This is for an enterprise disaster-recovery scenario. The configuration is simplistic -- http://scotthughes.org/cem-failover
To clarify, I'm talking about Circuit Emulation on ISR routers. I want to emulate analog circuits using a SONET-protected Ethernet VLAN as IP backhaul. The ISR routers are used for various other (different) purposes at all 3 sites (head-end, remote, disaster recovery) and intermixing the routing tables or using route-maps and access-lists would be inconvenient. Running a VRF on a dot1q-tagged interface into the SONET would be a nice way to keep layer-3 separation for the CEM services. I would also prioritize traffic on that VLAN at the SONET level to ensure QoS. I'm open to suggestions about alternate ways to approach this. Obviously, hanging a separate router on a VLAN solely for this purpose is inefficient (and what I'm trying to avoid) -----Original Message----- From: Lars Lystrup Christensen [mailto:[email protected]] Sent: Friday, July 24, 2009 3:36 PM To: Hughes, Scott GRE/MG; [email protected] Subject: RE: [c-nsp] VRF-aware Circuit emulation? Hi Scott, To some degree, this would be rather odd to do as CES is a point-to-point solution and is used to transport TDM traffic. Please clarify why you would do this? ______________________________________ Med venlig hilsen / Kind regards Lars Lystrup Christensen Director of Engineering, CCIE(tm) #20292 Danske Telecom A/S Sundkrogsgade 13, 4 2100 København Ø -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Hughes, Scott GRE/MG Sent: 24. juli 2009 22:06 To: [email protected] Subject: [c-nsp] VRF-aware Circuit emulation?
