Cisco WAN :: Setup EBGP Session To 2801 CE Router
Mar 29, 2011
I have setup an eBGP session to a Cisco 2801 CE router. The BGP session establish, however, the session keeps resetting after 90 sec which is the BGP keepalive holdtime value.
On the PE router I found that the OutQ doesn't clear = 22 when doing a "sh ip bgp x.x.x.x summary" - Session reset at 1:30.When I filter the amount of routes advertized to the CE neighbor with the "neighbor x.x.x.x prefix-list out" - I see the OutQ clear = 0 and the BGP session remains up.
-Number of NRLI advertized without prefix filter = 172
-Number of NLRI after filter = 52
why the OutQ doesn't clear.

I want to set up my LAN to have internet access via my 2801 router.The 2801 router is connected to my home ADSL router.Now do I just configure a 0.0.0.0 'gateway of last resort' on the 2801 router pointing to the interface leading to the ADSL router ?Therefore, all traffic from my PCs that is internet bound will head out to the ADSL router and onto the internet.

I was trying to setup an Remote Access VPN using ISR 2801. I was able to establish the vpn tunnel from my house using DSL Connection (behind NAT), the ISR give the IP address which is from the ip pool that I configured on the ISR. The problem that I have right now is that it fails reaching the corporate LAN network.

I have a setup where a router learns a subnet from both EIGRP process and a BGP process (EBGP peer). In the network's normal state, the EBGP path is preffered path (Primary Path). When the route to the subnet is lost in EBGP, then the router will install the EIGRP learn route into the routing table and use that as its path to get to subnet now (Backup path). This works as expected.
The problem is when the EBGP learn route comes back, the Router still holds on the EIGRP learned route in its routing table. I would think that since the Admin Distance (AD) of EIGRP (90) is higher then the EBGP AD (20) that once the EBGP route is learned again, that it would re-install itself back into the routing table (replacing the EIGRP learned route). But this is not happening.
Im not sure what Im missing here since I thought AD was highest considered attribute the routing table consider when install a route learned from 2 routing process.
The setup Im running is an Cisco 7206VXR (NPE-G2) processor (revision A) running IOS c7200p-spservicesk9-mz.124-15.T12.bin.

a customer of us asked if C2911 (to be bought) is ok for partial BGP routes.This is the situation: 2 cisco 2911, each peering with 3 other AS (AS1, AS2, AS3), and maybe, in the future, at a small IXP (AS4, AS5, AS6, AS7).They will accept defaults plus partial routes from upstream AS1, AS2, AS3.When deployed at the IXP they also will accept partial routes from AS4-7.So, is 2911 ok for that configuration?the default route is included in the first row of as-path, isn't it?I have no experience with partial routes, only with full (for our datacenter) and default only (for other customers).

I would like to know how long a route would maintain its community tag when it traverses ***?Basically, a route is tagged 100:1000 when exiting AS100, and then accepted into AS200. AS200 will not modify the tag. Would AS200 export the route to AS300 with the same 100:1000 tag?

My 2811 is connected with two ISP,s as below and have VPN with Central branch.I want to set DSL as primary and WiMax as secondary but problem is that routes learned via BGP get precedence over default route as they are specific one.I think i may need to put all static specific routes of central branch over DSL along defautl but I want any idea if my default route stay active and when it down then BGP neighborship can be establish (like ip sla tracking.)

I have a mixed WAN environment with both eBGP and EIGRP routes. The BGP routes should always take precedence, when they exist. If no BGP routes exist I want the router to fail over to using the EIGRP routes. So far, this works fine.
The problem is, when the BGP route again becomes available (and the associated entry appears in the "sh ip bgp ... received-routes" output) the router is NOT relinquishing the EIGRP route. It remains in effect, showing as a "D" route int the route table even though there is a better ("B") route available. If I bounce EIGRP or the interface associated with it, the EIGRP route disappears and the BGP route reasserts itself, and everything will run correctly until the next time the BGP route disappears due to maintenance, line failure, etc.
My router is (C2900-UNIVERSALK9-M), Version 15.3(1)T
Here's the associated config
interface Tunnel101
description VPN backup WAN interface
bandwidth 7168
ip address 192.168.75.1 255.255.255.0

I am imagining a smallish networking (AS1234) with say three full BGP table peers that provide transit to the network (just to keep the maths simple here); Lets say AS100 and AS200 are preferred transit providers with AS300 as a backup/least prefered (AS prepends or similar stop us from using this network by default). So in this scenario our little network gets two different paths across the Internet, as not to rely solely on one provided, with a backup provider to hand also.
How do you mange issues like packet loss somewhere in AS100's or AS200's network? So lets say a host on our AS1234 network is talking to host in AS888 and the preferred route is through AS100 but somewhere deep in AS100 a link is flapping (for example) and I can't get to AS888 reliably through there anymore, but I can through to other peers of AS100 OK. We can postulate that AS100 is the best path for 50% of the Internet and AS200 for the other 50% (this is a best case fictional scenario). I can't ping 50% of the internet via AS100 and then in the event a ping fails (or some other more reliable test) tear down the BGP session to use AS100 until it's fixed again, nor vice versa with AS200.
First of all, I asume you don't know about the issue between AS100 and AS888 until someome moans about it to you? Secondly, do you then some how modify the route(s) to AS888 that come from AS100 (route map for example to change the weight or preference) so AS200 is now preferred for AS888? Do you infact shut down the AS100 peering and now use AS200 & AS300? How do you rectify these situations that are beyond you control using what is in your control?

