As others have pointed out, PBR ... * Is a fragile configuration. You're typically forcing next-hop without a [direct] failover option, * Often incurs a penalty (hardware cycles, conflicting feature sets, or outright punting to software), * Doesn't naturally load-balance (you pick the source ranges you route where) However, there are few alternatives in some cases... * If you are using some provider-owned IP space you often must route to that provider, * There may be policies restricting what traffic (sources) can transit a given provider There are few alternatives for the latter cases, unless you split the border across VRFs and assign routing policy on the VRF, which is a global decision across the VRF, and avoids PBR. We're doing a little of both, so I clearly don't take sides :) Jeff
