In general, interfaces facing toward to the network core, or toward 

routers supporting the Network Discovery protocol, are configured as 

trusted interfaces.

◆

RA messages received from a trusted interface are added to the prefix 

table and forwarded toward their destination.

◆

NS messages received from a trusted interface are forwarded toward 

their destination. Nothing is added to the dynamic user binding table.
