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
