We have 7200 router on which two links from different ISPs are terminated. Right now one link is primary and the second one is redundant.Now we have procured our own IPs and plan to run BGP with both the service provider. Can we configure GLBP on the router so that both the links can be simultaneously used and when one goes down the other takes the full load.
View 2 RepliesWhich is the best way of creating GRE Tunnels on a GLBP enabled router? I actually have two 3845 with GLBP configured as our gateway routers, and need to create gre tunnels to branches.The plan is to use the GLBP virtual IP as the Tunnel Source address and the branch WAN interface as the tunnel Destination address, how do i handle the Tunnel IP address? Do i create the same Tunnel on both gateway routers and have a glbp virtual IP address for the Tunnel Interface as well?

When trace route from LAN PC show that traffic is only taking via single router. LAN gateway is defined as ASA inside address and in ASA a default route pointed to GLBP address.

I have 2 nexus 7000's each currently running HSRP, All the SVI's are in 2 HSRP groups, my question is how many SVI's can be asocaited with 1 GLBP group? Does the Group have to be different for each VLAN? How many GLBP groups can be configured on the Nexus?
View 5 Replies View RelatedI'm in the process to install two 4948E switches. I will be configuring GLBP and wanted to get some guidelines on configuring GLBP and EIGRP:
- First question is like HSRP I'm configuring it on both swithches like this:
Switch 1:
interface vlan 5
ip address 10.1.5.249 255.255.255.0
glbp 5 ip 10.1.5.1
glbp 5 priority 110
glbp 5 preempt
glbp 5 authentication md5 key-string xxxxxx
[code]....
- Second question is about EIGRP, when I configure EIGRP on the main switch that is AVG with the following commands, will I also have to run the same commands on the second 4948 E too?
router eigrp 10
network 10.1.5.0 255.255.255.0
Is there a guide for a migration of the GLBP to VSS between to 6500 Series SW ?

So I have 2 routers (cisco 3640) that each go to their own ISP and then back to the same switch. I have setup ospf and glbp, and now have pretty good redundancy. If either internet connection or routers go down everything is still golden.
So I was thinking that if an interface went down then the router would not be load balanced with glbp which got me thinking whats the best way to get interface redundancy (and I was going to add a 2nd switch with the second interface).
1) Setup BVI on the 2 interfaces.
2) Setup a 2nd interfaces (on each router), I would have to split the subnet, for instance: [code]then the machines could be on the subnet 192.168.0. 0/23 and setup glbp for 1 ip across all 4 interfaces (I'm not even sure if you can do this but think it would work).
3) Is there a way to utilize etherchannel or anything like this
A negative to option 2 would be that if 1 of the interfaces went down, all the sudden 2/3 (or so) of your traffic would be going through 1 router.
I have two routers at our core data center, a 3845 and a 3640. These are configured with GLBP. There are 4 remote sites:
Site #1: One T1 link to the 3825
Site #2: One T1 link to the 3825, and One T1 link to the 3640
Site #3: One T1 link to the 3825, and One T1 link to the 3640
Site #4: One fractional T1 link to the 3825, and One T1 link to the 3640.
My question regards site #4. If i understand correctly, GLBP works on the premise of "host" balancing, and not true "load" balancing. The reason I ask is that the large majority of our WAN traffic is from our Exchange server to our remote sites. In the case of site #4, our exchange server is sending traffic on the fractional T1. Is there any way with GLBP to either split this traffic from a particular host across two links in a round-robin fashion, but leave other hosts to travel wherever the router sends them, or, to force at least our exchange server to use the full T1, rather than the fractional?
I've read up on the weighting mechanism, and it appears that tracking an interface has nothing to do with bandwidth use. If I understand correctly, if I were to track the Site #4 PPP to the 3640, and give a weight of 10 to glbp on there, it would really only take affect if the interface is down. It will have nothing to do with host AVF election.For the record, exchange traffic is constant to this site, so there is no chance for the host connection to reset and potentially elect to use the larger pipe. I would like to "tweak" this to make better use of available bandwidth.
I have problem in the configuration of Cisco ASA 5520, IOS version 8.4. The connection is as follows: LAN network--> Firewall --> Routers with GLBP with virtual ip address. the clients can not ping the virtual interface of the GLBP group, but I can ping it from the firewall, and I can ping the clients from the firewall, I checked the packet tracer it gives :
Phase: 7
Type: NAT
Subtype:
Result: DROP

I have a CISCO 851W router in the garage that I want to connect to my Linksys router in the office, which is connected to the internet.The 851W is connected from it's WAN port to Lan port 1 of the Linksys router. Now, currently that ethernet cable is a straight-through cable. Does it have to be crossover? If so, I can fix that.

How do i configure this details in the router and access the internet in my devices.i want the network to be in 192.168.1.0 to 254.
I need to front-end my ISP's router with another, giving me a DMZ. I have bought an EA2700 for this but I can't find how to configure it.
I plan to have the DMZ network as 10.1.2.0/24, with the ISP's router at 10.1.2.254 and the EA2700's "upstream" connection as 10.1.2.1. The internal network (where most of the clients reside) will then be 10.1.1.0/24, with the EA2700 itself at 10.1.1.254 and a DHCP range 10.1.1.100 upwards.
On the basic setup screen I've set the Internet connection type to fixed IP, 10.1.2.1; I've set its default gateway and DNS1 as the ISP's router at 10.1.2.254. Then further down in network setup I've entered the *internal* address 10.1.1.254 and set the DHCP range and netmask appropriately. I'm getting the error message "The IPv4 address and gateway are not in the same subnet mask". But the only gateway I've entered is the one by which the *EA2700* knows how to route upstream traffic, viz the ISP's router at 10.1.2.254. Or am I misunderstanding?
More fundamentally, can the EA2700 be configured in this way?
configuring my Cisco 2951 router. There are three routed interfaces that I need to configure: one for the internal LAN, the second for another private subnet that connects to a Data Centre and the third for the WAN connection. I have configured the Ge0/0 interface as the LAN interface with the internal network 10.17.0.0/24. I have also configured my WAN interface Ge0/1 for internet connectivity. Now, I need to configure the third interface Ge0/2 that will connect to the Data Centre. This will be a private point to point switched ethernet link. The Data Centre will host a secondary domain controlller. So, I want it to be on the same network as the internal LAN, i.e., 10.17.0.0/24. I want to be able to see all other devices that will be located at the Data Centre just like I would see all devices connected to the internal LAN.The problem I am facing is that Cisco 2951 does not allow me to configure two routed interfaces to be on the same subnet. Is there any way to work around this problem and configure both the internal LAN and the Data Centre private network to be on the same subnet.

However, I am having trouble getting the internal AP to bridge to the router properly. It is my understanding that the Wlan-GigabitEthernet is the internal interface connecting to the AP and the BVI1 together. I can't ping any ip address on the router side from the ap and the radio is active and we can see it but it seems that it doesn't give an ip address. [code] Is it a VLan issue or an ip issue but I could use a second opinion. I've included both configurations.

The ISP provides us with IP Addresses via DHCP. Our public address is NOT static so the interface on the DSL Module needs to be provisioned to get a DHCP address with a CLASS C License.The IP address of the Router should be 10.0.0.10 subnet=255.255.255.0The LAN Clients need receive their IP address via DHCP EXCEPT for a range of 100 addresses. The lan Clients only need about 40 DHCP addresses.ONE of the Lan Clients (10.0.0.3) needs to have ports 25, 1723, and others forwarded to it.
