Does a Router support 2 BGP As in one router

Does a Router support 2 BGP As in one router. I have gone through the below Cisco page, however my router is not allowing to enter the second AS in the router, it is giving the error as usual " BGP is already running; AS is XX" .
http://www.cisco.com/c/en/us/td/docs/ios/12_2s/feature/guide/fsbgpdas.html#wp1056689
My Router :- Cisco 3845
IOS Version :- c3845-advipservicesk9-mz.124-24.T8.bin

Hi,
You can not run multiple BGP processes on a single router with each of them being in a separate AS. What you can do, and the link in your post explains that, is that towards a particular eBGP neighbor, you can use the neighbor local-as command to appear to be in a different AS than the one you really are in. So you do not start two BGP processes, you just make your single BGP process to appear to use a different ASN on a particular eBGP peering.
Best regards,
Peter

Difference between sh ip bgp & sh ip route? BGP tables and main routing table.

Difference between sh ip bgp & sh ip route?
sh ip bgp :::: loc-rib ?
sh ip bgp nei x.x.x.x advertised-routes : adj-rib-in.
sh ip bgp nei x.x.x.x recieved-routes : adj-rib-out.
sh ip bgp nei x.x.x.x routes : loc-rib ?
sh ip route = rib ? if yes does it mean its loc-rib ?
so in a given router with bgp running, will there be 5 tables (sh ip bgp; adj-rib-in; loc-rib;adj-rib-out; sh ip route) ? if yes where are they saved ?

sh ip bgp
shows the BGP table (where are stored info coming from BGP update)
sh ip bgp nei x.x.x.x advertised-routes
shows networks that your router will advertise to a specific neighbor
sh ip bgp nei x.x.x.x recieved-routes
shows advertisement received from a specific neighbor; networks (NLRI) filtered with route-map distribute-list,... are included (Inbound soft reconfiguration must be enabled)
sh ip bgp nei x.x.x.x routes
shows only routes sent by a specific neighbor and not filtered or discarded (i.s accepted)
sh ip route
show routing table; it contains the best route for each network (best is first of all the lowest administrative distance, then the lowest metric)

Does CRM email router support digitally signed emails?
i am not able to trace mails in to CRM,, have you ever faced this ???? kindly suggest i need this to figure this out.
Thanks,

Thanks Vinay, glad you got it working. We were having some issues and its related to the level of rollup and whether certain headers are allowed through exchange or not.
However MS's answer is that it does not work.
Confusing eh.

Does Stratus/RTMFP support P2P behind the same NAT/Router?

Does Stratus/RTMFP support peers behind the same NAT/Router?
(such that both peers have the same public IP address)
That is: if two computers (each running Flash) are behind the same NAT, and connect to Stratus to get peerID;
do we expect they can connect p2p?
Or will each one get/see just the public IP address:port of the other?
My initial tests indicate that this scenario fails [ICMP Destination Unreachable (port unreachable)]
Is this just a limitation of my local router? does this work for others?
Does Status expect the local router to detect/decode/resolve this situation?
If the solution requires 10.1 groups, is there support to detect/diagnose when/if the peer is on the same LAN?

Thanks for the info, sounds like RTMFP supports this, and hopefully the AFP code does the right thing.
[so, officially, the original question is answered]
Note: In one instance, i'm running two browsers on the same host,
so even the inner/LAN addresses would be the same. Therefore, if A sends to B's inner/LAN address,
the [Windows] OS network layer *should* recognize that and 'hairpin' without leaving the host, or crossing the firewall.
(I say "should" because Unix generally does that, but I'll have to check to see about Windoze).
[And such packets are probably invisible to Wireshark also, so how do i verify what's happening?
oh sure, just reconfigure to boot Linux... ]
So glad you explained that the client tries all three pathways; if it works as you say,
then I can probably ignore the ICMP error from the local router (or, as you say, teach it to do the hairpin).
Can you confirm that P2P will work between browsers (say Chrome to Firefox) on a single Windows host?
[I really want to know if I'm failing because of network configuration or application code/error;
at this point, I am able to correctly exchange the peerIds, and start the NetSteam.play,
but the two sides do not appear to be exchanging audio/video]

Does sge 2010 support Routing Information Protocol (RIP) ?