My client has MPLS network via eBGP to communicate with all the sites. Here is the basic config on the router.router eigrp 65210.neighbor 192.168.1.2 remote-as 13939
When they installed the internet on the local router, and added the static route on the router to hit the internet, they need to add the static route (2nd one) to communicate to the other sites.
ip route 0.0.0.0 0.0.0.0 75.75.75.1
ip route 192.168.0.0 255.255.0.0 192.168.1.2
ip route 172.20.0.0 255.255.0.0 192.168.1.2
They want to route all the traffic out thru the local intenet besides their private networks ( 192.168.0.0/16 and 172.20.0.0/16). Are there ways not to add last two static routes and communicate the other sites via eBGP?

I looked but could not find any information on what's the use of the USB interface on my 2801 router. I saw something about Cisco USB memory module and eToken by Aladdin. Is this interface restricted to Cisco and Aladdin only?

I have a Cisco RV110W small business router setup at my home. It has one of those HTML GUI interfaces, check the boxes, etc.., to get things working. Basically, your typical home router with VPN. I have enabled the VPN, it's PPTP, added the password, and now it's automagically configured! I can successfully VPN to my home with a Windows7 client. Here's my problem, I now need to VPN into my home router with a 2801. Is this possible? Everything I found on the subject has only been to setup a Cisco IOS router as a VPN server or tunneling to another IOS router. No examples using an IOS based router as the client.

I'm having trouble setting up a Cisco 2801 as an internet router between our firewall & our ISP.I've setup FastEthernet0/0 as the WAN port & FastEthernet0/1 as the LAN port. I've setup a default gateway pointing the next hop (the ISP),when I plug in a pair of laptops configured to mimic our IP scheme, I'm able to ping thru, but when I put the router between our firewall & ISP I'm not able to get out to the internet (can't ping google) I can still ping the next hop.,Our old router died, so I am unable to pull up its configuration. Here is the code I'm come up with so far.

I need some clarification if it is possible to do an IPL connection between Cisco 2801 (T1) to Cisco 1841 (E1) via Ethernet (2801) to Serial (1841).
I am unable to find any documentation about this and I need to connect our network to an offshore network.

I have to configure failover on both router. if one get fail then the other router should be dial.Physical connection
•1. Two routers (Cisco 2801) are connecting with splitter through RJ 11 port.
•2.Only one ISP link is coming in splitter.
Requirement: As per as customer requirement. He wants redundancy with in both 2 routers. If one goes down then the other router come up. And same configuration on 2801_R2 router. I am planing to do HSRP on our lan network (2801R1,2801R2 ehternet interface which connected to switch). from switch i will create two default route with (next hope) virtual ip address.

I have a 2801 router with a HWIC-3G-cdma card that I have inherited from a predicessor. How to use a cellular card on a router and need to get this thing up and running. Any example config that I can see or point me in the right dorection to get this up and running? I have the cellular card set up as Cellular0/1/0 on the interface, I assume that that was done by default, and it has an IP address. The Static Route of 0.0.0.0 0.0.0.0 Cellular0/1/0, in the config with only 2 other interfaces as being direct connection. But that is as far as I recognize. Do I need to set up a router protocol? Which one? How do I use the cellular card? Do I need to have an ISP connection?

I have just received Time Warner Cable and get 16Mbps down from them directly through their modem (motorola DOCSIS 2.0 modem- SB5101) to my PC (using speedtest.net). When I then connect TWC's modem through my 2801 router on fa0/0, the download rate I get is considerably slower (on the order of 3-4Mbps via same testing method). What am I missing?
Here is how the passthrough interface is setup:
interface FastEthernet0/0
bandwidth receive inherit
ip address dhcp
ip nat outside
ip virtual-reassembly in
duplex auto
speed auto
I have attempted removing bandwidth command - nothing changed with it not there. I have also hard coded the speed and duplex to 100/full to no avail....
Other possible relevant configs:
ip nat inside source list 1 interface FastEthernet0/0 overload
ip route 0.0.0.0 0.0.0.0 dhcp
access-list 1 permit 192.168.1.0 0.0.0.255
Basically this things is wide open... for testing but the download speed differential is perplexing to me.

