Cisco WAN :: ASR1001 BDI Configuration Equivalent To BVIs And Bridge-groups?
Jul 26, 2012
I have been asked what the equivalent of bridge-groups and BVIs is for an ASR1001 and I am struggling to find an example.If we have this IOS configuration:
I have a site that is very dense, but not high throughput. I have 4x48 port switches all 3560 and 1 2851 router. The switches are pretty much full to the brim but the site is never completly lit, they just like to move around a lot. However i wanted to provide this site with as much redundnace as possible. So my first thought was to build redundant pathing with the switches so that they could loose a switch and not have a single point of failure. So therefore I built a ring. SW1 to SW2, SW2 to SW3, SW3 to SW4, SW4 to SW1. To make this even more redundant against port hardware failure, i used two uplinks for each and built an etherchannel. is it good practice to use Etherchannel and Spanning Tree together?So i now have a good redundant LAN switching topology. I have multiple VLANs at the site so I am using Rapid-PVST. I did not set priorities on the switches as I don't think that is really truly necessary, but correct me if I am wrong!Ok so next step is to make sure that my WAN connection for all of these switches is redundant. I have a 2851 router, with 1 of the built in interfaces dedicated to our ethernet hand-off WAN connection (MPLS in this case using BGP routing). The other would be used as an uplink. I also got an additional card for the Router so that i can have redudant local LAN connections. I then built up some IRB bridges so that I could uplink the Router to SW1 and SW3. Is it good practice to use IRB Bridging on a Router to provide redundancy?So at this site i have the first part running, and it works pretty well but I have had 1 strage issue, which has to do with after a failure and re-convergence of spanning-tree, it seems that DHCP starts failing to work. I actually had to go into each of my switches make a dummy VLAN interface and put on helper-addresses to get them to work. They are not L3 switches (programatically speaking) so they should just forward the broadcast packet onto the router, which DOES have the helper-addresses programmed,Also at another site I have the bridge router setup configured, just without so many switches, and no etherchannel between the switches. This seems to work flawlessly, but the site is very small so performance issues would be difficult to spot since they are just thin-clients coming back to a Citrix server over a single T1.
I have 2 5508 controllers in a mobility group. Any good way to keep the configuration between the 2 controllers synched up?
I thought about copying the config from my primary controller to the secondary controller, but I would think there is a more elegant way to make this happen.
I created some User Defined Groups in LMS 4.1, now I want to apply certain fault notification groups to Event Sets.
Unfortunately the Groups I configured are not in the Group Selector of the Fault Notification Group: Admin > Network > Notification and Action Settings > Fault Notification Group
Someone already do a bridge configuration with 1524 AP? I read Cisco documentation, and is not very clear regarding configuration on switch side.I will do a Bridge in trunking mode, so i want to know what is the VLAN i need to set as native vlan on the switch trunk port.Do i need to set the management vlan as native VLAN?
Is it possible to assign a single ssid to multiple interface groups by assigning the ssid to multiple AP groups?
I have buildings geographically dispersed that are configured with multiple vlans in interface groups so that I can maintain an addressing scheme of dhcp assigned addresses per building. Each building is also further grouped as AP groups. I'd like to know if by assigning the same wlan ssid to each of the AP groups, will I maintain addressing integrity for each building? I'm thinking it will work.
Do the buildings have to be outside AP range of each other to avoid problems?
I have two 1262N access points with 5Ghz antennas, and I have configured one of them as a root bridge and the other as a non-root bridge; both using the same ssid. I have enble both dott11Radio interfaces on each access point. The problem I am having is that they do not associate. I have not configured them for any encryption or security. I just want to make sure the connect before I add any other configuration. Is there anything else that I need to configure to make them associate.
I am wondering what is the TOS value equivalent to DSCP value AF31? I am wondering what is the TOS value equivalent to DSCP value AF31?I have tried to use the charts but I couldn’t understand how to convert it.
i need to know if the built-in GE ports in ASR1001 or ASR 1002 (-X) have the features of QoS without restrictions, or QoS features are supported in SPA modlue ports only?
I found this sentence in 1552 AP guide."AP1552 comes only in the Bridge mode and the mode cannot be changed. A mesh access point performs CleanAir function and also serves clients on the assigned channel similar to the way the Cisco Indoor CleanAir AP3500 (nonmesh mode) operating in LMAP mode serving clients on its assigned channel. The mesh AP also monitors the spectrum only on that channel."We want to use this AP as a local AP ( not for mesh deployments) and serve our wireless clients. The main thing why we need this is just operating temperature. Is it good choice? Does it will function as "normal" local AP or we will have any problems , because of that "mesh" mode?
i'm trying to accomplish the following:I want to trasport a bunch of vlan layer 2 etherchannel on a pair of layer3 connections, using L3 to load balance.i was considering a pair of options:
1) bridging + gre (non applicable since i cant bridge 2 interface beloging to a etherchannel to a tunnel)
2) L2TP is it possible to accomplish this with the above tecnology? any reference, configuration example?
