Hi, my company is deploying a MAN for a new office using a 100Mbs L2 link and a 34Mbs L2 link for backup. Infrastructure includes Cisco IPT and management wants to use larger link for data and smaller one to voice, keeping QoS on both of them and being redundant against each other.
Global policy states we use EIGRP locally and BGP for intersite connections (intersite conns are provided by global MPLS network and carrier provided routers redistributing BGP and EIGRP routes back and forth).
I am allowed to use BGP locally using another AS for this tasks, which looks to me a very good solution. Just wondering if someone has another approach/idea for that task. Load balacing thru EIGRP is a fallback so I am not considering it for now.
The L2 connections will go from a 3750 Catalyst to a 4507 Catalyst switch. Both them with 12.2 EMI and Enterprise images. Thanks a lot.
Thanks for quick reply. I meant, carrier will provide us what they call LAN-2-LAN in Brazil, not sure of other market names. I will have both switchports direct on their UTP cables, so I can use switch ports as L2 or L3. If L2, we could partition STP instances using some of its variations. But I would not want to have STP going back and forth in the MAN link. I don't use BGP today at these links but we are considering doing that.
We are pleased to announce availability of Beta software for 16.6.3.
16.6.3 will be the second rebuild on the 16.6 release train targeted
towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are
looking for early feedback from customers befor...
