We're going to be deploying 20-30 VG224s at each of our hospitals to support patient room analog phones. We've got an IPTel services block consisting of 2 4948's L3 off of the core. L2 trunk and L3 eigrp adjacency (eigrp) between the 2 4948's. We were initially going to do redundant links on the VG224's with EIGRP & loopback on the VG224 but I recently ran into a (non-cisco) article talking about configuring IRB on the VG224 to create a bridge group and BVI on the VG224 to assign the IP address to. To me it seems simpler & cleaner than configuring eigrp (with stub plus distribute list w/ prefix list, etc) on hundreds of vg224's across the org.
Has anyone configured vg224 redundancy in this manner? Good, bad or indifferenct experience? Opinions? We can't seem to get any solid opinion out of Cisco on the matter.
