Hi
I'm setting up this type of tunnels but I can't find any good source of information about how to do it. As far as I know we need a routing protocol that provides you with the next hop in order to reach the IPv6 netwotk, for example BGP, but in my topology it is going to be easier, just 3 routers connected to a switch.
I have an IPv6 loopback in each of them and ethernet connections using IPv4 addressing, here are the configs:
/////////R1/////////
interface Tunnel0
no ip address
no ip redirects
ipv6 ospf 1 area 0
tunnel source Ethernet0/0
tunnel mode ipv6ip auto-tunnel
!
interface Loopback50
no ip address
ipv6 address 2001:1:1:1::1/64
ipv6 ospf 1 area 0
!
interface Ethernet0/0
ip address 10.0.0.1 255.255.255.0
half-duplex
router ospf 100
log-adjacency-changes
network 10.0.0.1 0.0.0.0 area 0
/////////R2/////////
interface Tunnel0
no ip address
no ip redirects
ipv6 ospf 1 area 0
tunnel source Ethernet0/0
tunnel mode ipv6ip auto-tunnel
!
interface Loopback50
no ip address
ipv6 address 2001:2:2:2::2/64
ipv6 ospf 1 area 0
!
interface Ethernet0/0
ip address 10.0.0.2 255.255.255.0
half-duplex
router ospf 100
log-adjacency-changes
network 10.0.0.2 0.0.0.0 area 0
/////////R3/////////
interface Tunnel0
no ip address
no ip redirects
ipv6 ospf 1 area 0
tunnel source Ethernet0/0
tunnel mode ipv6ip auto-tunnel
!
interface Loopback50
no ip address
ipv6 address 2001:3:3:3::3/64
ipv6 ospf 1 area 0
!
interface Ethernet0/0
ip address 10.0.0.3 255.255.255.0
half-duplex
!
router ospf 100
log-adjacency-changes
network 10.0.0.3 0.0.0.0 area 0
!
I'm doing something wrong but don't know what...
any idea?
thanks!