Hi, I would like to know if the sge2010 switch support Routing Information Protocol (RIP) and if so how do I enable it. I have a small wireless router that support it and would like client connected on it te bo visible from the wan side and that worked when I had another device doing the routing with RIP support the wireless router was picking up that information and the routing for the wireless client was working.
Thanks !

thanks, thats a shame that a 80$ wireless router support that function and a 1000$+ switch doesn't

Does Airport Extreme support Static Routes?

I have client using an Airport Extreme as their Router. They currently connect to another device outside their network using AppleTalk.
It is planned to put this device onto TCP/IP but on a different subnet (e.g. their subnet is 192.168.5.X and the device will be on say 192.168.25.X). Does Airport Extreme support (like other Routers) the ability to set up a static link to a device on a different subnet (can’t find any information in a doco or the utility) or do they need to replace this with a “real“ router?

Sure, I could do something like route add -net 10.100.10 192.168.0.100 on every client machine on the subnet, but there is no such way to configure a web cam and similiar devices
Any idea, Apple?

Does MMX400R wifi pocket router support for iPad?

I'm using iPad wifi module. I'm planning to purchase MicroMax pocket router 400R. I just want to know the pocket router will support iPad.

no i don't think it does wps. but i think you can still configure the wireless router with the ipad. if you connect to it, just type in the gateway address into safari, logon, and configure
uncle_tungsten wrote:
Sorry, I left out an assumption. The router has not been configured; there is no configured SSIS, username, or password. The wireless router requires an Ethernet connection be made with a PC, to connect to the IP address of the router and configure it.
In my case, I want to configure without using a PC. The router supports the WPS protocol which does not require configuring the SSIS,username, password. My question was whether the iPad supports that protocol. Then, I should be able to enable WPS and click the WPS start button on the router. The iPad should then connect.

I want to use my jetpack 890L as a wireless router to allow wireless printing with a canon laser printer. Is this possible, and does the jetpack support WPS?

I want to use my jetpack 890L as a wireless router to enable wireless printing with a canon laser printer. Is this possible, and does the jetpack support WPS?

I’ve used several wireless printers with a 4510 and 5510 Jetpack and they all print just fine. The MHS890L does not support WPS. The WPS Wikipedia article briefly addresses the reason why you should not use WPS. If you’re having trouble setting up your printer the manufacturer has a toll free support line to help you. Your Jetpack has the Wi-Fi Password on the bottom, under the battery, and or in the LED display.

Does an IMAC desktop come with wi fi router built in or do I need to purchase and connect one?

Does an IMAC desktop come with wi fi router built in or should this be purchased separately? My brother recently bought a new IPAD mini and we don't know how to connect it to wi fi. He has a fairly new IMAC desktop.

No. It comes with a Wi-Fi card for connecting to a router. First, you need Internet service in your household either from cable or DSL. The provider installs a modem or a modem/router. In the case of the former you need to provide the router. In the case of the latter you do not. But a router is needed to create a wireless network in your home.

Webvpn GW's on one router with domain names

Hi,
I'm trying to configure multiple WebVPN gateways on one router using one front door VRF and multiple back door VRF's. Think of this like a cloud service provider with several customers using different VRFs and one Internet VRF used for the incoming connections for the remote users.
Doing so, several scenarios arise:
Using one gateway and several context with a seperate VRF for each.
Please let me know if I am wrong here:
I can only assign one trustpoint because I only have one gateway. This means that all users connecting can only use one domain name like "*.isp.com". This also implies the use of a wildcard certificate.
Using several gateways and several context with a seperate VRF for each.
I can only assign multiple trustpoints because I only have one gateway. This means that users connecting can use multiple domains name like "webvpn.clientA.com" and "webvpn.clientB.com".
I would prefer the first situation but then I run into a second problem:
There are several commands related to hostname and up till now I have not figured out which one does exactly what:
ROUTER(config)#webvpn gateway WEB_GW
ROUTER(config-webvpn-gateway)#hostname
ROUTER(config)#webvpn context CUST1_CT
ROUTER(config-webvpn-context)#gateway WEB_GW domain
ROUTER(config-webvpn-context)#gateway WEB_GW virtual-host
Is there anyone who can explain to me what exactly does what?
My personal guest is that I only need to configure the virtual-host like this" CUST1_CT -> virtual-host cust1.isp.com and CUST2_CT -> virtual-host cust2.isp.com". But I'm not sure about this and up till now I have not found any documentation that describes this very clearly.

