Hi,
maybe someone can help.
From a carrier I get data with s-tag and c-tag. I have to remove both tags and then I have to prepend an new VLAN Tag.
As example:
First customer: Data from carrier => s-tag 10, c-TAG´s 25,26,27,28 => to my network 25 must be translatet to vlan 100 and 26 must be translatet to vlan 200 (27,28 is not in use in my network).
Second customer: Data from carrier => s-tag 10, c-TAG´s 29,30,31,32 => to my network 29 must be translatet to vlan 100 and 30 must be translatet to vlan 200 (27,28 is not in use in my network).
Third customer: Data from carrier => s-tag 11, c-TAG´s 25,26,27,28 => to my network 25 must be translatet to vlan 100 and 26 must be translatet to vlan 200 (27,28 is not in use in my network).
VLAN translation is typically something you would want to use a CRS for especially since you’re dealing with S-tag and C-tag. Here is a presentation I did last year on VLAN Translation in the CRS (with examples) at the 2015 US MUM in Miami.
Thank´s, but I don´t understand the translation if we have s-tag and c-tag. First I have to drop the s-tag and then I can translate the c-tags or isn´t it.
So how can I do that:
SWITCH (Carrier) → send me s-tag 10 and inside are c-tag 25,26,27 and 28 → I then have to translate 25 to vlan 100, 26 to vlan 200, 27 to vlan 300 and 28 to vlan 400.
And all pacets should find the way back again.