3) AoMLPS is it possible to accomplish this with the above tecnology ? any reference, configuration example?
I cant modify topology, the routers used are ASR1001 It is mandatory that both sites have a layer2 connection between them.
I noticed in RME inventory, my ASR1001 hardware is not recognized. I checked my Ciscoworks and it only knows ASR1002, 1004, and 1006 routers.
I checked the supported device table for LMS 3.2 and did not find ASR1001. Is there a separate device package I can download. This is not a deal breaker, but it's unnerving to see the question mark icon next to the name of my router in the Cisco works GUI.
Is there any way to see on what ports a Cisco 5510router is listening to just like a "netstat -an" on UNIX would do. I could easily do a portscan to give me this report but would prefer having the information through a show command.
We are looking at buying an ASR1001 but I'm confused by the Licenses and I've struggled to find the information in the cisco data sheets. The router will need to run IPSEC on gre tunnels and I figure that I need the IPSEC license (FLSASR1-IPSEC) do I also require the Advanced IP Services license? or is all that is required the IPSEC license? Is there some sort of list that shows the feature set of each license, they cost the same amount so I'm not sure which license fits what we require best or if we need both.
I want to load balance my Internet traffic between two ASR 1001 routers that are connected to our core switches. Both routers are connected to the same ISP (Comcast) going to the same BGP AS on different /30 subnets. Is there a way for me to load balance my Internet traffic using both connections with BGP rather than having one of these connections sitting idle? If not, the only solution I see is to configure my layer 3 devices to split internet traffic between both routers (i.e. default routes with same AD).
I was doing some research on the Cisco ASR1001 model Router and within the description on the official Cisco page it mentions having various models that come with an "Integrated Daughter Card" or "IDC". I was curious as to what the IDC is exactly, considering there is an ASR1001 model without it.
I've done a similar solution before where I put bandwidth inherit on the Dialer interface of the CPE and it inherited the ATM interface speed (the upload sync rate) and prevented the CPE from maxing out and hitting hardware queuing in the DSLAM. I can't seem to find a way to do this downstream from our ASR1K to the customer though.
Platform is ASR1001 with IOS 3.7.2 or 15.2(4)S
Problem description:We have many xDSL users (ADSL2+ and VDSL2). They all sync at different speeds depending on how far they are from the DSLAM.
Example:
Customer A might be connected at 40000kbps/10000kbps (VDSL2) Customer B might be connected at 5000kbps/600kbps (ADSL)
When they connect and the PPPoE session comes up, the bandwidth on the Virtual Access Interface is equal to the customer's downstream sync rate, so Customer A's virtual access interface, Virtual-Access 2.13 will say 40000kbps, and Customer B's virtual access interface Virtual-Access 2.39 will say 5000kbps.Using RADIUS, we apply a sub-qos-policy-out to the PPPoE session.I want to shape the customer to 80% of their sync rate so that we do not hit interface congestion in the DSL network which makes VoIP perform poorly.I cannot use an absolute value for the shape, because the sync rate varies for each customer.The problem I have is at present the policy-map is using the interface bandwidth of Gi0/0/1 (1Gbit) instead of the bandwidth of the Virtual Access Interface. Therefore the customer is being limited to 800Mbit which means the QoS policy will never take effect.
RADIUS Config Below:
cisco-avpair += ip:sub-qos-policy-out=QOS-POLICY-OUT-PARENT-DSL Class Maps class-map match-any QOS-CLASS-VOIP-RTP-DSL match protocol rtp audio match access-group name QOS-VOIP-RTP class-map match-any QOS-CLASS-VIDEO-RTP-DSL
I want to take 100Mb incoming from a service provider and police it off into several VRFs for customers.One of these VRFs will be 30M.I further need to traffic shape this (30Mb) out to 40 x 0.75Mbps (burstable to 30M) customers.
Does VPLS is supported on the Cisco ASR1001?With the feature navigator it looks like the ASR1001 is the only ASR1000 series router with VPLS support but I can't find any documentation confirming this.
I've configured an static route in the ASR1001 router with a name with it eg: ip route 172.20.x.x 255.255.0.0 172.20.x.x 255.255.0.0 name To_system_X.i want to change the name without removing the route.
