Hi, on the same line i have few more doubts. pls help me to solve this.
I have 5 vlans namely data, voice , video and CCTV. Packet coming out of access switch will go to SVI and then come to FWSM as firewall-group has been configured. Now I want to integrate this LAN to my MPLS cloud. I have created two vrf (one for voice/data and video) and another for CCTV and importing and exporting to all remote sites. My question is how does FWSM behave when default gateway is on MSFC svi (i have created dot1 q interfaces on svi and assign vrf forwarding to respective interfaces). Since on svi i have configured vrf forwarding, will FWSM understand the firewall-group in this case? any help is greatly appreciated....
