Configure Trunk carrying same Vlans on two separate uplinks on Cisco 3845

Hi,

I need to carry 2 vlans(x & y) in a trunk to two separate redundant devices uplinked to Cisco 3845 on Fa1/0 and Fa1/1. I know I can create sub-interfaces on one of the uplink interfaces(i-e Fa1/0) with 2 distinct 802.1q vlans(Fa1/0.x & Fa1/0.y). But is there a way I can carry same vlans(x & y) trunked to my 2nd redundant device uplinked on 3845 from Fa2/0 ? If not then how should I get the 2nd redundant device uplinked to this 3845 router.

Any tips.. ?

Thanks for your help and suggestions.

IF both links are going to the same device then you can create a Layer 3 Etherchannel

No there are going to two different devices for redundancy. I might have to use IRB I guess but not sure if there is going to be any downside since we havn't used that type of solution in our enviornment before.

Thanks for replying.
