I've a client who have a T1 and want to add a 100mb/sec microwave link to my POP (Fast Ethernet-to-microwave bridge). They've one router, a 36xx, with both Fast Ethernet and an internal Cisco DSU. The microwave portion is a breeze, but other aspects are giving me pause. At my POP, I have a Catalyst 5509 doing MPLS with a 7206 as the MLS-RP. The 7206 has a serial interface, and already has an external DSU plugged into it. The 7206/Catalyst combo is part of my OSPF backbone, area 0. What's the best way to set up load-balancing across these unequal links? I've done OSPF with unequal paths using multiple routers, same with EIGRP, but I'm unsure whether OSPF and/or EIGRP will support seeing two distinct interfaces in the same router or router/switch combo as being distinct neighbors. With EIGRP, it's possible to load-balance unequal paths so that no traffic goes through the higher-cost path unless/until the lower-cost path goes down; does this work if both paths happen to be attached to the same router? I have total control of both routers, so I have no problem making the customer's router a stub area in my OSPF IGP, or in letting their router participate in EIGRP. Any advice/comments/pointers would be greatly appreciated. -- ------------------------------------------------------------ Roland Dobbins <[email protected]> // 818.535.5024 voice |
