Cisco WAN :: C2821 - How To Configure Priorities For Multiple BGP Peers
Jun 20, 2012
At our organisation our routers all have at least 3 BGP peers, each from a different connectivity provider. The different providers that we use all have different internet transit CDRs. Is there a way that I can configure a priority for the 3 BGP peers on our routers so that outbound traffic to the internet is sent to the BGP peer from the provider with the highest CDR?
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?
What is the reason of following NTP error. I am unable to configure further ntp peers on the router. Could not able to understand the reason of 100 peers. I am adding only 2nd peer on the router but getting this error. There is no problem adding peers in other 6500s .
I have an ASA 5525 and need to configure site to site ipsec vpn to 3 peers. I currently have an existing /28 public address from my ISP that is used by other services.Is there a way to use this existing ip range to configure IPSEC tunnels to 3 peers ?
My question is if I can configure 3 ssid, for 3 different VLAN and add the DHCP address from a WAP4410N AP, when you upgrade to the latest version of IOS I can have this functionality?
Based on the business requirement, I have installed one more 9 port FE Switch in addition to existing one, NM is discovered but when we connect PC or IP-Phone it is not working, current IOS is flash:c2800nm-advipservicesk9-mz.124-3h.bin with 64MB Flash
I got Two Distribution Switches of Cisco 3750G. Each Distribution have two 3750G switches stacked. I also have one Cisco 3750V2 Access Switch connected to both Distribution. When I am checking for redundancy, I can only get redundancy test pass for one link not atall for other. If I have a link up with Distribution 1 only then its fine; but disappointment with Distribution 2 link. I can see that the switch priorities of Dist 2 is not correct ie. Master's priority is 10 and Member's is 15.
My question is that due to misconfigured priorities on Distribution 2 stack switches I am failing with redundancy if ONLY Dist 2 is up and Dist 1 is down.
Is it possible to configure multiple ISPs in 3560? and These ISPs traffic should be forward different vlans & different ports. i need configure port wise DHCP also and using different ip addresses please, which device supports this application
How to configure multiple WAP321 Wifi at once? Because I need to configure around 100 APs and i want to know if there is any software from Cisco to do it, like a WLC or something else.
I am having problems accomplishing these tasks with my new SG 200-18.
I have a LinkSys WRT54G2 connected to port 1. I would like ports 2-8 to be in one VLAN with access to the Internet and to be able to share their printers, hard drives, etc. with other computers on ports 2-8. I would like each of ports 9-16 to be on a separate VLAN with access only to the Internet and no other ports on the switch. I would like to be able to manage the switch from any of the ports 2-8.
After I create the VLAN 1009 (see screenshot below), port 9 can browse the Internet and cannot see the other ports on the switch which is correct. However, ports 2-8 can no longer access the switch at 192.168.1.20 in order to manage the switch.
I have a location where I have 2 WAN links, but without a dynamic routing protocol in between. I want to implement a kind of hub to 2 spokes VPN. But the spokes will actualy be on one single ASA firewall, each spoke on a different interface. One hub-spoke will be primary, the other one the secondary. When the WAN link for the primary VPN fails the secondary should be started on the hub to the other spoke.
I need to configure a WAP4410N for use on a small, very simple business network. There should be a corporate WLAN and a guest WLAN. The corporate WLAN should allow anyone connectd to it to access resources on the domain.
In front of the WAP is a cable modem/router and a basic Level 2 (web managed) switch. What do i have to do to segregate the corporate and guest networks.
I thought I would add the corporate WLAN to VLAN1 (assuming the default VLAN in the switch is VLAN1). Then I figured I could create the guest WLAN and assign it to VLAN2 which which will be controlled entirely by the 4410N (DHCP, DNS, etc.) Does this sound like the right way of going about things?
