Inter VLAN doesnt work on cisco7600

Firuz Azimov

Hi

I configure intervlan on cisco 7613 (2vlans on one port).

There are 2 vlans (vlan 10 and 20)

Users in vlan 10 cannot communicate with users in vlan20. 

 

I did successfully this configuration in many routers. But it doesn work in cisco7600 on ES+ card.

 

Maybe someone know how to resolve this issue.

 

Thanks.

Any help appreciated.

Please post you configs from the router and the switch.

 

CF

Cisco 7600 (acts like router)

interface TenGigabitEthernet12/1
 description MAIN---CONNECT
 switchport
 switchport trunk allowed vlan 666,777
 switchport mode trunk
end

interface Vlan777
 ip address 192.168.101.2 255.255.255.252

ip wccp 80 redirect in

interface Vlan666
 mtu 9000
 ip address 192.168.243.105 255.255.255.252
 ip wccp 80 redirect in
 ip flow ingress

Huawei (Switch)

interface GigabitEthernet4/1/1
 stp disable
 flow-interval 30
 port link-type trunk
 undo port trunk permit vlan 1
 port trunk permit vlan 666 777

 

 

 

 

  Are the layer 2 vlans created on each side of the connection.  On the Cisco side do a show vlan and make sure both show active .  Cant help you with the Huwaei switch haven't worked on those but check that side also . 


BT#show vlan id 777

VLAN Name                             Status    Ports
---- -------------------------------- --------- -------------------------------
777  test_0355                        active    Te12/1

BT#show vlan id 666

VLAN Name                             Status    Ports
---- -------------------------------- --------- -------------------------------
666  VLAN0666                         active    Te12/1

Both vlans are active.

Users on vlan 10 and 20 can ping their default gateways but cant ping each other.

 

Maybe this restriction only in 7600 ES+ cards ?

Hello

 

is ip routing enabled on the core switch

Does the access swich have a default-gatway or default route to the core!

 

sh ip route

sh int trunk

ip routing is enabled by default on 7600.

I changed vlan 666 to 778. Hope this information helpful

Your SVIs are using /30 subnets but you are talking about users in each vlan.

So is it just one user per vlan ie. the other available IP address or do you have multiple users.

Jon

Yes you are right. In each vlan one user.

any update guys?

If vlan 666 connects to port 12/1 and vlan 777 connects to port 12/2 the can ping each other.

Sounds like a trunking issue.

Can you post from the 7600 a "sh int trunk" (presuming that is the command ie. same as 6500) and the equivalent from the Huawei switch.

So basically you have the two clients connected to the Huawei and then that is connected to the 7600 with a trunk.

Is that correct ?

Jon
