Display IPv6 discovery information. Entering the command without options shows all the IPv6 neighbor addresses stored on the control
processor (CP).
Syntax
show ipv6 neighbors [vrf vrf-name] [ipv6-address| interface interface]
Parameters
vrf vrf-name (OPTIONAL) Enter the keyword vrf followed by the name of the VRF to display the
neighbors corresponding to that VRF.
NOTE: If you do not specify this option, neighbors corresponding to the default
VRF are displayed.
ipv6-address Enter the IPv6 address of the neighbor in the x:x:x:x::x format.
NOTE: The :: notation species successive hexadecimal elds of zero.
interface interface Enter the keyword interface then the interface type and slot/port or number
