Service Manual

9.4(0.0) Introduced on the MXL.
Usage Information
The ip unnumbered command will fail in two condition:
• If the logical ip address is configured.
• If the tunnel mode is ipv6ip (where ip address over tunnel interface is not possible).
To ping the unnumbered tunnels the logical address route information should be present in both the ends.
NOTE: The ipv6 unnumbered command can specify an interface name that does not yet exist, or does
not yet have a configured IPv6 address. But the tunnel interface will not go operationally up until it has
determined a logical address to use of at least one address family.
