cisco 2811

f0/0.10 = 192.168.10.1/24

f0/0.20 = 192.168.20.1/24

cisco 2950 Swtich:

f0/0 = switch port trunk

f0/1 = switch port access vlan 10

f0/2 = switch port access vlan 20

Hello Ananth,

To my knowledge we can not configure transprent mode with trunking, What you should do is create multicontext transparent mode and then bridge the VLANs

Hello Ananth,

You can make this happen using the firewall on multiple context or using the new feature ( bride groups)

Here are the links for both options:

Any other question..Sure.. Just remember to rate all of my posts

Hello ALL,

Looks like Im now plagued with a similiar issue. I have to congigure an ASA in transparent mode and am a little unfamiliar with this aspect of it from the 5520 level. Im am familiar with doing this on the 5505 As it is semeingly easier. I just dont know if I NEED sub interfaces referencing the vlans in question. Or if I need to just add the required inside/outside interfaces to a BVI and give it an IP address

Any assistance offered would be greatly appreciated.

Thank You,

Hameed