I think for this to work correctly and be able to split traffic between the 2 ISPs, you would need to use BGP, because default is going to use one ISP or the other.
If you can use BGP, this link will help you in load shearing between multiple ISPs when you have one router.

How to route traffic across subnets when one NIC is a hyper-V virtual switch?

Having a bit of a problem with a hyper-V environment which does not seem to route network traffic on two different subnets between each other.
If it were a purely physical server with two NICs and a gateway set traffic would automatically be forwarded between the two different subnets.
However when one of those NICs is a hyper-V virtual switch this simple routing no-longer seems to work and no traffic gets forwarded between subnets?
Situation is:
Hyper-V server with two NICs
NIC 1 = 192.168.0/24 - main Internal company network.
NIC 2 (hyper-V virtual switch.) = 192.168.1/24 - connects to ADSL internet router
Virtualized Domain Controller.
One or two virtualiszed NICs as necessary
How then does traffic get routed between these two subnets? If RRAS has to be configured to do this where is the best place to do it, on the hyper-V host or on the virtualized domain controller?
Thanks,

Hi ,
You can create an internal virtual switch and configure an IP for it (I assume it is 192.168.1.2/24) .
After you enable RRAS in hyper-v host there will be two gateways for different subnets .
" NIC 2 (hyper-V virtual switch.) = 192.168.1/24 - connects to ADSL internet router "
The problem is here ,if these VMs need to access internet .
So , these VMs can not configure their gateway same as the IP of internal virtual switch , you may set VM's gateway as the ADSL internet router's IP meanwhile add a static route entry for every VM .
Please refer to the Syntax :
route add -p 192.168.0.0 mask 255.255.255.0 192.168.1.2
Hope this helps

Multiple devices on one router (E1200)

Hello, I've been having this issue with my E1200 ever since I got it. It just can't handle more than one computer. With just my computer connected playing League of Legends, the connection is fine usually about 30-40 Mbps with 100 ping and no lag and I have the 50 down and 5 up from Time Warner (It's not TWC's fault because when I test it connected to the modem I get maximum speeds). But as soon as another computer goes on the Internet or does some simple browsing or video watching, the speeds decrease drastically for both computers down to less than 10 Mbps and gaming is horrendous getting pings ranging from 400-1000 constant. I've been in contact with Linksys support free many times but I can't anymore because to do not wish to spend money for support that should've solved this problem by now. They've told me to configure settings such as turning off WMM, reducing MTU to the appropriate number and changing security mode to WPA2 personal but none of those things made it able to support more than 1 computer without speed drops. I need help because it drives me nuts lagging constantly and I've restored the router so many times already.

That is pretty much my experience with that router (E1200v2), but only when a device with a poor signal is connected. If you get the offending device closer to the router, you may notice that the lag does not occur. It seems like the router behaves like this (affecting all connected devices) only when it's forcing itself through a weak signal.
Things that help:
- Connect the PC/console you play on via a wired connection. Wired connections are not affected by this issue
- Optimize your wireless settings: Get rid of 2.4 GHz phones, baby monitors, etc. (if you have any), and use inSSIDer to determine and use the best possible channel in your home
Things that don't help;
- Messing with WMM (leave it always enabled, unless some issue forces you to disable it)
- Using WPA2. Use it anyway, though. Never use WEP or leave your network open
- DMZ/Port Forwarding/Triggering
- Setting Up Internet Access Priority. This is not an Internet bandwidth issue, but a physical signal issue, apparently