I need some clarification if it is possible to do an IPL connection between Cisco 2801 (T1) to Cisco 1841 (E1) via Ethernet (2801) to Serial (1841).
I am unable to find any documentation about this and I need to connect our network to our overseas office.
Our side uses the 1841 router and our provider has set-up our E1 connection to be via Serial interface while on our overseas office uses the 2801 and will connect via the T1 card, which by the way does not have any serial interface ports just ethernets.
So far checking on how to configure this, I am unsure on how the connection will happen since the info that I got is that T1 does not have the option to hold an IP address (also unsure on this though). With this in mind and that the 2801 does not have serial interfaces, does that mean that IPL connection would be via the available Ethernet ports?

I have 5 routers. Four routers are: c2801-IPBASEK9-m v 12.4(24)T2. One router is a C2800-IPBASEK9-M v 12.4(24)T3. so, it appears that the IOS on all 5 routers is very similar, the only difference is the T3 at the end of the version and that 4 are 2801s and one is a 2800. What is very wierd is the 4 2801 have the embedded scripting language "tclsh". The 2800 does not have tclsh. If I issue the command: tclsh on the 2800, I get:
Center-GW#tclshTranslating "tclsh"
% Bad IP address or host name% Unknown command or computer name, or unable to find computer addressCenter-GW#

I have problems with the Router 2801.When i give the command show processes cpu, the command show me that the router is working in 98%.
I have vlans like voice vlan and others, I have one 20 Mb Wan Link and I redirect all traffic from my lan to this link and when i browse in internet or i do downloads the router goes to 98%, when i don't make it the router processes goes down.
I thought be problem with hardware, but i exchange to another router and the same problem happened.Before this situation, I had one link with 12 Mb and nothing happened, when i exchange this to the 20 mb link the problems starting.

I have one problem doing a ping to a router lan interface, I have 3 routers (2801) connected between each other (separated 1 mile each), the link is established trough microwave signals (connected to the 2801 fast ethernet interfaces), every router has a connection to a LAN. One of them is located at headquarters.Last thursday I replace one of the router with a cisco 2901, i configure the router with the same configuration that was on the 2801, i power up the router and the 2 link were up without problems.One day after the noc called me to tell me that after i replace the router they can't ping the router IP lan interface on the new 2901 (before the replacement the ping was sucessful). I called one user the lan connected to that 2901, and they can do a ping to the router's LAN IP address.
I can ping the 2901 IP wan interfaces, I can ping the LAN users ip address, but i cannot ping the router LAN IP address, from my desktop, and neither the 2 routers 2801 connected to the 2901.I show the configuration on the 2901, I couldn't change it because i didn't have time to do that, but i'll change the configuration to use ipsec tunnels.The configuration as you can see, has a crypto map, but the acl used by the crypto map, only permits the interfaces ip address, so i think that doesn't work, so the traffic doesn't get encrypted, but i don't know if that is the problem why i can't do a ping to the lan interface.

I'm using for a company network a 2801 Cisco Router. This router has 2 FastEthernet Interfaces connected on 2 ISP's and one VLAN for internal users. What acl should i use if for example one client from the lan is using a torrent client to download from the internet. I want just to specify a maximum download speed or to block that client to access the internet when it's trying to download something that can affect other clients from the LAN.

The goal is to add a 2801 router between a DSL modem and a switch and obviously still access the internet. I connected and configured as explained below and the results are:
- I am able to ping internet addresses from the 2801 router
- I am not able to ping internet addresses from userlaptop but I am able to ping LAN gateway (192.168.254.254)
I cannot understand why the internet requests from the user laptopuser are not routed to the internet but the router itself can access the internet.

simple configuration of a 2801 Router. I have 2 internet providers with static ip's connected to F0/0 and F0/1 and one Vlan for LAN area. I would like to configure the router to use one primary line and just in case to use the back-up line. [code]
Now if detects that it hasn't cable link on the FastEthernet interfaces it's working. I'm using 2 wireless gateways to acces the internet each one connected on the 2 FaEth for simulating the providers. If i simulate an issue on the provider ( i've removed the sim from the wireless gateway) it doesn't pass on the second isp.I haved trying to configure with "IP Service Level Agreements " for failover / load balancing but the command "ip sla" is incomplete. I can't make an update of the IOS because the customer do not have an Service Contract with Cisco.

It also dosnt show on show cdp neighbors?

We have recently implemented some QoS on our routers and i have noticed that the CPU usage has risen enormously as a result.
I checked the CPU Processes and found that the avg values are 50% usage. This seems rather high considering that only 75% of our edge routers have this feature enabled.
Our main router is a Cisco CISCO2911/K9 (revision 1.0) with 487424K/36864K bytes of memory. Our edge routers are either 2801 models or 881 models.
This is our first implementation of QoS and would like to ensure that it is working properly before implementing other QoS rules. Here is a copy of the config on the 2911 router:
class-map match-all Citrix
match protocol citrix
class-map match-all Print
match protocol printer
class-map match-all C-Coolingata
[ code]......
Here is the config on our edge routers:
class-map match-any Citrix
match access-group name Citrix-ACL
[code]....
As you can see we have different link speeds at different sites based on their size, location etc. How to be able to confirm that this config is correct?
