TSHOOT on IPv6 GRE Tunnel

Hi ! everyone on today we are going to learn about ipv6 GRE tunnel with explanation shown in topology with the given below screenshot.

Problem: Loopback address on R1 (2026::111:1) is not able to ping the loopback address on DSW2 (2026::102:1).

Configuration of R3:
!
interface Tunnel34
 no ip address
 ipv6 address 2026::34:1/122
 ipv6 enable
 ipv6 ospf 6 area 34
 tunnel source Serial0/0/0.34
 tunnel destination 10.1.1.10
 tunnel mode ipv6
!

Configuration of R4:
interface Tunnel34
 no ip address
 ipv6 address 2026::34:2/122
 ipv6 enable
 ipv6 ospf 6 area 34
 tunnel source Serial0/0/0
 tunnel destination 10.1.1.9
!

Answers:
1: R3
2: Ipv4 and Ipv6 Interoperability
3: Under the interface Tunnel34, remove ‘tunnel mode ipv6’ command

Therefore, we have studied in this lab session about ipv6 GRE tunnel configuration with the help of packet tracer version 7.1
