Carrier supporting Carrier (CsC)




Elements

In this example we will configure Carrier supporting Carrier (CsC)
We have two autonomous systems, AS 100 and 200
Our service providers PEs are R3 and R4 which establishes VPNv4 sessions with R2 and R1, which by in turn establishes VPNv4 sessions between themselves
Our customers are R5, R6 and R9 which in turn will provide R8, R7 and R10 with VPN service by establishing VPNv4 in between