I am setting up a Cisco ASA 5505 first time for My organisation, I usually setup Cisco Router, I have 10 Static IP, & Have 6 Server (S-1, S-2, S-3, S-4, S-5, S-6), Traffic Should be pass through the ASA and is distributed to the destination server that is specified in the packet. LAN servers can be separated into discrete networks for security. For example, a private LAN for internal traffic accessed only via remote dial-in VPN sessions and Want to Configure DMZ for Server (S-4, S-5, S-6) that allows public web traffic.
I have Attached My Network Diagram I have some question,
1:- Can we Configure Multiple Static IP On ASA 5505 ?
2:- If Diagram is wrong what change need to be done ?
Had a question regarding creating dial peers through sip trunks. It will be through verizon fios so it'll be terminated through the fa0/0 port. I know to the provider i'll implement something along the lines of this:dial-peer voice 1 voipsession target ipv4:1.2.4.4sipv2port fa0/0Many of the documentation I came across really only shows pots dial-peers will a voip dial-peer work the same? Something a long of the lines of this:dial-peer voice 2 voipdesination-pattern 91[2-9]..[2-]...... no digit-stripport fa0/0
I have a Cisco ASA 5505 which is setup as an EasyVPN client to e remote VPN concentrator.
The Cisco ASA has the 50 internal user license with 10 VPN peers.
We just upgraded the license from the base 10 internal user to 50 user license but it has not resolved the problem and only 10 internal users still work, the 11th fails.
Does each EasyVPN client on the inside network take up 1 of the 10 VPN peer licences?
This seems to be the issue from what I can see, just need confirmation.
I am trying to get a 2811 to accept two IPSec peers however can only get one working at a time. I have setup fa0/0 and fa0/1 with their own public facing IP addresses with crypto maps associated to each interface however can only establish connectivity to one interface at any one time.
I have one ASA with two tunnels. Each going to a different 3rd party Checkpoint firewall (site A, site B) Each site has two servers (A1, A2, B1, B2)I can only connect to A1 and B1. any connection to A2 and B2 fails. I have defined B2 and A2 in the crypto map to be protected.If I only have B2 or A2 in the crypto map ACL then the tunnel fails. Phase 1 does not come up. Its as if the ASA is ignoring the entries for B2 and A2.ASA running 8.4(2).I have also trashed the VPN and built via the wizard, same result.
I'm running 12.2(33)SXJ1 on a 6500 with several IPv6 BGP peers. Is there any way to monitor the BGP status of IPv6 peers? I've been through the BGP4 mib and cant seem find a way to check the status of IPv6 peers.
I am in the process of installing an Aironet 1140 standalone AP. I have not worked with these AP's before. I will be connecting it to one of the PoE ports on the existing ASA 5505. My goal is to have 2 SSID's, one for internal network and one for guest internet only, no access to internal LAN. I want to have the internal wifi clients and the guest clients on seperate IP networks. The internal clients obtain DHCP from the existing server and use the ASA DHCP server for the guest clients. And of course, I would like the ability to manage the AP from the internal network. I am providing copies of my current configs for both the ASA and Aironet.
I have around 60 , 1142 N APs . As of now i have only management VLAN ( for IP ) & one user vlan 350 configured on the access point . All the users connect to VLAN 350 and they get IP as required.However in our new set up there are couple of requirements have come up were in SSID will be the same however we have created many VLANs for different kind of user group and all these VLANs should be mapped to this single SSID and pick the IPs from their respective VLANs .
We have done configuration on the RADIUS server side were in we have mapped the users in their respective VLANs and they are getting authenticated via AD . Now how do i map my these 4-5 VLANs in a single SSID in Access Point.
I have 2921 router and I have 3 very basic switches that I need to connect to the router. The switches have very basic default configurations and there is no way to edit them, so I only have one VLAN and one default gateway. I can't assign the same IP address to each LAN port. I'm not sure how to make this setup work.
