a Cisco 1921. I am trying to get devices on the the native VLAN to get internet access via the gateway x.x.x.73.Any thing being routed from the other Vlans 15/20/30 can get access, but nothing from an internal IP address. Is there something I am missing.
The Xs replace the same 3 octets for each interface.I am trying to route from VLANs 15/20/30 to see VLAN 5. I have tried a few things, in terms of adding extra ip routes, but can't get anything to work. Each of those Vlans have another router on the other side of them, which I have also tried adding ip routes too, but nothing. One of the routers (Vlan15 is a Draytek 2830). [code]
Needing to bridge from my wic interface to an ethernet interface on a 2900 series router so that I can pass through the ip address given to the WIC, to my ASA so that I don't have to give my ASA a private range address. (Just like a service provider might do when bringing a T1 with managed router in to my prem)
I will be installing two Cisco 1921 Routers to connnect a T1 between two offices. We are changing out our current AdTran routers as we would like to bridge three VLAN's across the T1 link. I followed the instructions at (URL) shtml to the best of my ability and my two Gigabit Ethernet ports are tied into a bridged virtual interface (BVI1). I then assigned a IP to BVI1 and another to my Serial0/0/0 then made a route to get to the other side of the T1 and a defualt route out our proxy. What I want to do now is setup QoS to make sure my voice data gets priority.
I setup a QoS ACL called "Voice" with the TCP and UDP source and destination ports that our phone system uses. I then setup a QoS policy on the Serial0/0/0 outgoing interface called "VoiceTraffic" and under the "match" list I match DSCP 46 or my "Voice" access rule. For the action I turned on "Queuing" and set it up for LLQ at 50%. Does this sound about right? Is there anything els eI can setup? I tried ot setup something else on the ethernet side but because they have the BVI I can't. I read some article sin this forum that said I could still apply QoS to the GigabitEthernet ports even if they are in the bridge group but it doens't let me do that.
I am setting up a new 1921 for a public library and I am running into a problem and I bet I am missing something simple. All the internal stuff works and I can ping the outside IP on the 1921 but can't go any further to the internet. The 1921 has the 2 gig ethernet ports, 0/0 is connected to a DSL getting DHCP settings fine from the DSL modem. The other gig ethernet port 0/1 is running the inside network and its function fine, I have a server on it and other clients and they can ping and get dhcp settings etc.I've pasted the config output below and IP addresses of the main actors. [code]
I have already ordered a Cisco ISR 1921/K9. but as i read on Cisco website, it is written that Cisco 1921/K9 only support (IP SLA Responder) feature.
I don't know actually what is sla- responder. but our requirement is we will connect that Router 1921/K9 into 2-ISP links and i want to enable IP- SLA probes on that router so that it can track both the routes into those isp links. so my question is does CISCO 1921/K9 have the support for what i need ?How about Cisco 1921-SEC/K9 ?
I have recently configured a cisco 1921 router for internal routing on my network. Here is what i am trying to accomplish:
Main network 10.65.1.0 mask 255.255.255.0- all office devies and computers. Second network 10.65.2.0 mask 255.255.255.0 - All plant equipment machinery and production lines
i have configure gig 0/0 for my company network and gig 0/1 for my plant network. I can ping the router from both networks but am unable to route traffic betwenn them. what am i missing?
Im having some major issues with my new setup. I have a Cisco Router (1921ISR) that is connected to the internet through a t1. In addition to that is another cable modem. Each of these are connected to my firebox through an external interface.My router is on the 10.1.10.X network. My internal network is 192.168.1.X I have several NAT statements on my router pointing to 10.1.10.X addresses. These addresses are defined on my firebox as seconday external addresses and I am SNAT'ing them to 192.168.1.X addresses on my local LAN.This is mostly working well for everything. However, there is an FTP I am connecting to through the a VPN on the cisco that will not connect. The source is a 192.168.1.X address.
We purchased a cisco 1921 router to replace a software firwall not long ago. The router was sold as a firewall with the suggestion that an ASA would be unnecessary.Unfortunately a router does not replace/do the jobs a firewall does, so I looked online and noticed that Cisco do offer firweall security features in one of their IOS.How do I tell if this is implemented on my router?If not, does my IOS support this, or do I need to buy an extension/another version of the IOS?,The version of the IOS I have is: c1900-universalk9-mz.SPA.151-4.M4.bin.
The Cisco 1921 router has two routed adapters. One is GE0/0 which I am using for my WAN interface. It is working properly. The 2nd interface is GE0/1 which is being used as my internal adapter. It is running NAT. When I attempt to reach the internet it fails while checking the exit interface. Here is the report.

I am trying to decipher the differences between the two models of the 1921 router. One has an IP Base IOS and the other has a Security IOS. I have an ASA so I don't think I need all the Security IOS bells and whistles on an internal router. Although, does the IP Base IOS allow for trunking and sub interfaces? I definitely need that and on CDW's website it says that the 1921-Sec/K9 w/ Security IOS includes 802.1Q and that spec is not listed on the 1921/K9 IP Base IOS model.
We recently got a 1921 for our main office and we have a dedicated 15/15 connection. We're running on an 1871 right now that is not under my control so I can't even see it's running config. OK! So when I set my gateway to be the 1871, we can get our upload to over 6mbit (we have 8 branches, so won't ever get full 15 since they're using it too). With the gateway set as the 1921, it seems like we're stuck at 1.5. I haven't seen it go higher than that. I've looked over the config but can't see anything that would imply some kind of bandwidth limit but I have copied the config here.

