  1. Passed CCIE Routing and Switching

    In Lab 5, i have 2 doubts... HSRP timers by default is 3 sec and 15 hello packets (1x5). Question says standby will take up active role in a second if 5 hello packets not received. Solution given is standby 0 timers 3 16. I feel the solution could be standby 0 timers 4 20. This is because we add one sec and even hello packets need to be added. Zone based Firewall. Both rules are just pass and pass for source and destination. Then why we are force to put zone B facing BB while zone A facing the networks. I feel in this situation zone A or B could work because both have same rule pass and pass. Please assit. mohdsangey@yahoo.com
  2. Passed CCIE Routing and Switching

  3. VTP

    Hi, I have another question. i configured spanning-tree between port 15 and 7 with cost 1 and 10 simultaneously. So port 15 is root and port 7 is in block state. Now surprising thing is that i can see traffic about 1.5mb on port 7 while its in block state. From my knowledge if port 7 is in block, there shouldn't be any traffic or less traffic 1k for hello packets only. Please assist.
  4. Automatic redundacy

    Hi, i have 2 cisco layer 2 switches 2950. Cables from both switches are connected to D-Link switch. Now i want to configure one switch as primary and sec and backup but it should be automatic redundacy. i have tried with STP, but STP works only locally when both cables connect to same switch. Please assist.

    Hi, I have configured IPs into different vlans and all are reachable except antenna IPs which are between trunks. Where should i configure gateway of antenna IPs as they are trunk and not under vlans. Please assist.
  6. VTP

    I have no issue with this configuration... just asking if there is way to bypass vtp for some interfaces only.
  7. VTP

    Hi, So do you mean, that is not possible at all. Actually i have switch in vtp client mode. i need 1 - 2 interface with vlan 20 which is not under vtp as separate.
  8. VTP

    Hi, I am little confused here. How can i disable STP as below are the options. Second my switch is vtp client mode, how can i be able to create vlan while only server has authority to create vlans. int fa0/6 (config-if)#switchport access vlan 20 %VTP VLAN configuration not allowed When device is in CLIENT mode. (config-if)# int fa0/6 (config-if)#no spanning-tree ? bpdufilter Don't send or receive BPDUs on this interface bpduguard Don't accept BPDUs on this interface cost Change an interface's spanning tree port path cost guard Change an interface's spanning tree guard mode link-type Specify a link type for spanning tree protocol use mst Multiple spanning tree port-priority Change an interface's spanning tree port priority portfast Enable an interface to move directly to forwarding on link up stack-port Enable stack port vlan VLAN Switch Spanning Tree

    Dear All, switch is configured in vtp mode client. I want to configure fa0/23 - 24 without vtp. Is it possible??? i mean to those two interface should be member of vlan 20 which is not in vtp. Please assist.
  10. Avoid loop in network infrastructure

    Hi Guys, I feel the problem is cisco switch which i am planning to change. This is the switch connected to router directly. I will let you know the output and explain you entire situation. I erased startup of the cisco switch 2960, crypto config was not there. But when i restart the switch it appears again as shown below.

  11. Avoid loop in network infrastructure

    Hi, I have one more interface from router to my switch. So it means two cables from router to switch.Second int configuration is as follows: int g0/3 ip address Still investigating where could be the problem.
  12. Avoid loop in network infrastructure

    Dear Sir, Please can you suggest what should i check in the configuration. i have got configuration of 10 pages.
  13. Avoid loop in network infrastructure

    I have 10 switches with VTP client. They all synchronize without any problem.
  14. Hi, I experience Loop problem in my network infrastructure. To avoid that i configured each network in different vlans by using router on a stick. But unfortunately loop still exist and affects entire network. Can anyone assist how to solve this issue. Cisco Router Config: int g0/0 no ip address int g0/0.10 encapsulation dot1q 10 ip address x.x.x.x int g0/0.20 encapsulation dot1q 20 ip address y.y.y.y Cisco Switch 2960 Config: int fa0/0 switchport mode trunk int fa0/10 switchport mode access switchport access vlan 10 int fa0/20 switchport mode access switchport access vlan 20 vtp mode server vtp version 2 vtp password xxx vtp domain aaa Remarks: VTP works perfect without any issue. Loop Testing: int fa0/21 switchport mode access switchport access vlan 20 Practical : Connected D-Link switch to port No. 21 and created same cable both interfaces of the D-Link switch. This loop even affected vlan 10. Actually separate vlans, broadcast are prevented, but in my case broacast affects. Regards Mohamed Skype: mohamedsangey
  15. Hi. Already sorted out by replacing layer 2 to layer 3 in the configuration.
