What Is a Site Link Bridge?
u A Site Link Bridge (SLB) contains two or more site
links
l Remember: Site links are networks
u Bridges connect site links
l They work like bridges/routers between networks
u These site links should have at least one site in
common
u Cost for transport is used to make routing decisions;
uses cost to evaluate the "least cost path"
u Knowledge Consistency Checker (KCC) creates
minimum cost routes which can span multiple site
links
u Create multiple SLBs for non-routed segments (VPNs
and so on)
u Default: All links in one SLB
