1. traceroute ipv6 example where network connectivity is good:
DES-7200# traceroute ipv6 3004::1
< press Ctrl+C to break >
Tracing the route to 3004::1
1 3000::1 0 msec 0 msec 0 msec
2 3001::1 4 msec 4 msec 4 msec
3 3002::1 8 msec 8 msec 4 msec
4 3004::1 4 msec 28 msec 12 msec
As you can see, to access the host with an IP address of 3004::1, the network
packet passes throuth gateways 1 to 4 from the source address. Meanwhile,
you can know the time that the network packet spennds to reach a gateway.
This is very useful for network analysis.
2. traceroute ipv6 example where some gateways in a network are not
connected:
DES-7200# traceroute ipv6 3004::1
< press Ctrl+C to break >
Tracing the route to 3004::1
1 3000::1 0 msec 0 msec 0 msec
2 3001::1 4 msec 4 msec 4 msec
3 3002::1 8 msec 8 msec 4 msec
4 * * *
5 3004::1 4 msec 28 msec 12 msec
As you can see, to access the host with an IP address of 3004::1, the network
packet passes through gateways 1 to 5 from the source address and there is
failure in gateway 4.
