Lab 209 - IPv6 Over IPv4 Using GRE Tunnel

Lab 209 - IPv6 Over IPv4 Using GRE Tunnel
Di Posting Oleh : Simple Learning
Kategori : IPv6

Prerequisites: CCNP level skills.

Note!
If interfaces have not been configured with IPv6 addresses yet, use fc00:1:1::/64 as the network-ID and ::x, as a host ID (where x=router-ID).

Topology

Pic 1. IPv6 and IPv4 Topology Diagram.
Task 1
Configure IPv6 and IPv4 addresses, RIPng and EIGRP AS 1, according to the topology diagram (pic. 1 above). On R1 and SW4, advertise their loopback0 interfaces in EIGRP.

Task 2
Configure R1 and SW4 in such a way that IPv6 subnet in VLAN 215 can reach IPv6 subnets in VLANs 7, 9, 27, 79, and 99. Ensure that the tunnelling method can carry packets other than IPv6 (for instance IS-IS based on CLNS protocol). Tunnel should be based on the R1's and SW4's most stable interfaces. You can add two new IPv6 addresses to make the solution work.

Solution

Task 1
Configure IPv6 addresses, RIPng and EIGRP AS 1according to the topology diagram (pic. 1 above). On R1 and SW4, advertise their loopback0 interfaces in EIGRP.

Task 2
Configure R1 and SW4 in such a way that IPv6 subnet in VLAN 215 can reach IPv6 subnets in VLANs 7, 9, 27, 79, and 99. Ensure that the tunnelling method can carry packets other than IPv6 (for instance IS-IS based on CLNS protocol). Tunnel should be based on the R1's and SW4's most stable interfaces. You can add two new IPv6 addresses to make the solution work.

Step 1 - RIPng Between SW1, SW3, and SW4.
