Information
The
ip unnumbered
command fails in two conditions:
• If the logical IP address is configured.
• If the tunnel mode is IPv6IP (where an IP address over a tunnel interface is not
supported).
To ping an IP-unnumbered tunnel, the logical address route information must be
present at both the source and destination ends of the tunnel.
