ipv6 route and show interface tunnel commands as shown in the following:
Displaying tunnel information
For example, to tunnel information for tunnel 2, enter the following command at any level of the CLI.
Brocade# show ip-tunnels 2
IPv6 tnnl 2 UP : src_ip 10.211.2.1, dst_ip 10.212.2.1
TTL 255, TOS 0, NHT 0, MTU 1480
Syntax: show ip tunnels number
The number parameter indicates the tunnel interface number for which you want to display
information.
