Command
History
Version 9.3(0.1) Introduced on the S6000 and Z9000.
Version 9.4(0.0) Introduced on the S4810, S4820T, S6000 and Z9000.
Usage
Information
The ip unnumbered command fails in two conditions:
• If the logical ip address is configured.
• If Tunnel mode is ipv6ip (where ip address over tunnel interface is not possible).
To ping the unnumbered tunnels, the logical address route information must be
present at both the ends.
NOTE: The ipv6 unnumbered command can specify an interface name that
does not exist or does not have a configured IPv6 address. The tunnel
interface is not changed to operationally up until the logical ip address is
identified from the one of the address family.
Usage
Information
The ipv6 unnumbered command will fail if the tunnel interface already has an
explicit IPv6 address assigned. Likewise the ipv6 address command will fail if ipv6
unnumbered is already configured. While unlikely, an interface can be configured
to be ipv6 unnumbered for IPv6 while also having an explicit IPv4 address.
NOTE: The ipv6 unnumbered command can specify an interface name that
does not exist or does not have a configured IPv6 address. The tunnel
interface is not changed to operationally up until the logical ip address is
identified from the one of the address family.
