uA Site Link Bridge (SLB) contains two or more site links
lRemember: Site links are networks
uBridges connect site links
lThey work like bridges/routers between networks
uThese site links should have at least one site in common
uCost for transport is used to make routing decisions; uses cost to evaluate the "least cost
path"
uKnowledge Consistency Checker (KCC) creates minimum cost routes which can span multiple site links
uCreate multiple SLBs for non-routed segments (VPNs and so on)
uDefault: All links in one SLB
