Hi All,
We have a problem on our Network System.
Our customer have 2 segment interface vlan with /23 segment, and all using Metro-E layer 2 :
interface Vlan201
description Voice
ip address 172.27.76.1 255.255.254.0
ip helper-address 169.7.76.71
!
interface Vlan774
description VLAN for 169.7.76.0/23 Subnet for Data, Server, IP Management Devices (All Branch)
ip address 169.7.76.49 255.255.254.0
no ip route-cache
Topology :
Notes :
- All Gateway on the Core (Head Office)
- All Branch Dist Switch using L2 with Trunk Metro-E
- Switch Branch only have interface vlan for IP management
- Gateway interface vlan voice only available on the Core (Head Office)
Issue :
- Branch Bekasi can't call to Branch Ceva
Troubleshooting had been done :
- Create a dummy interface vlan voice on Branch Bekasi and Branch Ceva to check network issue
- Interface vlan voice Branch Bekasi can't ping Interface vlan voice Branch Ceva
- Interface vlan data Branch Bekasi able to ping interface vlan Data Branch Ceva
- Interface vlan voice Branch Bekasi able to ping interface vlan Head Office and other Branch
- Interface vlan voice Branch Ceva able to ping interface vlan Head Office and other Branch
- Try to create interface voice vlan on Distribution Switch (2950) on Branch Bekasi, it was failed. One of them will down (Data / Voice), can't up together
Interface Vlan Voice (dummy) / Data can't up together, one of them will down :
Any advice?
Best Regards,
Rinaldy
