I have the following setup: PC-----fa0/0--Router1--fa0/1-------------------------fa0/0--Router2--fa0/1-=
--------PC and am trying to get 6to4 tunnels happening between the two routers but to no avail. I believe its something in the route in place but for the life of me I cant spot the error, as the error I get when I try to ping from a PC to the non-directly attached router I get "request timed out" errors It might be a tunnel problem as the destination comes up as "UNKNOWN"
Can someone please help!!! Ive got GRE tunneling and manual tunnels working, but need to test this config (6to4 tunnels) as well.
Configs are as below: Router1#sh run ! version 12.3 service timestamps debug datetime msec service timestamps log datetime msec no service password-encryption ! hostname Router1 ! boot-start-marker boot-end-marker ! memory-size iomem 10 no network-clock-participate slot 1 no network-clock-participate wic 0 no aaa new-model ip subnet-zero ! ip cef ipv6 unicast-routing ! interface Tunnel0 no ip address no ip redirects ipv6 address 2002:C0A8:6301::1/64 tunnel source FastEthernet0/1 tunnel mode ipv6ip 6to4 ! interface FastEthernet0/0 no ip address duplex auto speed auto ipv6 address 2002:C0A8:6301:1::1/64 ipv6 enable ! interface Serial0/0 no ip address shutdown ! interface FastEthernet0/1 ip address 192.168.99.1 255.255.255.0 duplex auto speed auto ipv6 enable ! interface Serial0/1 no ip address shutdown ! ip http server no ip http secure-server ip classless ! ipv6 route 2002::/16 Tunnel0 !