I just bought a Linksys E2500, and I'm trying to configure multiple SSID's on it. The "guest mode" won't work for me because I want one SSID to use WPA and the other to use WEP, but the option to set different encryption based on the GHz frequency of the connection won't work for me because I only want the WEP one to be used by my Nintendo DS (which doesn't support WPA); I don't want to force ALL devices that don't support 5GHz to use the WEP one!
We have an ASA5520 configured with a IPSec VPN, from any ADSL home/office our VPN clients can connect without any problem, but when we use our cellular phones in tetering mode (as an accesspoint) our VPN clients are impossible to connect. Same machines,same software, same operating system, same remote IP (ASA5520 external IP) only change Wifi connection (ADSL to cellular phone). The signal of cellular phones is not the problem we was doing the tests with different phones (IPHONE & ANDROID), different locations (all in spain) and differents providers (vodafone, orange and movistar) of internet by cellular phone.We think that perhaps the problem is the licenses that our ASA5520 has..
Our ASA5520 comes with this licenses: ------------------------------------------------------------------------------------------ Licensed features for this platform: Maximum Physical Interfaces : Unlimited perpetual Maximum VLANs : 150 perpetual Inside Hosts : Unlimited perpetual Failover : Active/Active perpetual
ASA 5505 Firmware 8.3(4), ADSM 6.4(2).I have a public IP address of 168.87.3.4.I need to forward ports (5060, 5080, etc.) to one internal address. (192168.1.1).I need to foward different ports (10020-10080) to a different internal address (192.168.1.2) Everything I read tells me how to do this in a 1 to 1 static NAT.
A Cisco RV220W router/firewall connects the local LAN to the internet. The router is connected to a new Cisco SG300-28P switch configured in Layer 2 mode. There are two new AIR-1142N wireless access points running in autonomous mode connected to 2 ports on the SG300 powered through PoE. The AIR-1142N access points are running the latest firmware version 15.2(2)JB. There are two VLANs defined: VLAN1 is the native on all devices, and VLAN2 is for wireless guest traffic to provide access to the internet only.Internal/staff traffic is on 192.168.100.x, and the wireless SSID is MYNetS.Guest traffic is on 192.168.200.x and the wireless SSID is MyNetG.IP addresses are being assigned by the RV220W.
All works well with one exception. Wireless clients on the internal SSID are able to ping/access the switch, router, and other clients on wired ports on the switch. The router, switch, and wired clients can ping wireless clients. However, wireless clients, on the same SSID and the same 1142N cannot ping/access one another. They are being isolated from each other. We absolutely need to have this capability.The SG300 does not have port security enabled on any port. none of the workstations/laptops have a firewall enabled. These laptops are all Macs btw. I have checked that neither of the 1142N access points have Public Secure Packet Forwarding enabled on either of the VLANs.I am at a loss as to why the wireless clients are being isolated.
we recently aquired a managed services job and have to do a overhaul of the vlan configs and have a whole dozen WC2948G's trunk between a set of ports as well as trunk out a LAG channel setup to non cisco equipment. the deal is the lacp-channel works properly on both ends but no routing of vlans between ports and between the lag trunk are working.
theres alot of settings in the config and im planning on clearing it and starting from scratch but before i do i want to know where my problem lies.
internet | | Gateway2 | | | RX========== <sw 2960g>==========(Gi0/1)(Gi0/2)Gateway 1 ============>internet | | | Cache server
Now from RX the traffic is out , it may go to Gateway1 router or Gateway2 router
Note that router Gateway 1 has its traffic cached by Cache server. But the Gateway 2 router has not configured to cache its traffic , note that Gateway 1 router has two interfaces connected with sw but Gateway 2 only 1 interface connected to sw .
In the end , if I want Router Gateway 2 to hve its traffic to be cached by cahce server , can I do as the same config which is currently exist in Gateway 1 , or there is different behaviuor ???? Is there new modification on cahce server ?? im using suid cahe based linux .
I will include a brief info about only cache config in gateway1 router