I bought a cisco router last week. The reseller said it is a brand new one. However, when I try to set it with console cable connecting to PC, the default password does not work. I tried to use control+break to get access to rommon for password recovery. The tera term pro displayed nothing at all! In thin case, what should I do to setup the router? Dose the reset button in the back work to restore the router to factory setting(which means i can use default username and password)?
I have configured HSRP with InterVlan routing. All communication is flowing properly between the vlan's on Router A but when I test failover to Router B I cant ping ANYWHERE. I cannot ping any of the VLANS.
Also, From the primary router I cannot ping any of the interfaces on the secondary router.
I have 2 Cisco 1921 Routers configured for HSRP. Both the G0/1 ports plug into a Cisco 2960S 48 port POE switch (STACKED) (port 1 and port 2 which are trunked and allowing all vlans to pass through. And both of the G0/0 ports are plugged into a Cisco ASA5510.
I have attached a diagram of the setup and the interface configs of the routers.
I am running a 15.1 or so version of the IOS on a 1921 router. I have plugged in the external PoE injector into the router, and the PoE light on the front of the case is lit green. I have no options in the IOS to enable power on the EHWIC ports. I have most licenses enabled, including data and security.
We have been facing a problem at my company ! We have a Cisco Router 1921 with one HWIC-4ESW in trunking with a RuggedCom switch RSG2100.When I use the GigabitEthernet port to make a trunk, I create 2 sub-interfaces (one for each Vlan) and configure the Port on Switch as Trunk, the inter-VLan routing works with no problem.But now I need to use this configuration using the HWIC-4ESW on Router, and I can't do this work. I try creat interface Vlan for each vlan, and try creating the VLans at Router Vlans database, but no way. At router I enter in interface and try to do the switchport trunk command to add a Vlan, but doesn't work.
How do I chose a router? Network has about 100+ devices across a campus with remote sites connected thru metro-e.Thinking of a 1921 to use as core router.
i cant resolve one problem in may 1921 isr router, i have a web server in my internal lan , i set up static nat for accessing that web server from outside and it woks fine but i cannot view that site from internal workstations can you suggest me what to do. as i know when request gets to router it performs static nat and sends packet to the web server, but the server responds with its private source address instead the public address witch workstation expects and connection cannot established.
I have a Cisco 1921 Router, a Cisco Catalyst 2960 and a Cisco Catalyst 2970 and I want the router to be able to assign ip-addresses by what VLAN a device is active on.
VLAN1: 10.0.0.0/24
VLAN2: 10.0.1.0/24
The router is connected to the Catalyst 2960 and there on to the Catalyst 2970 so the VLAN1 and VLAN2 is active on the to switches and the Router.is it possible?
I have a 1921 K9 with a 4 port 10/100/1000 EHWIC switch.
Interface 0/1 = 192.168.1.0 EHWIC = 192.168.5.0
I have Active Directory setup on the 192.168.1.0 network. When I attempt to join the domain from 192.168.5.0 it joins but I get errors. After some troubleshooting using portqry I have found that the services related to class map DomainTrafficUDP are being reported by portqry as being filtered regardless of policy map settings (currently set to allow).

I have a Cisco ASA 5505 and I have my internal and external interfaces configured but I currently cannot ping from the inside to an IP Address on the outside. I had this setup and working and I have another set of equirement that I am replacing that is working with my service provider so I know it is a configuration issue. When I ping 4.2.2.2 for example I get:
Destination host unreachable
Do I need to add a static route from my inside interface to my outside interfaces?
I have the requirement to provide a Cisco Router with 3 x ADSL lines (768k) to increase the internet speed.PPP multilink is not supported from the ISP.
Is it possbile to distribute the traffic between this three ADSL lines?How can I configure this?
I have the following hardware configuration:
1 x CISCO1921-SEC/K9 2 x EHWIC-VA-DSL-B
The third ADSL line is connected over an ADSL modem at one fixed Router Gigabit interface.
I wanted to know about EHWIC 8-Port configuration? We create Data and Voice VLANs and assign 8 ports to the VLANs. So how do VLANS communicate with each other? We cannot make Gi0/1 as sub interfaces and assign the same subnet IP’s as of VLAN IP’s , it wont accept. On 1921 router Assume Gi0/0 we connect to MPLS WAN. What happens to Gi0/1 where do we connect this?
I'm trying to identify a Cisco router that will give 300+Mbps through a 1Gb WAN port. I think the 1921 can get up to around 300Mbps with the on board RJ45 ports, but are there any other/better suitable models?
There's no need for any other particular functionality or feature set, the routers aren't doing anything fancy or unusual - it's the achieved throughput that's important.
