6500 in different VTP

[mohammed.misbahuddin]

Hi,

I have two VSS (6509) running in different location, actually two sites they merge. so some of the servers moved from site B to site A but the default gateway is in site A. unfortunately the servers moved they cannot communicate to the default gateway which is on site B, to re-mediate what we have done is create another svi vlan 805 on site B and a route is configured from site B to site A pointing to default gateway. 

Can somebody explain me why is this a problem when both the sites are in trunk mode, any suggestion for this is highly appreciated.

Regards

Mohammed

If they are running as a VSS pair, the default gateway for the Vlans should be on whatever is the active switch.

Are you saying the Active Switch is Site A but the clients are physically in Site B and they cannot access the default gateway?

Can you post the config?

Thanks

VSS1 (Pair of 6509)- Site A

vtp= ABC / Transparent

VSS2 (Pair of 6509) - Site B

vtp= XYZ / Transparent

Trunk port between Site A and Site B

====================================================

Site B = SVI vlan 805 = 10.21.5.1/24

Site A = Server = 10.21.5.89/24

So server at Site A is not able to ping default gateway which is in Site B.

What is the config on the Trunk between the two sites?

[mohammed.misbahuddin]

switchport

switchport mode trunk

swtichport trunk allowed vlan 805,xxxxxxx

no shutdown

805 vlan exist on both Site A and Site B
