I'm trying to find out if this is a NX-OS bug or a misconfiguration:
I have a switch with 2 interfaces configured as route interface.
eth1/2 has only a link local address: fe80::1
eth1/3 has only an autogenerated link local address.
With a classic router (linux box, …), it is perfect possible to define a default route with gateway fe80::1%eth1/3
But when I try to do that on nx-os 9.2.3, it refuses to create the route with the error: Next-hop cannot be a local address
IMHO, this error is meaningless as "fe80::1%eth1/3" is not a local address. If I use an other next-hop address (fe80::2%eth1/3) or if I change the eth1/2 address, everything works fine.
My config is like this:
interface Ethernet1/2
no switchport
ipv6 link-local fe80::1
interface Ethernet1/3
no switchport
ipv6 address use-link-local-only
I try to create the route using the following command:
nexus(config)# ipv6 route ::/0 fe80::1 eth1/3
Next-hop cannot be a local address
And the IPv6 interface state is:
nexus(config)# sh ipv6 int
