i coudnt up load the image , please how i can do it
السلام عليكم ورحمة الله وبركاته
, please see the image
in our company we have site x , now connected via link1 , but becuse this link sometimes becom down , we want to use also link 2 , we want them work at same time load balance , and if not possible (i think it is possible ) just backup it is ok , if one fail the other one becomes up .
i tryed to think about , GLBP and HSRP , but when i do this planning on paper i find the idea not applicable
maybe i did mistake , so please i want your experince with me , , , and finally if those protocols cant be done , what the best of dynamic routing protocols OSPF&EIGRP, , , ,, and it is noticable that in our compay still not using dynamic ,, we use static .وجزاكم الله خيرا

بص ياباشا الحل اللى انا من وجهة نظرى الضعيفة شايفه ان تشغل رواتنج بروتوكول زى ال EIGRP حلو وبعدين تعمل ستاتيك راوت ل X من الانترفيس اللى خارج للرواتر X وهو كده كده هيسجل عنده ان فى مسار تانى لاكس من خلال السويتش بس هيستخدم الاستاتيك لانه الاكثر مصداقية والتانى يكون باك اب لو لينك وقعت يفض الراوتر عارف انه له مسار تانى عن طريق الراوتنج بروتووكول
لو كلامى فى حاجة غلط ياريت حد يصحح
وتحت امرك حبيبى
بارك الله فيك
i will see this solution ,, but what about load balance between the two links
thanks
السلام عليكم
with eigrp you can make load balancing up to six free loop link (with variance multipler command)
but in your diagram you've looped linkes
السلام عليكم
شوف هذا اللنك

thanks
what about GLBP and HSRP
and OSPF as a last solution (1-load balance , second redundancy) n
thank you
You can accomplish almost all HSRP configuration in the router's Interface Configuration Mode using the standby command. Let's look at the steps I took to configure the network shown in the diagram.
For Router 1:
Configure the IP address on the Ethernet interface.
Configure the standby IP address.
Configure standby preempt. (With preempt, Router 1 will always be the primary router as long as it's available.)
For Router 2:
Configure the IP address on the Ethernet interface.
Configure the standby IP address.
Configure standby priority to be less than 100. (In this case, it's 99.)
Now, let's look at the configuration for our sample network.
Router 1
(show running-config output)
interface Ethernet0/0
ip address 10.1.1.1 255.255.255.0
standby ip 10.1.1.3
standby preempt
Router1# show standby
Ethernet0/0 - Group 0
State is Active
2 state changes, last state change 00:00:29
Virtual IP address is 10.1.1.3
Active virtual MAC address is 0000.0c07.ac00
Local virtual MAC address is 0000.0c07.ac00 (default)
Hello time 3 sec, hold time 10 sec
Next hello sent in 0.692 secs
Preemption enabled
Active router is local
Standby router is 10.1.1.2, priority 99 (expires in 8.097 sec)
Priority 100 (default 100)
IP redundancy name is "hsrp-Et0/0-0" (default)
Router1#
Router 2
(show running-config output)
interface Ethernet0/0
ip address 10.1.1.2 255.255.255.0
standby ip 10.1.1.3
standby priority 99
Router2# show standby
Ethernet0/0 - Group 0
Local state is Standby, priority 99
Hellotime 3 sec, holdtime 10 sec
Next hello sent in 1.014
Virtual IP address is 10.1.1.3 configured
Active router is 10.1.1.1, priority 100 expires in 7.159
Standby router is local
4 state changes, last state change 00:02:02
Router2#
You can use the show standby command when in Privileged Mode to check the status of HSRP. This command tells you which router is active and which is standby, as well as a number of other statistics.
On the PC, the default IP address should point to 10.1.1.3—not either of the routers. This way, if one of the routers goes down, the other will take over. And you may even be able to use this redundancy to take production routers down during the day because the HSRP failover time is less than 10 seconds.
HSRP is a valuable tool for ensuring high availability and router redundancy. Of course, there are also several HSRP options that I didn't address in this article. For more information, check out the Cisco HSRP FAQ.
You can configure GLBP in Interface Configuration Mode. Here's an example of a basic configuration on a single router:
Router(config)# interface FastEthernet 0/0
Router(config-if)# ip address 10.1.1.5
Router(config-if)# glbp 1 ip 10.1.1.1
Router(config-if)# glbp 1 priority 150
Router(config-if)# glbp 1 authentication md5 key-string 0 MySecretPassword
Note: Cisco didn't introduce GLBP MD5 authentication until Cisco IOS version 12.3(2)T
