Hi All,
I am configuring a trunk link betweem cisco 7206VXR and Cat6509.The link is up and connected.The connection between router and switch is on the same Vlan 200.I have tried using access mode but no luck.Would like to know whether my config is Ok?
But am not able to ping the sub-interface of the router from Cat6509.
Can anyone guide me with the configs.I am testing a VRRP scenario,so there are other switches in the topology.
Thanks in Advance
Cisco7206VXR
-------
interface FastEthernet4/0.200
encapsulation dot1Q 200
ip address 10.0.0.2 255.255.255.0
vrrp 4 timers learn
vrrp 4 ip 10.0.0.1
vrrp 4 priority 254
end
Cat6509
--------
interface GigabitEthernet1/1
switchport
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 200
switchport mode trunk
no ip address
end

Could you provide the vlan config. of 6509 and also the show trunk / vlan in both equipment ? Thx.
If you are using IOS newer than 12.1(3)T in 7200. Try below command if VLAN 200 is native VLAN.
interface FastEthernet4/0.200
encapsulation dot1Q 200 native
Hope this helps.

Thanks Jack for your quick response.
My 7206VXR is using IOS 12.0(18)S1, will upgrade the IOS to enable the native keyword.
I will give you the whole scenario for your quick understanding.Should I need to add a new vlan in the cat 6509 as native vlan other than Vlan1?

Hi Friend,
When you say you are not able to ping from your 6509 to the router sub intrerface for vlan 200 can you please confirm what all layer 3 interfaces you have on cat6509?
WHY I am asking this is because I believe you are having routing for vlans on your router and you have only allowed vlan 200 on that trunk link so if you will ping from cat6509 the source ip of ping packet if it will be something else then vlan 200 the ping will not work. So if you allow other vlans on your cat6509 trunk it should ping.
Also I believe in your same setup if you connect any host on vlan 200 on any physical layer 2 port you should be able to ping your vlan 200 sub interface.
Please update the result.

Beno,
I see some problems with your config
1) You don't have Layer2 VLAN created in the 6509. I can confirm this with this command.
Port Vlans allowed and active in management domain
Gi2/1 none
Can you post the output from typing 'show vlan' on this switch ?
2)
From the config you posted, it seems you are using the 6509 ports as L3 ports but on the portion that does not work, it's acting like a L2 port. If you decide going with L2 configuration, you need to create a SVI for VLAN 200 and assign an IP to it.
3) The trunk on G1/1 is down
sh int switchport
Name: Gi1/1
Switchport: Enabled
Administrative Mode: trunk
Operational Mode: down
Can you please post the entire config ? It would help troubleshooting.
Thanks

Q2>>
Do I need a SVI interface for this?
Anyway I tried creating a SVI interface as
int vlan 200
ip address x.x.x.x
But still am not able to ping 10.0.0.2
Q3>>
Entire config is attached.
I am able to ping from Cat6509-1 to 10.0.0.5,but not to 10.0.0.2.I think am wrong with my configs,can you please help me out?
Thanks,
Beno

Do you mean when you use SVI interface, you can ping from 6509-1 to 10.0.0.5 but not .2 ?
What is the original IP address in 6509-1 ?
According to the entrie config, there is no IP config for 6509-1. Please advise.
Moreover, you need to create VLAN 200 in switch if you are using trunk.
Moreover, are you sure to use 192.x subnet in VLAN 200 that same with subnet 10.x ?

Thanks Everyone who has assisted me.
It works without any SVI interface on 6509-1,able to ping the sub interface.It was my routers problem did a reload,everything got fixed.
Was a good learning from all you guys about various concepts.
I will start this post again for any other redundancy issues.
Jack,
No I did not use SVI interface,it was suggested by one of the Netpros.
You are correct there are no IP configs for 6509-1
Vlan 200 is created in 6509-1
Yes,I can use 192.x subnet in VLAN 200 that same with subnet 10.x

Thanks for the update. And you carried the most important action is to reload the equipment. It is also one of the troubleshoot technique. :)
