![]() Note 3: Do not forget to recalculate the IdlePC value for the routers once you start this lab in GNS3! Routers R4, R5, R6 are considered to be company edge routers. ![]() Note 2: Routers R1, R2, R3 are considered belonging to the Service Providers offering the Internet/WAN services. You can advertise them as usual networks by configuring each interface as a point-to-point link. Note 1: Loopback interfaces (if any configured) are by default advertised with a /32 mask. After each router reloading, all IP address settings will be automatically restored from the configuration files saved in the CCNP_ROUTE_IPv6 folder. All IPv6 settings will be added during the upcoming labs, depending on the scenarios.Īll lab exercises will be based on these configurations, with a general reloading process after each excercise, so the settings made in one lab will not interact with those made in the next one. You can download this entire GNS3 CCNP lab (including the topology and configuration files for all routers) from HERE.Īll 7 routers in the topology are initially configured with IPv4 addresses. ![]() All routers are Cisco 2691 series, running the c2691-adventerprisek9-mz.124-25c image. Graphical Network Simulator (GNS3 0.8.3) has been used to build this topology. This topology simulates three companies which connect to each other via the Internet. The above diagram will be used for studying all IPv6 concepts in the CCNP ROUTE 642-902 curriculum.
