My operations manager says "Could you go on-site and configure a new clients new internet connection?" he gives me the info, I make the arrangements and go on-site. As I'm working with the providers tech he says "Do you have a sub-interface confgured for a dot1q VLAN id of 1057?", I say "What?". Anyway my firewall is not capable of dot1q VLAN, so he says "Do you have a Cisco router that can provide the trunking?", I say "Yes, I tink so but not with me". The question is can I use an SR520 between my firewall and the provider demarc to route the VLAN he is talking about? My initial discovery says yes but I am not quite sure of the details on how to achieve this on the SR520. If anyone out their could point me in the right direction that would be great.
