Aug 9, 2013 · The tunnel endpoint terminates (removes) the tunnel and sends on the client's IPv6 traffic to any IPv6 Server on the internet. This allows us to run IPv6 on our DMVPN tunnel interfaces while using IPv4 (or IPv6) on the underlay network. 1255. May 6, 2010 · TSP allows IPv4 or IPv6 packets to be encapsulated and carried over IPv4, IPv6 or IPv4 NATs. com is an IPv4 address and the ssh connection goes over IPv4. 1 tunnel mode ipv6ip Example: IPv6 over GRE IPv4 Tunnel Example: Configuring CE1! ipv6 unicast-routing ipv6 cef! interface Ethernet0/0 no ip address ipv6 address 2001:DB8:2:1::1/64 no shutdown exit!! ipv6 route 2001:DB8:2:2::/64 2001:DB8 It will convert the IPv4 address in hexadecimal and give you the correct IPv6 tunnel prefix with the show ipv6 general-prefix command. Tunneling encapsulates IPv6 packets within IPv4 packets (or vice versa). Solution Topology: The tunnel entrance is router F 20. 2(33)SRA 12. 0 exit! ipv6unicast-routing routerisis net49.
