John, I'm using GLBP round-robin in a specific scenario with "ip routing" as the tracking mechanism, and only in this one specific segment if the network (OSPF elsewhere), with EIGRP as the routing protocol between R1, R2, R3, and R4: -----+---FE----+----- | | R1 R2 | | T3 T3 | | R3 R4 | | ----+----FE---+----- GLBP works very well here for us based on EIGRP routing metrics. There's a very good GLBP config white paper on CCO. No sure if this answers your question, or not.... - ferg -- John Kristoff <jtk@northwestern.edu> wrote: I'm cco-familiar with GLBP. It appears to have essentially the same timing knobs with the ability to actively load balance traffic. Is my assumption that some traffic will not experience any packet loss if it is not using the failed path correct? For anyone who has used this, was the added complexity of this protocol worth it? -- "Fergie", a.k.a.
