[cisco-voip] ISR/VG Ethernet redundancy

You should use a loop back and bind everything to in instead of the physical
interface.

If you want Ethernet redundancy you should be able to create an ether
channel down from the router if you are going into the same switch or have
VSS on the 6500. 

If not I have also bridged it into two separate switches using a BVI like
you are looking at.

Subject: [cisco-voip] ISR/VG Ethernet redundancy

Hello everyone

I have a few questions regarding  bridge virtual interfaces and voice
protocols:
- is binding sccp and/or mgcp to a bvi interface supported by Cisco Tac?
- any official configuration guides for this kind of connectivity?
- anyone have this configuration in production and would care to share
his/hers feedback?


My main goal is to be able to use the spare ethernet interfaces on a
router/vg for redundancy but I was surprised by the lack of official
guidance on the subject.

Thanks 
Ovidiu
