Create VLAN Problem
Hi, everyone, it's my first time to come here.
Now I have 5406zl(J8697A) VLAN problem, hope you can help me.
Situation:
We have two companys, central company and remote company, they connect by MPLS VPN. Central company server IP: 10.10.168.X , Before create VLAN, default VLAN 6 can access Central server. And create VLAN 2, VLAN 3, VLAN 4, VLAN 5. However, except default VLAN 6, new VLANs cannot access Central server. I will paste my configuration below:
First, paste Router(CISCO 2610) configuration, it connect with ISP and act as CE router.
interface Ethernet0/0
ip address 10.15.0.1 255.255.255.0
half-duplex

interface Serial0/0
ip address 10.0.0.50 255.255.255.252

ip route 10.15.0.0 255.255.0.0 10.15.0.254
Second, paste HP 5406zl(J8697A)configuration, it connect with CISCO Router and act as distrubute layer switch.

So, If enable VLAN 2,VLAN 3,VLAN 4,VLAN 5 can access Central server 10.10.168.X ,what steps can I do ? Thank you !

Re: Create VLAN Problem
you must ask the provider of your mpls network to add the new subnets.
if not the mpls network does not know where to forward these subnets to.

Re: Create VLAN Problem
WOW, so it's trouble to do that ? Any methods can solve the problem without via provider ?

Re: Create VLAN Problem
You won't be able to resolve this without your ISP.
As it is routing (Layer-3) not switching (Layer-2), the MPLS network needs to know what subnets are used on both sides of the link.
If it doesn't you can route from your LAN to the MPLs router, but this won't know it must pass this traffic to the other office.
If you want to be set for future expansion you may consider reserving a larger "supernet" for both offices, so you only need to chnage the MPLS network once.
Like you allready do on your own router.
Apart from this I discovered a possible error in you switces config
>>>
vlan 6
name "VLAN6"
untagged A11-A12,A15-A22,A24
ip address 10.15.0.254 255.255.255.0

exit
ip route 0.0.0.0 0.0.0.0 10.15.5.254
ip route 10.10.0.0 255.255.0.0 10.15.0.254
spanning-tree
<<<
the switch points to itself (10.15.0.254 = vlan-6 address) as gateway for 10.10.0.0 subnet.
this must probably be 10.15.0.1?
